Split-Level Kitchen Remodel Ideas and How to Plan Them

What makes a kitchen in a split-level house different to remodel?

A split-level house divides its floors into staggered levels joined by short flights of stairs. The kitchen usually sits on the main level beside the dining and living rooms, with a bedroom level half a flight up and a family room half a flight down. Walls often close the kitchen off from those stairs and rooms.

That shapes four decisions. Which wall comes out and what it carries. What happens at the edge of the stairs once the wall is gone. How the floor meets the levels above and below. And how much light reaches a kitchen that may have one window. Settle all four in the drawings before demolition, because each one changes the price and the permits.

How do you open up a split-level kitchen to an open concept living room?

An open concept split-level kitchen removes or widens the wall to the living or dining room, once you know what the wall carries. A wall that holds up the floor or roof above needs a new beam or header and an engineer's design. Our Cost of a Kitchen Remodel in the Greater Seattle Area guide puts it plainly: "A load-bearing wall needs a beam, engineering and a building permit." A non-structural wall is a simpler job.

Three of our own jobs show the range. In our Split-Level Whole Home Remodel with a Marble Fireplace, temporary steel posts carried the load while walls on the main floor came out and new framing went in. The short flights of stairs between the levels were rebuilt to match. The whole house took about seven months, November 2021 to June 2022, and cost about $200,000 for the structure, kitchen, two bathrooms, floors, paint, railings and fireplace. In Edmonds in 2021, we took the wall between a kitchen and dining room back to the studs and framed a new header over a much wider opening, for about $50,000. In Shoreline in 2022, a beam went in under a change order, and a wide opening with a peninsula now connects the kitchen to the living room. The job cost about $70,000.

What does the code require where a split-level kitchen opens to the stairs?

A guard, where the stairs or landing beside the opening sit more than 30 inches above the floor below. The 2021 Seattle Residential Code, Chapter 3 (read October 2026) sets the rules:

• Where a guard is needed. Section R312.1.1 (page 3-54) requires guards on open-sided walking surfaces, stairs and landings "more than 30 inches (762 mm) measured vertically to the floor or grade below at any point within 36 inches (914 mm) horizontally to the edge of the open side."
• How tall. Section R312.1.2 sets 36 inches, and "not less than 34 inches" on the open sides of stairs, measured from the line of the nosings.
• How open. Section R312.1.3 bars openings that "allow passage of a sphere 4 inches (102 mm) in diameter." On the open side of stairs the limit is "4-3/8 inches (111 mm)" (exception 2).
• Handrails. Section R311.7.8 (page 3-52): "Handrails shall be provided on not less than one side of each flight of stairs with four or more risers." Section R311.7.8.1 sets their height at 34 to 38 inches.

So a split-level opening ends in a half wall, a railing or glass, and the choice belongs in the design. The split-level whole home job above got a black cable stair railing.

Do you need a permit to move a wall in a split-level kitchen?

For a loadbearing wall, yes. Section R105.2 item 1 of the 2021 Seattle Residential Code, Chapter 1 (page 1-7, read October 2026) exempts minor work of $6,000 or less in six months, then adds: "Such repairs and alterations shall not include the removal, reduction, alteration or relocation of any loadbearing support."

How do you get more light into a split-level kitchen?

Borrow it from the room you open to. When the living room beside the kitchen has more windows, a wider opening shares their light. In our Shoreline kitchen, the new opening means the living room is visible from the sink.

Then layer the electric light. Our Basic kitchen tier includes recessed and under-cabinet lighting. Mid-Range tiers add a lighting plan, and our Refresh Luxury tier adds a lighting plan with dimmers. Put task light over every work surface: pendants over an island or peninsula, and strips under the wall cabinets so the counters are lit where you cut and cook.

Which split-level kitchen floor plan fits: peninsula, island or L-shape?

It depends on the width you gain. A peninsula fits where the old wall stood and marks the edge of the kitchen without blocking the view; the Shoreline kitchen uses one at its new opening. An island needs room on every side. The National Kitchen and Bath Association recommends work aisles of at least 42 inches for one cook and 48 inches for two in its Kitchen Planning Guidelines (PDF page 6, read October 2026). A two-level island adds a prep counter on the kitchen side and a lower dining counter on the living side.

Keep the sink, range and refrigerator in a short work triangle, and keep stair traffic out of it. Storage carries the rest. Our Lynnwood kitchen kept its L-shaped footprint and added a lazy Susan in the corner, a pull-out spice rack and recycling pull-out by the range and a full-height pantry, for about $50,000 in early 2024. Running wall cabinets to the ceiling adds more; if a box sits above them, read What Is a Soffit in the Kitchen?

How do you handle flooring between the levels of a split-level kitchen?

Run one floor across the whole level, and finish the stairs to match. Our Kitchen Remodeling Across the Greater Seattle Area service covers tile, luxury vinyl plank and hardwood. Our flooring service adds stair treads and nosing to match the new floor, and transition strips or flush thresholds where one floor meets another. One floor through connected rooms also saves transitions and cuts.

Our jobs show three ways to do it. In Lynnwood, one light gray plank floor runs through the kitchen and dining area. In Edmonds, the herringbone plank floor went down wall to wall before the cabinets were set on it. In a Seattle condo, the owner kept the original stone tile in the kitchen, and the living room got a new wide plank wood floor. That job ran from 2022 to early 2023 and cost about $90,000. Our Large Mid-Range tier includes a floor into adjoining rooms.

How much does a split-level kitchen remodel cost?

A split-level kitchen remodel costs $35,000+ for a refresh in the same layout and $120,000+ once a non-structural wall opens to the dining or living room. Removing a loadbearing wall starts at our Large Luxury tier, $225,000+, because it needs a beam, engineering and a building permit. These starting prices come from our pricing guide, updated October 2026. For a small room, read How Much Should a 10x10 Kitchen Remodel Cost?

How do we plan and build a split-level kitchen remodel?

We walk the kitchen and the stairs with you, measure both levels and note which walls carry load. Our designer lays out the kitchen and shows it to you in 3D. We price every line in writing, including the beam, the guard and the floor at each level, and file the permits the scope needs. One project manager runs the structure, rough-ins, inspections and finishes, and walks the finished kitchen with you at handover.
