Overview

Ultra sits on a hillside plot with an uninterrupted line of sight to the Gulf of Thailand. The brief was simple to say and difficult to deliver: let the sea be the only ornament the house needs.

Every room steps down toward the view. The roofline stays low and flat, the walls disappear behind full-height glazing, and the rooftop terrace — lawn laid flush to its concrete edge — reads as an extension of the horizon rather than a feature added to the building.

Architecture

A cantilevered concrete frame carries the upper floor out over the slope, freeing the ground level for uninterrupted glazing. Sightlines were modelled from every seating position in the house before a single wall was drawn, so the architecture works in service of the view rather than competing with it.

Interior Design

Interiors stay quiet on purpose — a restrained palette of white, stone and warm timber, so that light and the view carry the room. The bathrooms in particular were treated as extensions of the landscape: a freestanding tub set against full-height glass, framed by the same hillside it overlooks.

Construction

Built in cast-in-place concrete to hold the long cantilevers without visible support, with the rooftop terrace waterproofed and turfed as a true outdoor room rather than an afterthought. Our site team supervised the build end to end, coordinating structural, glazing and landscape contractors under one schedule.

Completion

Ultra was handed over as a complete, furnished residence — architecture, interiors and landscape delivered as a single body of work, by a single team, on a single schedule.
