Which condo floor is best when you compare high and low floors

Key Highlights

• The price gap between high and low floors inside the same building runs roughly 15 to 25 percent, according to superagent.co published on 29 April 2026
• That percentage is similar across Bangkok, but the baht amount is not. A 35 square metre unit in Chidlom carries a floor premium of about 1,869,000 baht, while the same size unit in Bang Na carries about 749,000 baht
• Common area fees are charged per square metre, not per floor. A unit on the 30th floor and a unit of the same size on the 5th floor pay the same
• Any building 23 metres or higher above road level counts as a high building, so it must have automatic fire suppression, a fire lift and fire escape stairs under Ministerial Regulation No. 33 of 1992
• Foreign buyers face two extra constraints that make the floor premium heavier, a lower loan to value ratio and the fact that the reduced transfer fee measure does not apply to them
• Prices and availability are subject to change and are not guaranteed. This content is not legal, tax, or financial advice.

Which condo floor is best for living in versus renting out?

The short answer is that no single floor suits everyone equally. There is a floor that fits your situation better than the others, and the test you use to find it changes completely depending on whether you plan to live in the unit or let it out.

If you are moving in yourself, start with what actually disrupts your day. If it is traffic noise and street level dust, height genuinely helps. If it is waiting for lifts in the morning rush and going up and down several times a day, a low to middle floor gives you a smoother routine.

If you are buying to let, the arithmetic is different. The money you pay to move up is a lump sum due today, while the extra rent comes back month by month. Those two figures have to be compared with real numbers, not with the assumption that a better view must be easier to rent.

This guide works through the five things that decide it in practice, price, noise and dust, wind and sunlight and power bills, evacuation and safety, and how easily the unit resells or rents. It closes with the floor premium converted into baht by district, which is the figure most pages leave out.

Which condo floor suits which resident, based on how you live?

Matching the floor to the resident is the fastest way to cut the list down, because each group runs into a different hard limit and you do not need to compare every floor in the tower.

Resident group	Floor band that fits	Why
Families with young children or older relatives	Low to lower middle floors	Both lift waiting time and the time needed to walk down when lifts are out are visibly shorter
People who work from home	Upper middle floors and above	Traffic noise and noise from the amenity deck fade with height
Anyone sensitive to dust or with respiratory issues	Higher floors	Height does help, but wind direction and the position of neighbouring towers matter just as much as the floor number
Pet owners	Low floors	More practical for several walks a day. Always check the juristic person rules first, because every building sets its own conditions
Landlords letting the unit out	Upper middle floors	Usually the easiest to keep occupied, because the rent still sits inside the range most tenants accept while the view and the quiet are already good

One point applies to every group. Towers differ in height, so a high floor in an eight storey building and a high floor in a forty storey building mean very different things. Think in terms of your position within the building, not the floor number on the door.

Low, middle and upper floors compared on the four deciding points

The four subsections below apply the same frame to all three floor bands so they can be read side by side. The bands follow the definitions superagent.co used in its Bangkok market analysis of 29 April 2026, where low means floors 5 to 10, middle means floors 12 to 20 in towers of 30 storeys or more, and upper means floor 25 and above.

How much does price per square metre differ between low and upper floors

Floor band	Price per square metre
Low floors	The lowest of the three bands and the base used for comparison
Middle floors	Between the two, and superagent.co describes this band as the best value for what you get
Upper floors	Roughly 15 to 25 percent above low floors inside the same building

The rental side makes this easier to picture. superagent.co gives three Bangkok examples. A project in the Chatuchak and Mo Chit area shows a gap of roughly 3,000 to 5,000 baht per month between low and high floors, a project in the Siam and Ratchathewi area roughly 3,000 to 4,000 baht per month, and a project in the Asok area, which is inner city, roughly 7,000 to 10,000 baht per month and above.

