Full-service general contracting,
from foundation to final detail.
Whether you're building from a blank lot or reimagining the home you love, our in-house team manages every phase — design, permitting, construction, and finish — under one accountable roof.
Custom Homes
We build new construction from the lot up — single-family residences, hillside estates, and luxury Peninsula homes designed in close collaboration with you and your architect. Every K&M custom home is led personally by a principal, framed by trusted subcontractors we've worked with for years, and delivered on a schedule we publish before we break ground.
- 3,500 – 8,000+ sq ft new construction
- Hillside, view-lot, and complex foundation builds
- Architect-led or design-build engagements
- Smart-home, structured wiring, and EV-ready integration
$2M – $6M+ typical project range
Final pricing depends on scope, finishes, and site conditions. We share a detailed budget after the consultation walkthrough.
Remodeling
From a single chef's kitchen to a full down-to-the-studs renovation, we approach remodels with the same rigor as new construction. We protect what matters about your existing home — original millwork, mature landscaping, neighbor relationships — and rebuild around it with materials and finishes that match the level of the rest of the Peninsula.
- Kitchen and primary-bath remodels
- Whole-home gut renovations
- Historic home restorations
- Structural reconfigurations and load-bearing work
$250K – $1.5M+ depending on scope
Final pricing depends on scope, finishes, and site conditions. We share a detailed budget after the consultation walkthrough.
ADUs
ADUs are the fastest-growing residential category on the Peninsula, and the rules change constantly. We handle the SB-9 / SB-1069 permitting maze, the design review process with your city, and the construction itself — delivering a finished, occupancy-ready unit that integrates with your main home's architecture and landscape.
- Detached ADUs from 600 – 1,200 sq ft
- Garage conversions and JADUs
- Multigenerational guest suites
- Permitted rental units
$220K – $600K typical, all-in
Final pricing depends on scope, finishes, and site conditions. We share a detailed budget after the consultation walkthrough.
Additions
An addition that reads as 'added on' is a failed addition. Our work blends the new construction so completely with the existing home — rooflines, window proportions, materials, interior trim — that nobody can tell where the old ends and the new begins. We've added second stories to single-stories, extended footprints, and connected detached structures.
- Second-story additions (1,000 – 2,500 sq ft)
- Single-story extensions and bump-outs
- Connecting detached garages or studios
- Roof reframing and dormer additions
$300K – $900K typical
