Types of House Extensions We Design in Basingstoke

Rear Extensions

The most popular choice for Basingstoke modern estates. Opens your kitchen or living area into the garden, creates open-plan family space. Most fall under Permitted Development — no planning needed.

Kitchen Extensions

Dedicated kitchen extension design for Basingstoke homeowners. From 12m² utility additions to 40m² open-plan kitchen-diners with bi-fold doors and roof lanterns.

Two-Storey Extensions

Maximum space gain — add a bedroom above and a larger kitchen below. Basingstoke's semi-detached housing stock is ideal for this. Often the best value per m² of added space.

Side Return Extensions

For Basingstoke terraced and semi-detached properties — fill in that narrow side gap to create a wider kitchen or utility room without touching the garden.

Single-Storey Extensions

Single-storey rear and side extensions for Basingstoke homes. Simpler structurally, faster to build, and many qualify as Permitted Development without planning permission.

Loft Conversions

Convert your Basingstoke loft into a bedroom, home office or bathroom. Most Basingstoke properties have suitable roof space. Dormer and Velux options available.
