San Diego · Est. 2015
A residential studio led by Mark T. House, designing considered custom homes across coastal California — from La Jolla to Rancho Santa Fe.
Founded in 2015 by Mark T. House, the studio draws on more than thirty years of residential practice in Southern California. Each commission begins with the site: its orientation, its climate, its restraints, and the particular life a client hopes to build on it.
Our work spans new construction, thoughtful renovation, and fully considered interiors — from coastal residences in La Jolla and Del Mar to estate homes in Rancho Santa Fe.
Each project starts by listening — to the property, its orientation and grade, the way the coastal light moves through the day, and the daily rhythms of the people who will live there.
From that reading, a design begins to take shape: a plan that belongs to its ground, a palette drawn from local materials, and rooms tuned to hold the ocean, the canyon, or the ranch beyond.
Reading the ground first.
Stone, wood, plaster, glass.
Every room oriented with intent.
The California threshold.
An 8,500-square-foot coastal residence organized around a fifty-foot spine wall. Two fifty-foot sliding glass walls open the main floor to the Pacific, dissolving the line between interior and terrace.
Every commission is unique, but each moves through a considered sequence — from the first site visit to the day a family moves in. A brief overview of how we work together.
Meet, visit the site, and share the vision.
Program, site research, and design inspiration.
Initial plans, massing, and material palette.
Refined drawings, 3D model, consultants.
Permit-ready set, engineering, selections.
Agency review and contractor coordination.
On-site oversight of design intent.
Your family moves in.
