Eastleigh area projects

Many Eastleigh extensions qualify under Permitted Development Rights without full planning permission. Single-storey rear extensions up to 4m deep on detached houses or 3m on semi-detached typically qualify under PD. Eastleigh Borough Council has conservation areas in parts of Chandler's Ford, Bishopstoke and Fair Oak where planning permission is required. Some properties also have Article 4 Directions. We check your specific situation during every complimentary consultation.

Our fixed design fees are: Pre-Build Package from £1,950 + VAT (planning drawings), and Premium Plus from £4,950 + VAT (full service). Build costs in Eastleigh — paid to your contractor — run approximately £1,750–£2,500 per m² depending on specification. Use our Extension Cost Calculator for a project-specific estimate.

Eastleigh and its surrounding villages (Chandler's Ford, Bishopstoke, Fair Oak, West End) have a mix of 1930s semi-detached and 1970s–80s detached properties. Rear kitchen extensions creating open-plan kitchen-diners are the most popular project. Side extensions, garage conversions and loft conversions are also common, particularly in Chandler's Ford where plot sizes allow.

Eastleigh Borough Council targets an 8-week determination period for householder applications. Well-prepared applications in non-conservation areas often meet this target. We submit comprehensive applications that pre-empt officer queries to minimise delays and keep your project on schedule.

We cover SO50 and SO53 (Eastleigh, Chandler's Ford, North Baddesley), plus Bishopstoke, Fair Oak, Horton Heath, West End and Hedge End. We also work throughout neighbouring Winchester, Southampton and Fareham areas from our Winchester base.
