Why Extend Your Kitchen into the Garden?

Extending your kitchen into the garden is one of the most popular home improvements in London. With limited internal space, homeowners are choosing rear and side extensions to create larger, open-plan kitchens that connect seamlessly with outdoor areas.

A well-designed kitchen extension not only improves daily living but can significantly increase property value.


Popular Types of Kitchen Garden Extensions in London

Rear Extensions

Rear extensions are ideal for terraced and semi-detached London homes. They extend the kitchen straight into the garden, creating space for dining areas, islands, and family seating.

Side Return Extensions

Common in Victorian and Edwardian properties, side return extensions utilise unused alley space to widen the kitchen while maintaining garden access.

Wraparound Extensions

A combination of rear and side return extensions, wraparound layouts maximise kitchen size and allow for dramatic design features.


Planning Permission and Building Regulations

Many kitchen extensions in London fall under permitted development, but this depends on property type, location, and extension size.

Key Planning Considerations

  • Conservation areas and listed buildings

  • Maximum extension depth and height

  • Party wall agreements

  • Impact on neighbours and light

Building regulations approval is always required and covers:

  • Structural integrity

  • Insulation and energy efficiency

  • Drainage and ventilation

  • Electrical and plumbing safety

DecoReno manages the entire compliance process from design through to completion.
