Heat insulation

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.
• ●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).
• ●The whole unit can be lifted and moved without dismantling — a good fit for leased land — and you can add units later.
• ●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.