The pattern in those three examples is consistent. The closer you get to the city centre, the wider the floor gap becomes, because an open view is scarcer where towers stand close together and inner city tenants have more to spend.

One caution when reading these figures. They are rents for the specific projects named in that source, not market averages. Use them as a starting frame, then ask the sales team or look at listings currently available in the building you are considering for the real numbers.

Do noise, dust and insects really ease off on upper floors

Floor band	Noise, dust and insects
Low floors	Take the most street noise and ground level dust, and are the band where insects appear most often
Middle floors	Already clear of ground level noise and dust, though in some buildings you still hear the amenity deck and the car park
Upper floors	Noticeably quieter from street traffic, with superagent.co noting the drop becomes clear from floor 20 upwards, and they see the least dust and the fewest insects

The common mistake is assuming height solves every kind of noise. Height only helps with noise that originates at ground level. Noise generated inside the building, such as lifts, footsteps in the corridor, the neighbouring unit and machinery, does not fade with height at all.

A test you can run yourself during a viewing. Stand in the unit with the door and windows fully shut and listen carefully for a full minute, then open a window and listen for another minute. If the two are similar, what you are hearing comes from inside the building, and moving up will not help.

One figure we could not source reliably is average PM2.5 by floor height in Bangkok, so no number is given here. The workable substitute is to take the reading from the monitoring station closest to the building as your base, and treat height as a directional advantage rather than a measured one.

Wind, sunlight and power bills, is an upper floor hotter or cooler

Floor band	Wind, sun and heat
Low floors	Get the least wind because neighbouring buildings block it, and often get shade from those same buildings
Middle floors	Get a reasonable amount of wind without it becoming strong enough to make the balcony unusable
Upper floors	Get the strongest wind and the most direct sun, especially the top floor, which takes heat through the walls and from the roof slab at the same time

Sunlight has to be read together with orientation, not with the floor alone. According to baanlaesuan.com, the sun tracks to the south of overhead from September to April in Thailand and slightly to the north from May to August, which makes a west facing unit the hottest all year because it takes the afternoon sun when accumulated heat peaks.

Wind has its own calendar. The Thai Meteorological Department states that the southwest monsoon runs from mid May to mid October and the northeast monsoon from around mid October to mid February. A unit oriented to catch one of them gets good airflow for about half the year rather than all year.

On electricity we found no source reporting average bills by floor for Thai condominiums, so no figure is given. The more direct approach is to calculate it from the air conditioner, which is the main draw. Divide the BTU rating by the SEER rating, divide by 1,000, then multiply by hours of use, by the number of days, and by the rate per unit.

For the rate in that formula, origin.co.th published on 10 June 2026 states that the average electricity tariff for the May to August 2026 cycle sits at 3.95 baht per unit with an Ft component of 0.1623 baht per unit, and that the residential category averages roughly 3.70 to 4.15 baht per unit.

One worry you can take off the list. Common area fees are charged as baht per square metre per month, not by floor, so units of the same size on the 5th and the 30th floor pay the same. Market rates we found sit in the range of roughly 23 to 75 baht per square metre per month, while sansiri.com, updated 24 November 2025, gives a range of 40 to 85 baht. The two ranges differ because each source draws on a different set of projects, so ask the building for its actual rate.

Evacuation and safety, what does Thai law already require

Floor band	Evacuation and safety
Low floors	Reach ground level fastest when lifts are unavailable, and are the easiest for responders to reach
Middle floors	Take a moderate time on the stairs and remain within a distance most people can walk down in one go
Upper floors	Take the longest on the stairs and depend most on building systems, including fire escape stairs, automatic suppression and the fire lift

What makes this manageable is that the law already sets fairly detailed standards for tall buildings. Under Ministerial Regulation No. 33 of 1992, a building measuring 23 metres or more from road level counts as a high building, and a building with a combined floor area of 10,000 square metres or more counts as an extra large building.

