Flat Land in Woodland Hills: Survey, soils report, grading and permits. We stake the footprint and get the City of LA sign-off before a single shovel goes in.

New Foundation: Engineered footings, rebar and anchor bolts, inspected and poured. Hillside, slab or raised, we build the base everything else sits on.

Structural Framing: Walls, floor joists and roof rafters go up to the engineer's plan, with shear walls and hold-downs for Southern California seismic code.

Windows and Doors: Sheathing, house wrap and flashed openings, then the black-framed windows and the pivot entry door. The house is now sealed against the weather.

Roofing: Underlayment and a standing seam metal roof, installed and flashed by our own crew. Built for heat, Santa Ana winds and fire zones.

Exterior Finishes: Smooth stucco, oak cladding, driveway and drought-tolerant landscaping. The outside is done, and it looks like it belongs on the street.

Step Inside: From the curb to the front door. Every detail you touch daily, the hardware, the threshold, the light, is planned before we build.

Open Living Space: Double-height ceilings, white oak floors and floor-to-ceiling glass. Electrical, HVAC and insulation are all hidden behind finish-grade drywall.

L-Shaped Chef's Kitchen: A big L-shaped layout around a waterfall-stone center island. Custom cabinetry, paneled appliances and lighting we lay out with you.

Up the Stairs: A floating oak staircase with frameless glass rail. Structural steel and finish carpentry, built in-house to tight tolerances.

Master Bathroom: Marble slab walls, a freestanding tub and a walk-in shower. Waterproofed, tiled and plumbed by our own team. High-end finish, done right.
