Same price per square metre, not the same building
Quotes for site-built prefab buildings are typically 5,500–9,000 THB per square metre — but that figure leaves some things out.
| Container To Build knock-down unit | Typical site-built prefab | |
|---|---|---|
| Floor | Floor frame and flooring included — no concrete slab needed | A concrete slab must be poured first, charged separately |
| Walls | PU-foam insulated walls and ceiling | Often steel sheet and board only, no insulation |
| Electrics | Wired in our factory | Depends on the quote |
| Installation | Craned in and installed in one day | Several days to several weeks |
| Relocation | Lift and move the whole unit | Dismantle and rebuild |
Before comparing quotes, ask these four questions
- Is the concrete slab or foundation included?
- Are the walls insulated?
- Is the electrical work included?
- Can it be moved after the project ends?
Put all four into each quote, then compare the totals. See the floor and the wall core for yourself at our showroom.
Everything you should know before buying
We write this on every page because it matters to your decision.
- Condition: new, built in our own factory.
- This price includes the steel frame, PU-foam insulated walls and ceiling, floor, wiring and TOSTEM doors and windows.
- The floor is built in — no concrete slab is needed, only level ground. Most site-built prefab needs a concrete slab first, charged separately.
- This price does not include delivery or crane unloading, which are quoted by distance to your site before you decide.
- This product is several units joined together. It cannot be moved as one piece: the joints are taken apart, each unit is transported separately, and they are joined again on site.
- A knock-down unit is not a permanent masonry building. With normal care it lasts 20–30 years; Thailand's 2026 construction-cost appraisal table gives knock-down houses a 20-year life and masonry houses 50.
- Whether a building permit is needed depends on local regulations and the local authority decides — check before ordering. If you need to apply, we prepare the documents (paid service).
- It can be moved to a new site by separating it into single units first and rejoining them there — no walls are demolished. Suited to leased land.
- A unit you buy never ends up as scrap: you can move it, resell it or sell it back, so it keeps its value — unlike a building fixed to the land, which has to be demolished when you no longer need it.
- Lead time: 2–3 days from stock, 3–7 days if built to order, installed on site in one day.
- Payment: credit-card instalments are available, subject to your card issuer's terms.
- You can check every point above in person — including the floor and the wall core — at our Bangna and Suwinthawong showrooms.

Product details
WL design house with internal bathroom — two storeys, 6 units, 2 balconies
A two-storey WL-series knock-down building assembled from six 3.00 × 6.00 × 2.60 m units with two balconies, giving 108 m² of usable space in total. The building shown is a delivered project, used as offices and living space on the same plot.
What sets this one apart is that the bathrooms are inside the building rather than in a separate toilet unit, as is usual on knock-down jobs. Nobody has to walk outside at night or in the rain. Each bathroom is tiled and comes with a WC, basin, mirror, shelf and extractor fan.
What you can see in the photos
- Two storeys from six units, with two upper balconies railed along their length
- External steel stair to the upper floor, so no internal floor area is lost
- Bathrooms inside the building, tiled and fully fitted
- Open rooms formed by joining two units, giving width with no central column
- Sliding glass doors, hinged doors and white-framed sliding windows
- Air conditioning already installed (condensers visible on the outside walls)
- Smooth cream interior walls, terrazzo-pattern flooring, long ceiling lights
WL series specification
- Guttered roof
- 15 cm columns with a PVC drain pipe inside
- 40 mm insulation
- TIS-standard steel structure
- TOSTEM doors and windows
- Can be stacked two storeys
- No forklift pockets (unlike the WH series)
1,070,000 THB (9,910 THB/m²) for the whole building as shown (factory price, excluding transport, craning and foundation work). The number of units, the layout and the position of the bathrooms are all made to order. Tell us the site and the budget and we will come back with a design and a price — or come and see our units at the showroom on any working day.
