The one-line version

As broad 2025-2026 orientation, mid-rise condominium construction in Bangkok runs roughly THB 28,000-45,000/sqm for standard quality, offices THB 22,000-55,000/sqm depending on grade, retail THB 25,000-45,000/sqm, and industrial/warehouse space as little as THB 8,000-15,000/sqm. Upcountry provinces typically run 10-25% below Bangkok; resort provinces like Phuket and Koh Samui often match or exceed it. These are construction-only ranges — land, fees, and developer costs sit on top — and every real project needs its own contractor quotes.

Why THB/sqm benchmarks are a starting point, not a quote

Every construction cost figure you'll see quoted — including the ranges in this guide — is a broad orientation number for a "typical" building of that type and quality. Real project costs move on a handful of variables that a per-sqm average can't capture:

Site & soil conditions. Soft ground (common around Bangkok and near water) often means piled foundations, which can add a large, project-specific sum that a headline THB/sqm figure doesn't include.
Specification & finish level. The gap between "standard" and "premium" finishes for the same building type is frequently 40-80% of the base construction cost.
Procurement route. A turnkey (design-and-build) contract carries a different risk premium than a traditional design-bid-build tender with a separate quantity surveyor.
Market timing. Steel, cement and skilled-labor pricing move over the course of a year; a quote taken at tender is only valid for a limited window before contractors reprice.

Construction cost by building type (Bangkok, 2025-2026 orientation)

Structure, core M&E and standard finishes, excluding land, design fees, FF&E and developer costs:

THB per square metre of gross floor area

Low-rise apartment / walk-up (under 8 floors) — roughly THB 15,000-25,000/sqm.
Mid-rise condominium, economy/budget — roughly THB 20,000-28,000/sqm.
Mid-rise condominium, standard/mid-range — roughly THB 28,000-45,000/sqm.
High-rise condominium, luxury/premium — roughly THB 45,000-90,000+/sqm, driven up by podium, facade systems, amenity floors and imported finishes.
Office, Grade B — roughly THB 22,000-35,000/sqm.
Office, Grade A / CBD tower — roughly THB 35,000-55,000/sqm.
Retail / shopping center — roughly THB 25,000-45,000/sqm, depending on anchor-tenant fit-out obligations and M&E complexity.
Industrial / logistics warehouse (standard pre-engineered steel) — roughly THB 8,000-15,000/sqm.
Cold storage / high-spec industrial — roughly THB 15,000-25,000+/sqm.

Bangkok vs upcountry vs resort provinces

Bangkok & the metro region sets the baseline used above — the deepest contractor market, most competitive tendering, and shortest supply chains for both materials and equipment.
Secondary cities & upcountry provinces (Isaan, the north, most of the northeast) typically run 10-25% below Bangkok for equivalent specification, mainly on cheaper local labor and shorter local-material haulage, though thinner contractor competition can offset some of the saving on complex or high-rise work.
Resort provinces (Phuket, Koh Samui, Krabi and similar) are the exception — costs there often match or exceed Bangkok, since imported finishes, specialist trades and heavy equipment frequently have to be shipped or trucked in, and much of the private-villa, branded-residence and hotel-grade stock is built to a higher specification than typical Bangkok condominium work.

Material cost drivers

Structural steel & rebar — the most volatile major input; Thailand imports a meaningful share of its steel, so prices track global steel and iron-ore markets and periodic anti-dumping duties on imported steel products.
Cement — largely domestically produced and comparatively stable relative to steel.
Imported finishes & building systems — curtain-wall glass, elevators, chillers and specialist MEP equipment are the most exposed to THB/USD exchange-rate movement, which is why high-rise and luxury projects see materially more cost volatility than economy low-rise work built almost entirely from domestic materials.
Energy-efficiency & green-building specification — increasingly common on institutional-grade office and hotel projects, and it pushes costs up versus a code-minimum building.

Labor cost trends

The Thai construction workforce relies heavily on migrant labor from Myanmar, Cambodia and Laos for general and semi-skilled trades, and minimum-wage increases feed directly into base labor costs across every project type. The tighter structural constraint is skilled finishing trades and MEP specialists — electrical, mechanical, facade and elevator installation — where shortages can extend timelines and push up day rates far more on complex, high-rise or hospital/hotel-grade work than on a standard low-rise build. Projects that depend on a narrow pool of specialist subcontractors should budget contingency for both cost and schedule risk on these trades specifically.

