Room Additions in Tarzana.
The larger lots across Tarzana, especially up in the hills, often leave room to add square footage without crowding the property. We design and build additions that match the existing ranch or traditional architecture, from a primary suite to a full second story. Above the boulevard, we handle the grading and hillside permit steps that come with building on a slope. Fixed pricing, our own crews, and permits managed from plans through final inspection.
Additions that look original, not bolted on.
A great addition disappears into the home. We manage structural engineering, permits, and foundation work, then match rooflines, finishes, and details so the new square footage feels seamless, on a fixed price with your timeline protected.
Many Tarzana homes are ranch-style properties on generous lots, where opening up a floor plan or adding an ADU pays off. Where a home sits above Ventura in the hills, we manage the grading and permit steps that come with building on a slope.
Working in Tarzana
Tarzana runs from ranch homes and newer builds in the flats to large gated properties south of Ventura Boulevard. Lot sizes here support ambitious projects: whole-home remodels, big kitchen and great-room combinations, and detached ADUs that would not fit on smaller Valley parcels.
The City of Los Angeles issues permits in Tarzana, with hillside requirements on some southern parcels. We handle the full process, from plans and engineering through final inspection, on a fixed itemized price.
