We often get asked how much does it cost to build a house in Thailand, or what are the construction costs in Thailand ? So we will try to offer some insight into what to expect and how to do it correctly.

A professional construction person if genuine, would not give you simply a figure without informing you, that construction costs vary according to the individual project, who is building it, the location and what they provide within their quotation. It is impossible to know accurate construction costs until you have finished architectural drawings, have knowledge of the specifications, size, site conditions, location and what materials are being used. Each house is different, as the architects drawings are different, the materials are different, location and site conditions could be different. Costs are calculated once all architects drawings are completed. A cost quotation can take 2-4 weeks depending on the size of house.

To know costs, the builder has to know from the architects drawings facts such as: what type of materials, product and manufacturer of each material and every aspect of the construction. This includes, windows, roof tiles, doors, electrical systems, sockets, light switches, insulation, wall material, pumps, bathroom finishes, tiles, floor coverings, light fittings, wood, steel, concrete, cement and all the other materials used within the construction. What size, what quantity, what product etc ? They need to know the details and information, then calculate quantities and amounts required to complete the construction. It is the only accurate way to know the construction cost. So to answer how much a house costs to build in Thailand, is a very difficult question to answer, as you can see, it varies according to each project.

What Bangkok Builder does, if our architect is designing the home, is to provide an approximate projected, construction cost, when our architect provides the architectural job description and fee proposal for architecture. It cannot be 100% accurate, as it will change during the design development stage and also we have no knowledge of the materials or specifications yet. But we try to give you an approximate projected guide. It is no guarantee of cost at all and is helpful information based on the architects experience in construction costs. But it gives you some idea for a starting point.

To do construction correctly and follow the correct process, you must work with the architect and have your architectural drawings completed first, before knowing accurate costs to build the house. You can discuss budgets with them and they can try their best to design a home within your budgets. But do remember that any changes or requests you make, during the architectural stage, alter that projected cost. So it is always a good idea if you are on a restrictive budget, to let the architect know in advance.

Approximate Information of House Construction Costs in Thailand: Remember construction costs can increase over time and because of market forces. But as of this date in 2018, we have seen the construction cost for houses in Bangkok to be any where from 25,000 baht per sq.m to 40,000 baht per sq.m, depending on everything we have mentioned in this article. It can be more if the house is high spec and a high end luxury house. But for a good, standard home in Bangkok and Thailand’s mainland provinces, maybe 25,000 to 35,000 baht per sq.m. Can it be less, yes of course. We have seen costs be as low as 20,000 Baht per sq.m for low end, small homes with lower specifications and material standards. Then again we have seen them be a lot higher if you are building on the islands of Koh Samui, or Phuket. As all materials have to be transported to the location. It is not usual to see construction costs of a luxury home on Koh Samui being 50,000 Baht per sq.m or more, for a full fit out. But as we say, it is important to understand that no one can know without a professional cost being done once all architectural drawings are completed.

This is not a cost quotation from us, as we do not have the required information yet, but it is merely a guide to be helpful to give you an approximate idea. But the only true way to know, is have your architectural drawings completed, all specifications and materials known. Then a professional cost quotation done by the construction contractor. It is too misleading to try and guess it without all of that accurate information.
