House Extensions in Basingstoke — What You Need to Know

Basingstoke sits within the Basingstoke and Deane Borough Council area, which processes planning applications in line with national permitted development rights but applies its own local design guidance, particularly within conservation areas and on post-war estates where proportionality and material match are closely scrutinised.

The good news: the majority of single-storey rear extensions in Basingstoke fall within permitted development thresholds and do not require a full planning application. Our team will confirm your permitted development position at the outset — free of charge — so you know exactly what route your project will take before you commit to anything.

For projects that do require a planning application, Basingstoke and Deane's planning portal allows online submission, and our Pre-Build and Premium packages include full application management on your behalf.

Our Services in Basingstoke

House Extensions Basingstoke

Single-storey rear extensions, double-storey extensions, wraparound extensions, kitchen extensions, orangeries, and open-plan reconfigurations. We produce all planning drawings and building regulations packages in-house on a fixed fee.

Loft Conversions Basingstoke

Dormer loft conversions, Velux loft conversions, and hip-to-gable conversions for Basingstoke's large stock of 1960s, 1970s, and 1980s semi-detached and detached properties. A loft conversion typically adds a bedroom and bathroom, significantly increasing property value without losing garden space.

Garage Conversions Basingstoke

Full and partial garage conversions, including detached garages and over-garage rooms. Basingstoke has a high proportion of properties with integral garages from post-war estate developments — these are well-suited to conversion and rarely require planning permission.