How Thailand compares across Southeast Asia

Thailand generally sits in the middle of the ASEAN range: construction costs run meaningfully below Singapore, are broadly comparable to or a little below Malaysia for equivalent building types and specification, and sit above Vietnam, Cambodia and Laos, where lower labor costs pull per-sqm benchmarks down further. Thailand's advantage is a mature, well-established contractor base, deep materials supply chain and relatively predictable regulatory process, which reduces execution risk relative to some lower-cost neighbors even where the headline THB/sqm figure is a little higher — a relevant factor for developers and investors weighing regional site selection, not just headline cost.

Frequently asked

How much does it cost to build a condominium in Thailand per square metre?As broad 2025-2026 orientation, a standard mid-rise condominium in Bangkok (structure, MEP and standard finishes, excluding land) runs roughly THB 28,000-45,000 per square metre of gross floor area. Economy/budget schemes can come in around THB 20,000-28,000/sqm, while a luxury high-rise tower with a full podium, imported facade systems and high-spec finishes can run THB 45,000-90,000+/sqm. These are construction-cost ranges only; land, design and professional fees, sales and marketing, and developer margin sit on top and are not included in a THB/sqm construction benchmark.

Are construction costs different in Bangkok versus upcountry Thailand?Generally yes, though the gap has narrowed. Secondary cities and upcountry provinces (Isaan, the north, most of the northeast) typically run 10-25% below Bangkok for equivalent specification, driven mainly by cheaper local labor and shorter haulage distances for aggregates and basic materials. Resort provinces such as Phuket and Koh Samui are the exception — costs there can match or exceed Bangkok because imported finishes, specialist trades and equipment often have to be shipped or trucked in, and much of the private-villa and hotel-grade stock is built to a higher specification than typical Bangkok condominium work.

What drives construction material costs in Thailand right now?Structural steel and rebar are the most volatile line items, since Thailand imports a meaningful share of steel and its price tracks global steel and iron-ore markets plus periodic anti-dumping duties on imported steel products. Cement is largely domestically produced and comparatively stable. Imported finishes and building systems — curtain-wall glass, elevators, chillers and specialist MEP equipment — are the most exposed to THB/USD exchange-rate movements, which is why luxury and high-rise projects see more cost volatility than economy low-rise work built almost entirely from domestic materials.

Is skilled labor a bigger cost driver than materials in Thailand?Materials and labor move somewhat independently, but labor supply is the bigger structural risk. The Thai construction workforce leans heavily on migrant labor from Myanmar, Cambodia and Laos for general and semi-skilled trades, and minimum-wage increases feed directly into base labor costs project-wide. The tighter constraint is skilled finishing trades and MEP specialists (electrical, mechanical, facade and elevator installation), where shortages can extend timelines and push up day rates on complex, high-rise or hospital/hotel-grade projects far more than on a standard low-rise build.

How does Thailand's construction cost compare to the rest of Southeast Asia?Thailand generally sits in the middle of the ASEAN range: construction costs run meaningfully below Singapore, are broadly comparable to or a little below Malaysia for equivalent building types and specification, and sit above Vietnam, Cambodia and Laos, where lower labor costs pull per-sqm benchmarks down further. Thailand's advantage is a mature, well-established contractor base and reliable materials supply chain, which reduces execution risk relative to some lower-cost neighbors even where the headline THB/sqm figure is a little higher.

Where do these construction cost figures come from, and how accurate are they for my project?These are broad orientation ranges drawn from industry-standard benchmarking practice, not a quote for any specific project — actual cost depends heavily on site conditions (especially soil and foundation type), exact specification, contractor, procurement route and market timing at the point you tender. Thailand's Department of Public Works and Town & Country Planning (DPT) publishes official government standard construction cost schedules used for permit valuations and public works, and the Bureau of Trade and Economic Indices tracks a Construction Materials Price Index that shows how material costs move over time — both are useful reference points, but for a real project always get written quotes from two or three contractors and, for anything non-trivial, a quantity surveyor's estimate.
