Many Alton extensions can be built under Permitted Development Rights without a formal planning application. Single-storey rear extensions up to 4m deep (detached) or 3m (semi-detached/terraced) are often PD compliant. Alton town centre and parts of surrounding villages are within conservation areas administered by East Hampshire District Council, where full planning permission is required and materials are scrutinised closely. We assess your PD status at every complimentary consultation.
Our fixed fees are: Pre-Build Package from £1,950 + VAT (planning drawings), and Premium Plus from £4,950 + VAT. Build costs in the Alton area typically run £1,800–£2,700 per m² depending on specification. Alton's proximity to the South Downs National Park can sometimes affect choice of materials and build methods, which influences cost. Use our Extension Cost Calculator for a project-specific estimate.
Alton itself is not within the South Downs National Park, but parts of the surrounding countryside (to the south and east) are within or adjacent to the park boundary. If your property is within the park, your planning authority is the South Downs National Park Authority rather than East Hampshire District Council, and more restrictive policies apply. We check boundary status as part of every initial feasibility assessment.
East Hampshire District Council handles planning applications for Alton and the surrounding villages (Four Marks, Holybourne, Bentworth, Medstead). EHDC is generally efficient and targets an 8-week determination period for householder applications. We have experience submitting applications to EHDC and understand their design expectations.
We cover GU34 postcodes including Alton town, Four Marks, Holybourne, Bentworth, Medstead, Beech, Froyle, Binsted and surrounding villages. We also work in neighbouring Farnham, Petersfield and Fleet — all within East Hampshire or Hart District.
Book a complimentary consultation. We'll visit your Alton property and advise on planning and costs — at no charge.
