Square footage that looks
inevitable.

Primary suite additions, second-story additions, and garage conversions in Solana Beach, Del Mar, Rancho Santa Fe, La Jolla, Encinitas, and Carlsbad.

Most additions read as additions. The roofline doesn't match. The siding meets the wrong corner. The interior trim profile changes at the threshold. From the curb, you can see where the new work begins and the original house ends.

Ours don't.

We match foundations, rooflines, siding profiles, window stiles, trim returns, and interior detailing down to the corner returns. The new square footage reads as original to the house, not as an addition that was bolted on.

(Philosophy)

A great addition is invisible. The homeowner knows where the new walls are. The trades know. The architect knows. Everyone else should walk into the room and assume it was always there.

This sounds simple. In practice it requires foundation-matching, lateral-load analysis, roof tie-in detailing, exterior material continuity, and interior trim profiles that carry through the threshold. Most additions fail in at least two of those areas, because most additions are designed by an architect who isn't responsible for executing the matching detail, and built by a contractor who didn't draw the detail.

We do both jobs, so the detail lands.

(Scope)

What we handle.

01 / 04

Primary suite addition

Bedroom, bath, and closet wing planned as a single suite. Often paired with a whole-home remodel. Foundation tie-in, roof tie-in, and material matching engineered as part of the Design Phase.

02 / 04

Second-story addition

Foundation review, lateral analysis, and framing strategy worked out before the design is locked. The existing structure has to carry the load; if it can't, the foundation work is part of the project scope.

03 / 04

Garage conversion

Attached or detached garage converted into living space, an office, a primary suite, or an ADU. Setback rules and parking-replacement requirements handled during permit packaging.

04 / 04

Material matching

Siding, trim, roof tie-ins, window stiles, interior trim profiles, paint, and finish carpentry matched to the existing home, down to the corner returns.

(Materials & specification)

Specified to the SKU.

Material continuity is what separates a successful addition from an obvious one. We typically specify:

The matching specification is locked during the Design Phase, before construction is priced.

  • SidingMatched to the existing profile, sourced from the same supplier where possible. New siding aged or pre-weathered to match the existing color.
  • RoofingMatched tile, shingle, or membrane, with tie-in detailing that hides the seam.
  • WindowsMilgard or Marvin, matched to the existing window package.
  • StuccoColor and texture matched on site, with hand-applied detailing at the new-to-old transition.
  • Interior trimBaseboard, casing, and crown profiles matched to the existing home, including return details at the threshold.
  • FlooringCarried through from the existing home, with custom transition strips at the addition boundary.
(How a project starts)

Four steps, one team.

01 / 04

Discovery Call

A complimentary phone consultation. We talk about the addition type, the lot, the existing structure, and the timeline. We pull up the parcel during the call.

02 / 04

Design Consultation

A $250 on-site walkthrough with our principal. We walk the proposed addition footprint with you, look at the structural conditions, and confirm whether the existing house can carry the new work.

03 / 04

Design Phase Contract

Site plan, foundation strategy, structural analysis, floor plans, elevations, material-matching specification, and permit package. Six to twelve weeks depending on scope.

04 / 04

Construction Contract

Permits, foundation work, framing, exterior tie-in, MEP, drywall, finish carpentry, paint. The crew is the same crew that drew the project.

(Common questions)

Before you call.

  • How long does a home addition take?

    Eight to fourteen months from kickoff including the Design Phase. The variables are foundation work and roof tie-in, both of which extend the schedule on second-story additions. Permit timelines in the coastal zone add another six to eight weeks for non-ADU additions.

  • Can a garage conversion become an ADU?

    Yes. Garage-to-ADU conversions are one of the most efficient paths to permitted living space. Under California ADU law, they often qualify for reduced setback and parking requirements. The conversion can be sized for full-time occupancy or as a guest suite, depending on plumbing rough-in and exterior access.

  • Do additions need a coastal permit?

    Projects in the coastal zone require coastal permits regardless of scope. AB 462's 60-day clock applies specifically to ADUs. Other coastal-zone additions still process on standard coastal permit timelines, which typically run three to six months.

  • Will the addition match my existing home?

    That's the goal of the Design Phase. We specify siding, roofing, windows, stucco, trim, and interior finishes to match the existing home, with sample boards approved before construction. If matching isn't possible (e.g., a custom siding profile no longer in production), we'll flag the alternatives during design, not during construction.

  • Can I add a second story to my home?

    Most homes can carry a second-story addition, but it depends on the existing foundation, lateral system, and lot coverage. The structural feasibility is part of the Design Phase. If the existing structure can't carry the load, the foundation reinforcement work is part of the project scope.

  • Do you handle additions alongside whole-home remodels?

    Yes, frequently. Pairing a whole-home remodel with an addition usually reduces both cost and timeline versus running them as separate projects. The permits, trades, and structural work travel together.
