For villa owners
Build your villa on Koh Samui, faster and straighter
You have the land, or you're about to buy it. You want a villa that's built well, on time, without living on site to supervise. APEX designs, engineers and builds your villa's steel structure from our own factory in Lamai, and can take it through to handover.
What you get
- Design and engineering. We turn your plans, or your architect's, into a fully engineered steel model.
- Permits. Drawings signed by a Thai licensed engineer and submitted for your building permit.
- Factory-made frame. Every stud roll-formed, cut and numbered in Lamai.
- Frame and roof on site. Walls and trusses stand in days, not months.
Built for owners who live abroad
Many of our clients aren't on the island while we build. Because every piece is engineered and numbered in advance, what goes up matches the drawings you approved. You get regular photo and video updates, and one person to call.
