THEVA Construction: technology partner to a Koh Samui villa builder

THEVA Construction builds hospitality-grade villas on Koh Samui. Its current project, THEVA Horizon Samui, has sixteen sea-view villas and a clubhouse above Lipa Noi, and the company is led by managing director Mathias Valon within Theva Group, whose chief executive Peerawat Hansirikul also leads RoomQuest. Opsian is the technology partner to both.

A villa in a hybrid hospitality-and-property model has three kinds of person walking through its door: an owner, a renter and a hotel guest. The technology brief follows from that. The building needs the same identity, access and service layer a hotel has, specified into the project rather than retrofitted after handover.

Opsian runs self check-in at the Theva Koh Samui property. An arriving guest finds their booking, scans a passport or ID card, takes a live selfie and receives a door code in their own language, on the same identity layer that runs across the RoomQuest portfolio. Staff oversee arrivals from one dashboard and step in only when a case needs a person.

Because the identity layer prepares the guest registration record Thai immigration requires, a villa that is sometimes a home and sometimes a hotel room can meet the same obligations as a hotel without a front desk on site.

Opsian is building the THEVA app presented at theva.construction: the owner and resident app for THEVA's hybrid hospitality-and-property projects on Koh Samui. It is designed to put sales, unit status, rental returns and the services of the property in one place, so an owner abroad can see what their villa is doing and a resident can ask for what they need without a phone call.

Opsian chief executive Patrick Che serves as THEVA Construction's Chief Technology Officer. In September 2026 THEVA Construction signed sales and marketing partnerships for THEVA Horizon Samui with Conrad Properties, Samui Island Realty and FazWaz.
