HOME ADDITIONS IN KIRKLAND

ADDITION TYPES THAT WORK HERE

Primary suite additions

are the most common request, usually pushed to the rear where the lot allows and detailed with a walk-in closet and a proper bath.

Second-story additions

over the ubiquitous single-level ranch. This is heavy structural work — the existing first floor needs a new load path, new footings under new posts, and a rebuilt stair — but it doubles the house without consuming a square foot of yard.

Kitchen and family room expansions

that open the rear wall onto a covered patio with heat and screens so it gets used nine months a year.

ADUs and detached studios

for rental income or multigenerational living, subject to the current Kirkland rules on size and parking.

**Mudroom and laundry bump-outs** off the garage, which is the least glamorous and most appreciated addition on the list.

THE SEAM IS EVERYTHING

An addition should not announce itself. Roof pitch matches, siding profile and coursing match, window head heights align with the existing openings, and the floor is dead level at the transition.

Inside, we remove the old exterior wall entirely and carry one continuous ceiling plane rather than leaving a header drop that reads as a scar.

Engineering and Permit Reality

Additions require stamped structural calcs, and in Kirkland that includes connection details at the existing structure and often a geotech review on sloped sites. We coordinate the engineer and own the submittal. Review takes weeks, not days, and we build that into the schedule rather than pretending it away.

Living On-Site

Most families stay during an addition. We hang plastic at the work boundary, run a HEPA unit in the occupied zone, protect the floor on the access path, and hold a consistent start time so the household can plan around it.

What It Costs

Additions price by the square foot of new conditioned space plus the structural work at the tie-in, and the tie-in is where budgets surprise people. A rear suite on a slab is one number. The same square footage as a second story is another. We build the line-item budget in pre-construction so you see the split before you commit.
