Layout change
What changes when the kitchen layout changes
Same footprint and new layout are not two points on a cost scale. They are two different jobs, and what separates them is not the drawing — it is the number of building systems that have to be re-run. This page takes a proposed change apart into the individual moves it forces, so each one can be argued with separately.
Your proposed layout, and what it drags behind it
Derived scope class
Structural reconfiguration
Removing a bearing wall makes this a structural job that happens to contain a kitchen. The beam, the load path, the drawing and the framing inspection all sit ahead of the finish decisions, and none of them can be compressed by spending more on cabinets.
Aisle check The tightest aisle is 34 inches, under the 36 inches this tool uses as its own lower threshold; check that an open dishwasher or oven door still leaves room to pass.
Work triangle check 28.6 feet of walking between the three work centres is above the 26-foot total this tool uses as its own rule of thumb; a long layout can suit a room with two cooks and two zones.
These two checks use our own rule-of-thumb thresholds (a 13 to 26 ft triangle total; aisles under 36, 42 and 48 in), not a published standard.
Each move, and what it brings with it
| System | What it drags along | Stops work? | Note |
|---|---|---|---|
| Sink waste and vent | Plumber, Floor or ceiling opening, Rough plumbing inspection | Yes | Its cost is hard to predict before the floor is open. |
| Range or cooktop circuit | Electrician, New home run to the panel | Yes | A 240-volt circuit takes its own breaker pair; the cable and how it may be extended are set by your electrician and code. |
| Refrigerator receptacle and water line | Electrician, Plumber for the ice maker | No | Easy to forget, which is how a finished kitchen can end up with a water line run across a toe kick. |
| Range hood duct and exterior termination | Carpenter, Roofer or siding repair, Exterior patch and paint | No | Moving the hood means a new hole through the building envelope and a repair to the old one. The exterior work may be quoted by someone who was not in the kitchen. |
| Load-bearing wall removal | Framing carpenter, Engineered beam, Temporary shoring, Stamped drawing, Framing inspection | Yes | A bearing wall needs a beam and a load path down to the foundation; ask your building department whether it requires an engineer’s detail before framing is signed off. |
| Flooring footprint | Flooring installer, Transition detail to adjoining rooms | No | Extending the floor into an adjoining room can leave that room’s floor not matching; decide it early. |
Read that table as a menu rather than a verdict. Each row is a decision somebody made, and each row can be reversed independently. Turning off one toggle above and watching the trade count fall is a quick budget conversation to have before anything is ordered.
The two geometry checks that cost nothing to pass
The walking distance between the three centres
| Leg | Distance |
|---|---|
| Sink to Range | 8.5 ft |
| Range to Refrigerator | 9.3 ft |
| Refrigerator to Sink | 10.8 ft |
The three work centres are the sink, the cooking surface and the cold storage, and kitchen tasks are trips between them. The total walking distance is free to optimise on paper and hard to change once the plumbing is in the floor.
The aisles
Aisle width is hard to change once cabinets are set. An island four inches narrower is invisible in a drawing and costs nothing to change at that stage.
The case for keeping the footprint
A same-footprint kitchen is not a compromise. It is the version where the money goes into what you touch daily instead of into what is behind the drywall.
- The trades come once instead of twice, which removes the return visits.
- Fewer inspections sit on the critical path, so the schedule leans more on lead times you can see.
- The demolition stops at the surfaces, so less of the building is opened to surprises.
- Money not spent moving services can go to cabinet grade instead.
If the layout does have to change, the single decision to check first is whether the sink moves. Work out whether the drain can physically get there before accepting a price for it, because its cost is hard to predict in advance.
