About 999 Developments | Pool Villa Builder in Chiang Mai

Our story

From renovating homes to building pool villas

We started with second-hand condos and houses. The homes we saw did not meet our own standards, so we began to build our own, as if we were going to live in them.

What we believe

The most trusted, not the biggest

Our vision

To be known as the benchmark for quality in Chiang Mai real estate. Not the biggest, but the most trusted by those who value well-built homes, thoughtful design and personal service. When people think of quality homes in Chiang Mai, they think of us.

Our mission

To build homes for people who care about quality, not just price. Every detail matters, from the materials we use to the way we listen and adapt to customer feedback. We are not in it for volume. We are in it to do things right, with care, clarity and long-term commitment.

We aim to grow the company responsibly, but only as long as quality is never compromised.

Max, the customer in every meeting

Max is a teddy bear who sits in every 999 meeting. He is the customer: before we decide anything, we ask what it means for the people who will live in the house. Max is not a mascot. Max is the customer, always here, always first.

How we build

Built as if we live in it

Every detail, from construction to handover

We care about every detail of the house, from the first day on site to the day we give you the keys.

Open, connected living

Our first house in Nam Phrae was a loft where every zone was connected, so wherever you are, you can see and talk to each other. Our villas keep that idea, with more space.
