Single-Storey Extensions

Perfect for expanding your ground-floor living space.
Common uses include:

  • Open-plan kitchen/diners

  • Larger living rooms

  • Utility spaces

  • Downstairs bathrooms

  • Garden-facing family rooms

A single-storey extension offers great flexibility and often doesn’t require full planning permission.

Increase both your living space downstairs and your bedroom space upstairs in one build.
Ideal for:

  • Growing families

  • Master bedrooms with ensuite

  • Additional children’s rooms

  • Bigger kitchen and dining layouts

A cost-effective way to add major value to your Chichester property.

Side & Wraparound Extensions

Make use of unused outdoor space to improve the layout of your home.
Great for:

  • Kitchen extensions

  • Home offices

  • Playrooms

  • Utility areas

  • Storage or boot rooms

These extensions are especially popular in terraced and semi-detached homes around Chichester.

Wrap-Around Extensions

A combination of side and rear extensions that create a spacious, open-plan area.
Ideal for homeowners looking for a dramatic change and maximum usable space.
