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.

Conservation areas and listed buildings
-
Maximum extension depth and height