The safety requirements residents should know exist include an automatic fire suppression system covering every floor, at least one fire lift reaching every floor, at least two fire escape stairs, a refuge room of not less than 6 square metres beside the escape route on each floor, and a dedicated firefighting water reserve that must hold minimum pressure at the top floor.

One requirement affects fire engine access directly. The same regulation requires a high building to have a road with a traffic surface at least 6 metres wide so fire vehicles can reach it. You can check this with your own eyes during a site visit by walking the perimeter and seeing whether large vehicles could genuinely reach every side.

Three questions worth putting to the juristic person before you decide. When was the last evacuation drill, when was the automatic suppression system last inspected, and are the fire stairs clear of obstruction and storage. Those three answers tell you more about how the building is run than the floor number does.

A note on project size. According to the Office of Natural Resources and Environmental Policy and Planning, a condominium with 80 units or more, or with a usable area of 4,000 square metres or more, must produce an environmental impact assessment. That threshold is not tied to height, so a low building with many units can fall inside it while a tall building with few units may not.

How much is the floor premium in baht in each district?

Most pages stop at the statement that upper floors cost roughly 15 to 25 percent more. The problem is that a percentage is not what you have to fund. What you fund is an amount, and the amount behind the same percentage varies several times over once you change district.

The figures below take price per square metre by district from bambooroutes.com, updated 2 April 2026, multiply it by a 35 square metre unit, then apply a floor premium at the midpoint rate of 20 percent. Every figure is a frame for opening a negotiation, not a valuation of any particular unit.

Chidlom and Langsuan

Chidlom and Langsuan sit at the premium end of central Bangkok, which is why the gap between a low floor and a high floor is wider here than anywhere else in this comparison. Start with condos for sale in Langsuan if you want a feel for what that upward move actually costs.

• Price per square metre 267,000 baht
• Price frame for a 35 square metre unit 9,345,000 baht
• Extra amount to move up to an upper floor 1,869,000 baht

Silom and Sala Daeng

Silom and Sala Daeng put you in the middle of the banking district, so the floor you pick here is as much about street noise as it is about the view. Have a look at condos for sale near Sala Daeng to see how the premium plays out at this end of town.

• Price per square metre 252,000 baht
• Price frame for a 35 square metre unit 8,820,000 baht
• Extra amount to move up to an upper floor 1,764,000 baht

Thong Lo

Thong Lo draws a crowd that stays late for the food and the bars, and that same energy is the reason a higher floor is worth thinking about here. Browse condos for sale in Thong Lo before you settle on a floor band.

• Price per square metre 246,000 baht
• Price frame for a 35 square metre unit 8,610,000 baht
• Extra amount to move up to an upper floor 1,722,000 baht

Asok

Asok is where the BTS and the MRT meet, so the towers here stand tall, dense and close together. Scanning condos for sale near Asok shows how quickly the outlook changes once you move up a few floors.

• Price per square metre 214,000 baht
• Price frame for a 35 square metre unit 7,490,000 baht
• Extra amount to move up to an upper floor 1,498,000 baht

Rama 9

Rama 9 has grown into a second office cluster, and the price per square metre there sits well below the older central stations. Comparing condos for sale near Rama 9 is a good way to see what a mid range budget buys once you move up.

• Price per square metre 163,000 baht
• Price frame for a 35 square metre unit 5,705,000 baht
• Extra amount to move up to an upper floor 1,141,000 baht

On Nut

On Nut is the point on the Sukhumvit line where budgets start to relax without giving up the train at your door. Browsing condos for sale near On Nut helps you see how far the floor premium stretches at this price level.

• Price per square metre 132,000 baht
• Price frame for a 35 square metre unit 4,620,000 baht
• Extra amount to move up to an upper floor 924,000 baht

Bang Na

Bang Na sits at the outer end of the line, where lower land values mean the cost of moving up a floor is the smallest in this list. Start with condos for sale near Bang Na if the view matters more to you than the address.

