Architecture & Interior Design in Brentwood
Matter is a Los Angeles architecture and interiors studio designing homes across Brentwood — from the flats below San Vicente to the canyons of Mandeville, Kenter, and Sullivan. We build houses meant to last: private, generous, and rooted in how a family really lives.
Brentwood asks for quiet confidence. Lots range from the walkable flats to steep canyon sites, and the best houses here don't announce themselves. We begin every project with a Discovery Session that translates how you live into a written Concept Brief, before a single line is drawn. What follows is a home shaped to its site — private, full of light, and detailed in materials chosen to age well.
On canyon and hillside lots we work fluently with grading, geology, and the city's Hillside Ordinance and fire requirements, interpreting them early so the design moves forward whole. Whether the language is traditional or modern, the aim is the same: a home that belongs to its street and holds its worth in how well it is made.
Every decision earns its place. Plans, materials, and daylight are drawn, tested, and refined; then we see the work through construction, detailing, and oversight — until the space is real, resolved, and yours to live in for decades. We are not designing houses to sell in a year, but homes for generations, meant to hold a family's life and leave something lasting behind.

Do you design homes throughout Brentwood?
Yes — from the flats below San Vicente to the canyons of Mandeville, Kenter, and Sullivan, including hillside and view lots.
Do you work with canyon and hillside lots?
Yes. Canyon sites carry their own grading, geology, and fire requirements, and we design and document with the Hillside Ordinance in mind from the first sketch.
Do you design traditional or modern homes?
Both. We work in whichever language suits the street and the way you live — the priority is a home resolved down to the detail and built to last.
