Petersfield has period terraces, cottages and family houses, with a close relationship to the surrounding South Downs landscape.

Kitchen extensions and considered loft layouts can provide more usable family space. Materials, scale and the connection to the garden inform each proposal.

Petersfield Extension Design FAQs

Many Petersfield extensions can proceed under Permitted Development Rights — single-storey rear extensions up to 4m deep (detached) or 3m (semi-detached/terraced) typically don't need a planning application. Petersfield has a substantial conservation area covering much of the town centre and The Spain, where full planning permission is required and materials are scrutinised closely. Petersfield is also close to the South Downs National Park boundary. East Hampshire District Council administers planning for Petersfield, and we assess your situation at every complimentary consultation.

Our fixed fees are £1,950 + VAT for Pre-Build, £2,950 + VAT for Premium, and £3,950 + VAT for Premium Plus. Build costs in the Petersfield area typically run £1,850–£2,800 per m² + VAT given the high-specification homes common in the area and the local contractor market.

Petersfield town itself is not within the South Downs National Park, but the surrounding countryside — and many rural properties — are. If your property is within the national park boundary, your planning authority is the South Downs National Park Authority rather than East Hampshire District Council, and significantly more restrictive policies apply around extension scale and materials. We check national park boundary status as part of every initial feasibility assessment.

Petersfield has an affluent housing market with many Victorian and Edwardian detached and semi-detached properties in and around the town, and larger rural properties in surrounding villages including Steep, Liss, Buriton and East Meon. Heritage-sensitive single-storey rear extensions, kitchen-diners with bifold doors and orangery-style roof lanterns are popular. Many rural Petersfield properties suit large open-plan extensions given their substantial footprints.

We cover GU31 and GU32 postcodes including Petersfield town, Steep, Liss, Liss Forest, Buriton, East Meon, Sheet and Stroud. We also work in surrounding East Hampshire including Alton, Bordon and the Whitehill & Bordon area.
