Kitchen Expansion and Addition in Bellevue, WA

Our team provides permit drawings and 3D layout planning, delivering genuinely larger working kitchens for homes and code-compliant structural upgrades for both residential and commercial properties. Backed by a Washington State contractor license and general liability insurance, we take on work at every scale, from a 40 square foot eating-nook bump-out to a 300 square foot great-room addition.

From setback verification and footing excavation to flashing details that hold up under Bellevue's 32 inches of annual rain, our team handles every detail. Serving Bellevue and neighboring Newcastle, Kirkland and Issaquah, we deliver disciplined scheduling and reliable, professional, beautiful results on every kitchen addition project.

Three Ways to Make a Bellevue Kitchen Bigger

Annex the room next door. The cheapest real square footage in any house is the formal dining room or an oversized utility room already under the same roof. No foundation, no roof, no setback question. Just a wall, a load path and a new layout. Plenty of mid-century homes in Lake Hills and Crossroads have that room sitting unused.

Bump out. A cantilevered or footed extension of 2 to 8 feet along the back or side wall. It buys the counter run or the banquette the old footprint could never fit. Shallow bump-outs under about 2 feet can sometimes cantilever off the existing floor joists, avoiding a new foundation entirely.

Build a full addition. 150 to 300 square feet or more on new footings, with its own roof and envelope. That is what a true great-room kitchen with an island, a walk-in pantry and a dining zone takes.

Which one fits comes down to your lot, your setbacks, your foundation and the direction your floor joists run. We answer all four on the first visit.

Permits, Setbacks and What Bellevue Will Approve

Any addition that changes the building footprint requires a City of Bellevue building permit, and structural work gets plan review rather than an over-the-counter approval. Expect several weeks, longer in busy season.

Before drawings, we check four things:

1. Setbacks. How close the new wall can sit to the side and rear property lines under your zone.
2. Lot coverage. Bellevue's density runs about 4,530 people per square mile, and lot sizes in Newport, Woodridge and Bridle Trails vary enough that coverage limits bind on some properties and not at all on others.
3. Critical areas. Steep slopes, streams and wetlands are common near Cougar Mountain, Lakemont and the West Lake Sammamish corridor, and can trigger a geotechnical review.
4. Existing structure. Foundation condition, joist direction and span, panel capacity, and whether the roof accepts the tie-in.

If any answer is a hard no, you hear it on the first visit, not after paying for a design.

Designing the Larger Kitchen

More square footage is not automatically a better kitchen. A room that grows without a plan just adds walking distance between the sink and the range.

Base cabinets stay 24 inches deep at 34.5 inches high, wall cabinets run 12 inches deep at 30, 36 or 42 inch heights, and widths step in 3 inch increments. The new wall length decides whether you get clean full-height runs or a row of fillers. Aisles want 42 to 48 inches for one cook, 48 or more for two. Windows in the new wall have to clear the backsplash and the uppers, which is a drawing decision, not a field decision.

We model it first. Kitchen design and 3D planning puts the expanded room on screen with real cabinet sizes before the footing is poured. Most clients change the plan twice at that stage, which is the point.

Related Services

Most clients also want the wall between the new space and the living room gone, which is an open concept kitchen remodel. The kitchen inside the new shell is a full kitchen remodel, or a luxury kitchen remodel at the higher tiers. Adding a powder room or second bath in the same build is covered on our bathroom additions page, and the new island and counter runs are kitchen island installation and countertop replacement.
