What a steel frame package includes, and what it does not
APEX LGS supplies the steel structure of your building, engineered, made in our Lamai factory and erected on your site. We don't build the whole house. Knowing where our work ends and your builder's begins makes planning, pricing and scheduling much easier.

What APEX supplies
- An estimate within 6 hours. Send drawings, a sketch or a brief, and we send back a budget estimate for the steel structure.
- Design and engineering. We turn your plans, or your architect's, into an engineered steel model. Every stud, truss and connection is sized before fabrication.
- Permit drawings. Drawings and calculations signed by a licensed Thai structural engineer, ready for your building permit.
- A factory-made frame. Every stud is roll-formed, cut to length, pre-punched and numbered in Lamai, then bundled in build order.
- Erection on site. Our crew stands the wall frames and roof trusses on your slab. For a villa this takes days, not months.
What your builder does
Once the frame is up, your own builder or contractor takes over. Typically that covers:
- Foundations and slab, before the frame arrives.
- Roof covering, external cladding and internal linings.
- Windows and doors.
- Plumbing and electrical work.
- Floors, kitchens, bathrooms and other finishes.
- Pool, decks and landscaping.
Every estimate we send lists exactly what is in and out of our scope for your project, so there are no gaps between us and your builder.
How the handover to your builder works
Because the frame follows the engineered model to about 1 mm, your builder works on straight, square walls. Pre-punched holes in the studs are already placed for services, which saves cutting on site. We share the frame drawings with your builder before we arrive, so the slab, anchors and openings match.
Builders and contractors
If you are a builder, you can order engineered frame kits for your own projects and crews, with APEX technical support. See our partner programmes.
Send your plans, get a frame estimate in 6 hours.
Drawings, a sketch or a short brief is enough. Request an estimate or message us on WhatsApp.
Frequently asked questions
Do you build complete villas?
No. APEX engineers, fabricates and erects the steel frame and roof trusses. Your builder finishes the house.
Can you work with my builder?
Yes. We share the frame drawings before delivery so the slab, anchors and openings match, and our crew coordinates the erection date with your builder.
