Writing a Kitchen Renovation Brief for Your Architect

Why the Brief Matters More Than the Pinterest Board

A kitchen is the most services-intensive room in a house: water, waste, gas, electrics, and ventilation all converge in a space that must also function beautifully. Handing your architect a folder of saved images is a starting point, not a brief. A proper written brief translates your preferences into technical requirements, reduces design iterations, and keeps costs under control. For homeowners in Hampstead and the surrounding NW postcodes — where period properties often have quirky floor plans and solid masonry walls — getting the brief right is especially important.

Layout Options to Consider

Before your architect puts pen to paper, think about how you cook and socialise. A galley layout suits narrow Victorian side returns and maximises worktop length. An L-shaped arrangement works well in square rooms and allows a small dining table within the kitchen. An island layout is the most popular choice in rear-extension projects, but it demands a minimum footprint of roughly four by five metres to avoid feeling cramped. Specify whether you want the hob or the sink in the island, because this determines where extraction ducting and waste pipes must run — both of which affect structural and building-control considerations.

Services Relocation

Moving a kitchen sink more than a metre or two from its current position usually means re-routing the soil stack or installing a macerator pump. Gas supply relocation for a range cooker requires a Gas Safe registered engineer and may need a longer pipe run if the metre is at the front of the house. Discuss these constraints with your architect early; they will affect the layout far more than tile choices. If you are combining a kitchen project with a rear extension in areas like Belsize Park or Maida Vale, the structural opening between old and new is the ideal moment to upgrade the soil connection.

Ventilation and Extraction

Building Regulations require mechanical extraction in every kitchen — either a cooker hood ducted to the outside or a whole-room ventilation system. For induction hobs, downdraft extractors are popular but less effective with high-heat cooking. Specify your preferred cooking style so the architect can size the ducting correctly. In conservation areas, the external grille or outlet must be discreet; Camden has refused applications where extraction vents were visible from the street.

Lighting Planning

Kitchen lighting divides into three layers: ambient (ceiling downlights or pendants), task (under-cabinet LED strips over worktops), and accent (display lighting inside glass-fronted units). Include your preferences in the brief so the architect coordinates with the electrician at first-fix stage rather than retrofitting later at twice the cost. Where a kitchen extends into a new rear extension, rooflight placement becomes a critical part of the lighting design — natural light can reduce reliance on artificial sources during the day.

Materials and Budget

Specify your worktop material preference — natural stone, engineered quartz, or timber — because each has different structural support requirements. Cabinetry ranges from flat-pack at around three hundred pounds per linear metre to bespoke joinery at two thousand or more. A useful rule of thumb: allocate roughly fifteen to twenty per cent of the total kitchen-extension budget for the kitchen fit-out itself, and share this figure openly with your architect so the building design and the kitchen specification develop in step.

Pulling Your Brief Together
