Xpert Construction & Design —
Building Trust Since 2001.

Xpert Construction & Design has been building trust alongside structures since 2001. What started as a small but dedicated operation grew into a full-service general contractor — and in 2007, we earned our General Contractor license, formalizing the expertise and standards we’d been holding ourselves to from day one.

With over two decades of hands-on experience, we serve homeowners and developers throughout the Silicon Valley region. Our reputation for exceptional work and honest communication has been built one project at a time — on time and on budget.

ADU · New Construction · Room Additions

From Site to Finished Home

Every Xpert Construction & Design project — whether an ADU, a full new construction, or a room addition — follows these seven phases from initial site assessment through certificate of occupancy.

These phases apply to
  • ADU / Granny Flats
  • New Construction
  • Room Additions

Whether you’re building a backyard ADU, adding a new wing to your home, or breaking ground on a full new construction — these seven phases are the roadmap every Xpert project follows. The process, precision, and documentation standards remain consistent across all project types.

New construction timeline factors
Square footage

Size of the home

A 1,200 sq ft home and a 4,000 sq ft home follow the same seven phases — but framing, MEP, and finishes each scale with the total footprint.

Terrain & topography

Flat lot vs. hillside

A hillside or sloped site requires additional grading, retaining walls, engineered foundations, and sometimes caissons or piers — adding weeks to early phases.

Site conditions

Access & soil type

Tight access, poor soil bearing, rock excavation, or high water tables all affect site prep and foundation timelines. Every lot is evaluated individually.

Design complexity

Custom finishes & layout

Custom cabinetry, specialty tile, vaulted ceilings, or complex roof geometry extend the finish phase. Standard layouts move faster.

NOTE – A hillside or sloped site requires additional grading, retaining walls, engineered foundations, and sometimes caissons or piers — adding weeks to early phases.
