About us
Resort-style homes designed and built by architects and construction managers with more than 20 years of experience.

The "Ayutthaya Builder" team has been building homes and general buildings for more than 20 years. That experience grew into a company, registered as Ayutthaya Builder Co., Ltd.
We pair construction to a high standard with distinctive home design that answers each owner's needs for beauty and everyday function. We select grade-A materials and build structures that are sound and engineered correctly.
A complete service
From proposing a design that suits your land and refining it to your needs, to the building permit and construction under close, systematic supervision. You receive regular progress reports and can inspect every stage until completion. We also advise on — or carry out — interior design and landscaping.
ISO 9001 quality management
Good service, consistent standards, on-time delivery and continuous improvement, for satisfied clients.
Architecture policy
We design homes for true rest: distinctive, beautiful, in tune with nature, and suited to their surroundings and climate — with attention to every detail, so owners take pride in their home.

- Develop and control our construction system to deliver quality, standard-compliant work.
- Supervise every project for the highest quality, on time and to plan.
