How Much Does A Kitchen Extension Cost?

This is usually the first question our customers ask. To help answer it, we’ve created a simple and cutting-edge extension cost calculator. Extension building costs can vary, especially in London. Hopefully, our cost calculator will provide some much-needed clarity.

Our tool makes it easy for you to see exactly what extensions are available to you, and what cost factors are included in your final quote. We’ve also provided 3D models of how your extension would look, bringing your new vision for your home to life.

House type

Select from below options

Detached House Extension North London
Detached

Best for: Maximum space. Detached homes allow for significant rear and side wrap-around extensions without shared wall constraints, perfect for creating large open-plan kitchen-diners.

 

Semi-detached Extension Barnet
Semi-detached

Best for: Side-return or rear projects. These homes often have side access, making construction easier and allowing for bright, airy extensions that flow into the garden.

 

End of Terrace Extension Enfield
End of terrace

Best for: Wrap-around potential. Similar to semi-detached, the extra side space is ideal for expanding the kitchen width-ways while maintaining the home’s character.

 

Terraced Flat Back Extension Highgate
Terraced – Flat Back

Best for: Full-width rear extensions. For homes without an outrigger, a 3m-6m rear extension can transform a cramped kitchen into a modern family hub.

 

L-Shaped Extension Crouch End
Terraced – L Shaped

Best for: Victorian & Edwardian homes. The L-shaped wraparound is the premier choice for North London terraces, adding massive value and square footage.
