Kitchen Extensions

A kitchen extension is as much a services and layout project as a building project. Drainage, extraction, electrics and appliance positions should be resolved before the shell is finished.

UK house detail relevant to kitchen extensions

Design the kitchen before fixing every opening

A door in the wrong place can remove a run of units. A rooflight can clash with tall cabinets or extraction. Put the kitchen layout over the architectural plan early.

Drainage affects islands and sinks

Moving a sink across the room may require a long waste run with adequate fall. Islands with sinks or dishwashers can need drainage cast into or routed below the floor.

Large openings change heating and acoustics

An open kitchen, dining and living room may be attractive on plan but needs thought about heating zones, noise and where people actually sit. Keeping a short wall or separate utility room can help.
