What we build in Tarzana and Los Angeles

The biggest projects start from the ground. Our custom home builders take a new house from plans and permits to final inspection, including tear-down and wildfire rebuilds. For a second home on the same lot, an accessory dwelling unit adds a rentable unit with its own kitchen, bath and entry. When the floor plan itself is the problem, a room addition buys square footage without a move.

Inside the house, a kitchen remodel is where families spend the most time and the largest share of the budget. Close behind it, a bathroom renovation returns the most comfort per square foot, especially a primary bath. Owners who would rather do it once book a whole home remodel and take every trade at once.

Not every job is a gut renovation. Flooring, plaster and carpentry fall to our general remodeling crew. Daylight, security and energy bills all improve with new windows and doors. Outside, a backyard remodel turns unused yard into usable rooms. Fresh exterior painting protects stucco and trim from Valley sun. To change how the house reads from the street, start with a front facade remodel.

Master in Design has been transforming homes across the San Fernando Valley since 2012. We are a licensed general contractor (CSLB #979219) based in Tarzana, California, specializing in full-service residential remodeling, from concept and permitting through construction and finish carpentry. Unlike firms that subcontract every trade to the lowest bidder, we maintain a core crew of in-house craftsmen supported by a vetted network of electricians, plumbers, and structural engineers we have worked alongside for over a decade.

Homeowners in Tarzana, Encino, Woodland Hills, Sherman Oaks, Studio City, Calabasas, and Hidden Hills choose us because we deliver one thing that is surprisingly rare in remodeling: a single point of accountability. When you call with a question, the person who answers knows your project, your timeline, and your budget. No call centers. No runaround.