• Price per square metre 107,000 baht
• Price frame for a 35 square metre unit 3,745,000 baht
• Extra amount to move up to an upper floor 749,000 baht

What these seven districts show is that the floor premium in Chidlom and the floor premium in Bang Na differ by 1,120,000 baht, for the same percentage and the same unit size. In inner city districts, moving up a floor band is a decision measured in millions. Further out it is measured in hundreds of thousands.

The practical consequence for anyone on a tight budget. If your cash will not stretch to both the district you want and the floor you want, moving out one station usually frees more budget than dropping to a low floor in the same district, because the whole price per square metre base comes down rather than just the floor premium.

One cost people forget to add. The floor premium is part of the purchase price, so if you resell within five years of acquiring ownership, specific business tax at 3.3 percent applies to the full sale price including that premium. On the 1,869,000 baht premium in Chidlom alone that is roughly another 61,677 baht. Hold for the full five years and meet the house registration conditions and it becomes stamp duty at 0.5 percent instead.

There is also a case where the floor premium pushes you across a fee threshold. The Cabinet resolution of 30 June 2026 extended the reduction of the transfer registration fee from 2 percent to 0.01 percent and the mortgage registration fee from 1 percent to 0.01 percent through 30 June 2027, capped at a sale price and appraised value of no more than 7 million baht per contract, for individual buyers of Thai nationality who register the transfer and the mortgage at the same time.

A worked example makes the effect clear. A 40 square metre unit in Rama 9 at 163,000 baht per square metre comes to 6,520,000 baht, still under the 7 million baht cap. Add the floor premium at the 20 percent midpoint and the price moves to 7,824,000 baht, which is over the cap. The transfer registration fee then changes from 652 baht at 0.01 percent to 156,480 baht at the normal 2 percent, a difference of 155,828 baht, and the mortgage registration fee reverts to 1 percent as well.

The lesson is simple. If the unit you are looking at sits near the 7 million baht cap, calculate the fees both ways before you agree to pay for a higher floor, because the real cost of moving up in that situation is the premium plus the fees you lose access to.

What two extra points apply only to foreign buyers?

The first point is financing. Data from expatica.com updated 2 February 2026 shows foreign borrowers typically receive around 50 to 70 percent of property value, with interest around 5 to 8 percent and terms of 15 to 30 years. Our own guide on loans for foreigners in Thailand records age criteria of 21 to 55 and income requirements of roughly 80,000 to 140,000 baht per month, with UOB lending up to 70 percent over a maximum 35 years.

Applied to the Asok example, the 1,498,000 baht floor premium has to be funded with more cash than a Thai buyer would need. At 70 percent lending you fund about 449,400 baht of that premium yourself, and at 50 percent lending about 749,000 baht. Because the reduced transfer fee measure applies to individual buyers of Thai nationality, a foreign buyer also pays the normal fee rates on the whole price including the premium.

The second point is what kind of ownership is left in the building. Foreign buyers may hold freehold title to condominium units totalling no more than 49 percent of the aggregate unit floor area in a building. Because the quota is measured by area rather than by unit count, larger units consume more of it, and older towers beside major stations have often used the quota up already.

This connects to your floor choice more than it first appears. Upper floor units in a well established tower are often the ones sold earliest and held longest, so the freehold units still available may sit on lower floors, or the upper floor unit you want may only be offered on a leasehold basis. That changes the comparison entirely, because a leasehold unit and a freehold unit are not the same asset. Ask the seller in writing which basis applies before you place a deposit.

One paperwork note that follows the money. Funds transferred in from abroad above 50,000 US dollars require a foreign exchange transaction form from the receiving bank, and the sender name and stated purpose must match the name going on the title. Since the floor premium raises the total you remit, plan the transfer around the higher figure rather than the base price.

Which floors do people overlook, and which floors should you avoid?

