What is the Process?

The very first thing you will do is to choose a house plan from the Siam Design House Catalog. Examples and free plans are available online at https://siam-design.com. We will discuss the house layout according to the project site and house materials to be used. From there, we will submit a schematic plan. Once you are satisfied with the layout, we will proceed with a 3d model of your desired layout so that you will see the overall design. As soon as the plans and details are confirmed, you will receive a full digital house presentation (animation + PDF- A4 ready-to-print). We will then prepare and apply for a building permit for your house project. To process the building permit, you will have to present the following documents:

  • Land title – Chanot or Nor Sor 3

  • DBD (company information)

  • ID / PASSPORT copy of landowner.

Once issued, you will receive a complete set of construction drawings and the building permit certificate. As soon as all documents are ready, we will now proceed with the construction. This typically starts 2-4 weeks from order day.
