Planning a kitchen in an extension.

An extension is the best chance to get the kitchen layout exactly right, because pipes, cables and ducting can go wherever the plan needs them. The trick is planning the kitchen early and ordering the cabinets at the right time.

1 · Plan early

Plan the kitchen before the builder starts.

Decide the kitchen layout while the extension is still on paper. Your builder, plumber and electrician need it to put services in the right place. Send us your architect's drawings and we can plan and price the cabinets from them, then confirm sizes once the room is built.

  • Islands need water, waste and power brought up through the floor before the screed goes down.
  • Sinks and dishwashers need waste runs with enough fall, so check where the waste can leave the building.
  • Extractors need a ducting route to an outside wall or through the roof.
  • Sockets and lighting should be placed for the worktop run, under-cabinet lights and appliances.
  • Rooflights and windows decide where tall units and wall cabinets can go.

2 · Measure the finished room

Measure after plastering, not from the plans.

Rooms are never built exactly to the drawing. Once the walls are plastered and the floor is screeded, measure the actual room using our measuring guide and send us the final sizes. We update the drawings and you approve them before we make anything.

Underfloor heating? Tell your fitter. Cabinet legs and plinths sit on the finished floor, and fixings must avoid the pipes.

3 · Order at the right time

Time the order with the build.

Kitchens take us 2 to 3 weeks to make once the drawings are approved and the deposit has cleared. Most people order when the extension is watertight and plastered, so the cabinets arrive when the room is dry and the floor is down.

Plaster and screed need time to dry before cabinets go in. Ask your builder when the room will be ready for the fitter, and plan the delivery for then.

4 · Open-plan living

Match the rest of the room.

Extensions are often kitchen, dining and living space in one. Because we make every cabinet to measure, the same board and doors can carry on into a pantry, utility, boot room, home office or media wall, so the whole space matches.