Inside any single tower some floors are priced down for reasons you can work around, and some look fine on paper but carry problems you cannot fix. Knowing both groups helps more than comparing every floor one by one.

The floor above the amenity deck and the floor beside the machine floor

Units directly above the pool, gym or shared lounge are usually priced below their neighbours because of activity noise and foot traffic. The upside is that if you leave early and come home late, the hours when the amenity deck is busiest are the hours you are out, so the discount is one where you do not pay the full inconvenience.

Units beside the machine floor are also priced down, but this group needs more caution. Machinery noise and vibration run continuously through the day and the night rather than in bursts like the amenity deck. The most direct check is to ask to stand in the unit at night or during the period when the building runs its plant hardest.

Floor 13 is a special case that many buildings label 12A. According to livingpop.com, published 31 July 2019 and updated 14 September 2025, some projects offer a discount on this floor. If the superstition does not concern you, this is a place where a price advantage can still be found in some buildings.

The top floor, the lowest residential floor and units beside the refuse room

The top floor takes heat through the walls and from the roof slab at the same time during the day, and carries a higher risk of water ingress from the roof in heavy rain. Both jorakay.co.th and livingpop.com agree on this point.

The lowest residential floor is the one most buyers never think about. According to livingpop.com, the horizontal drainage runs at this level are more prone to blockage than elsewhere, and when they block the floor directly above is affected too. You can check it by asking the juristic person whether there has been a drainage blockage at that level in the past three years.

Units beside the refuse room, beside a storage room, or facing the lift lobby are three positions where the noise and the smell come from inside the building, which height does not fix. Open the floor plate and look at where the unit sits relative to those three points before you decide, rather than looking only at the floor number.

One encumbrance that has nothing to do with the floor but blocks the transfer. A unit with unpaid common area fees cannot be transferred until a debt free certificate is issued, and late payment interest under condominium law is capped at 12 percent per year, rising to no more than 20 percent per year once the arrears reach six months. Ask for that certificate before you place a deposit on any resale unit, whatever floor it is on.

Which floors rent and resell faster, and how many years to recover?

This question cannot be answered by instinct. You have to compare the lump sum paid today against the extra rent received each month. The example below uses Asok because it is the district where both sides of the figure are available.

The assumptions are a 35 square metre unit in Asok, a purchase price difference of 1,498,000 baht to move up to an upper floor as calculated above, and a rent difference between low and high floors in that district of 7,000 to 10,000 baht per month based on the superagent.co example.

• Extra rent received per year 84,000 to 120,000 baht
• Time to recover the premium 12.5 to 17.8 years, before deducting vacant periods and other costs
• Gross return calculated on the floor premium alone 5.6 to 8.0 percent per year

What makes this interesting is that the gross return on the premium alone sits above the gross return on the whole unit in the same district. bambooroutes.com, updated 8 May 2026, puts gross yields in Asok at 3.3 percent for studios, 3.8 percent for one bedroom units and 4.4 percent for two bedroom units.

Read it carefully. The two figures come from sources that collect data differently, and the calculation assumes a 35 square metre unit with no allowance for vacancy. Treat it as a frame for the questions you put to the sales team, not as a promise that your actual return will land at these levels. For the full method covering gross, net and cash on cash returns, see the PropertyScout rental yield guide.

What this tells a landlord is that paying up for height in an inner city district has more support behind it than most people assume. A recovery period beyond a decade also means the argument works for someone holding long term, not for someone planning to resell in three to five years.

On resale, upper middle floors tend to reach the widest pool of buyers, because they remain inside the price band the largest group can consider. Top floor units face a narrower pool, since fewer people are ready to fund a premium in the millions for a view than are looking for a mid market unit.

If you can pick only one, floor or orientation?

It depends on what can be fixed later and what cannot. Orientation cannot be changed at all, and it affects every day of the year through heat and power bills. The floor cannot be changed either, but its effect on several of the points above stops improving past a certain level.

