What We Build

Built to the last detail.

The full range of a Westside residence, from the stair you photograph to the steel you never see.

What we build
A custom home at this level is not one project. It is seven disciplines holding the same line.
The architecture, the interiors, the wellness suites, the life inside, the technology, the grounds, and the engineering that carries all of it, each coordinated from the first slab, mocked up before it is committed, and documented as it goes in.

I · Architecture & Design

Architectural Statement

The gestures a house is remembered by.
The seen architecture: the stair you photograph, the wall of glass, the ceiling that becomes a source of light. Each gesture is mocked up at full scale before anything is committed.
01

Exterior Architecture & Stone

Cut limestone and antique brick set the street elevation, dry-laid and sequenced so the masonry reads as one piece.

Walls of Glass & Indoor-Outdoor Living

VII · The work you don't see

Engineering & Execution

Where the envelope is earned.
Hillside shoring, structural concrete and steel, the waterproofing membranes, and the MEP plant behind the walls, sequenced, coordinated, and documented before it disappears behind the finish.
01

Site, Shoring & Foundations

Excavation, soldier-pile shoring, and retaining systems that make a hillside lot buildable, through geotechnical review and deputy inspection.
