Best House Builder in Khon Kaen



- I want to build a house. How much will it cost?

We won´t be able to give you a satisfying answer. We have no idea how big your house shall be, how many floors, do you need a swimming pool, how is the land plot (ready to build?) and which building standard you need.

Also we have no idea which building style you like, which kind of roof you want and which extras your house will include. 

A standard answer we can give you here:

Your house will cost between 1,000,000 THB up to 100,000,000 Thb.

- Why are your houses expensive? My local builder does the same house for half of the money!

"If you think a professional is expensive, try to hire an amateur."

We are not more expensive than any other professional builder. Yes, there are local builders in some villages you have heard of, or a family member know them. And sure they will tell you it´s all A-Grade.


The question is: What is your vision of an A-Grade house, what is their vision of A-Grade?

I, Punjaree Hofmann, did long time ago, before I even was in the building business, the same fault, and hired people my family knew. What a desaster, and at the end I paid on top. The renovation / building project was more expensive than by a professional builder, and it was never to 100% as planned.

We also had clients who built before with local, non official companies. We had to pull down many started projects and started from zero again. 

- I came to your office, but no one was there!

If you like to visit our office, please make an appointment via our contact form or simply leave your number and we will call you. If we make an appointment and get your visions in front, we will be also prepared for our meeting and can give you more details and answers to all your questions.

- Why do I have to pay for the building plans, you said they are for free.

Our goal is to make for every client a unique house, due to every client is unique. The money we earn, we want to earn with the building itself. There is no money to earn with building plans. So we give you our building plans for free, if you decide to build with us. If you find someone else who shall build your house, the deposit for your building plan stays with us due to we have spent a lot of time doing it. A Ready - To- Build - Building plan is not done within 2 hours. And for sure, you can use the building plans with another builder.


- The contract says 2 weeks, now it took already 4 weeks. 

A usual building plan is done within 2 weeks time. If you have multiple changes to do or want special renders of your plan, it will extend the time to finish. The floor plan and renders are the pre-work of your building plan. If this is to 100% to your satisfaction, the real work starts and takes up to two weeks.

- My wife/husband has land, let´s build. What should go wrong?

In our history, we have seen a lot of relationships fail to work and,if the foreign part was the one who paid for the whole construction, was left with nothing. Do yourself a favor: If you are a foreigner and you would like to pay for the whole construction, at least get a 30 years lease with/from your Thai partner. We can´t say that often enough.

- I´m planning to build a house, what do you need?

If you plan to build a house in Thailand, and it should not be a standard house off the shelf, then we need to know as much as possible from your visions.

- Pictures of houses you like (taken from the internet or your own photographs) Or chose one of our design concepts.

- a floor plan (very simple, just a sketch is enough)

- tell us what you like, show us designs you like, ...everything what can help us to imagine.

The construction process


Every construction process is unique and depends on the scope and complexity of the project. But each time a sustainable house is built, the process follows typical steps, and the principles are similar for smaller scale projects like renovations.What do you have to do if you want to build your house in Khon Kaen or Isaan?!


Choosing your builder in Khon Kaen.


Before you get to the stage of choosing a builder in Khon Kaen, your research and design process will have yielded finished design documents to put out for tender by builders. If you have no design ideas yet, contact your professional home builder in Khon Kaen now.


Sanmanoch&Hofmann will give you the fairest quotation and best quality in building material and modern design of your choice.


In either case, note in your tender documents that you are ‘not obliged to accept the lowest or any tender’.

Our architect and designer in Khon Kaen generally helps choose builders to tender for a project, based on recommendations and past experience.Sanmanoch&HOFMANN has experience for more than 20 years. 


Your choice of builder is almost as critical as your choice of a designer. With Sanmanoch&Hofmann, you can find both. We have a professional designer and architect in Khon Kaen, also an engineer  who gurantees a professional building plan which is also accepted by the land office.

The principal role of Sanmanoch&HOFMANN, your house builder in Khon Kaen, is to coordinate the building works as project manager. This role includes supervising and coordinating each trade; sourcing, quantifying and coordinating delivery of materials; and, most importantly, quality-assuring the entire process! 


Some builders and trades people are understandably risk-averse and tend to manage risk by using tried and proven materials and practices. Sustainable outcomes often require the use of innovative materials and practices. To avoid problems later, ensure each builder is made aware of your commitment to a sustainable home when they are invited to tender. Sanmanoch&Hofmann, your Khon Kaen Construction Company, is also in this case the right choice.