The reason we lean towards weighting orientation more heavily is that the noise and dust benefit of height has a ceiling. Past floor 20, the level superagent.co identifies, going up another ten floors costs hundreds of thousands to millions more without noise falling in proportion, whereas a west facing unit takes the afternoon sun every day on any floor.

Two situations reverse that order. The first is a unit boxed in by neighbouring towers so that it gets neither light nor airflow, where rising above the height of the obstruction does more than any orientation choice. The second is a site beside a main road or an expressway, where ground level noise and dust are severe enough to decide the quality of living on their own.

A decision rule you can use during a viewing. Answer these three in order. Is anything blocking light and airflow, does the unit face west, and is the noise you hear coming from the street or from inside the building. Those answers will tell you whether your case should pay for the floor or for the orientation.

Frequently asked questions about which condo floor is best

Which floor should you choose when buying a condo to live in long term

If you are living in it long term and budget is not the binding constraint, the upper middle band suits most people best, because it is clear of ground level noise and dust, does not carry the full upper floor premium, and still leaves the walk down manageable when lifts fail. From there, remove the floor beside the machine floor, the floor above the amenity deck, the top floor and the lowest residential floor, then choose an orientation other than west.

How much more does a high floor condo cost than a low floor one

According to superagent.co published on 29 April 2026 the gap runs roughly 15 to 25 percent inside the same building, but the amount you actually pay depends on the district. For a 35 square metre unit the premium at the 20 percent midpoint is about 1,869,000 baht in Chidlom and about 749,000 baht in Bang Na. Convert the percentage into baht before you decide.

Do high floor units pay higher common area fees

No. Common area fees are charged as baht per square metre per month and do not depend on the floor, so units of the same size on the 5th and the 30th floor pay the same. What changes with height is the purchase price and the rent, not the common area fee.

Is a high floor unit hard to live in during a power cut, and can you evacuate in time

Walking down from an upper floor certainly takes longer. That said, any building 23 metres or more above road level counts as a high building under Ministerial Regulation No. 33 of 1992, so it must have automatic fire suppression on every floor, a fire lift and at least two fire escape stairs. What decides real safety is how well those systems are maintained, so ask the juristic person when the last drill and the last inspection took place.

Which floor is easiest to rent out

The upper middle band usually stays occupied most consistently, because the rent remains inside the range the largest group of tenants accepts, while top floor units face a narrower pool. If you are weighing whether to pay for height, multiply the rent difference by 12 and divide by the purchase price difference. The result is the gross return on that lump sum, which you can then compare against the yield on the whole unit in the same district.

As a foreign buyer, does the floor affect whether I can own the unit freehold

Not directly, but it often works out that way in practice. The 49 percent foreign ownership quota is measured by aggregate unit floor area rather than by unit count, and in older towers beside major stations the quota is frequently used up. The units still available on a freehold basis may therefore sit on lower floors, or the upper floor unit you want may only be offered as a leasehold. Ask for written confirmation of the ownership basis before paying any deposit.

Summary

Start by answering whether you are buying to live in or to let, because the test differs from the first step. If you are living in it, begin with whatever disrupts your day most. If you are letting it, begin by comparing the purchase price difference against the rent difference as numbers.

Next, convert the percentage into baht, because a 20 percent premium is a decision in the millions in inner city districts and a decision in the hundreds of thousands further out. Then strike out the floors with problems that cannot be fixed, the top floor, the floor beside the machine floor, the lowest residential floor, and any unit facing the lift lobby or next to the refuse room.

Finish with three checks on site. Is anything blocking light and airflow, does the unit face west, and is the noise coming from the street or from inside the building. Those three cut the list down faster than comparing every floor in the tower.

When you are ready to view, condo listings for rent and for sale in Bangkok on PropertyScout state the floor and the orientation on every listing, so you can compare floor against orientation inside the same building before booking a viewing.
