Key Takeaway
Following strong demand from homeowners outside Hampshire, we're pleased to confirm that Hampshire Build now formally covers West Sussex and Berkshire — bringing our fixed-fee extension design packages to even more families across the South East.
Expanding Across the South East
Hampshire Build was founded in Winchester to serve homeowners across Hampshire, and over the past three years we've grown steadily — first into Surrey and Hertfordshire, and now formally into West Sussex and Berkshire. This expansion reflects consistent demand from homeowners who've heard about our fixed-fee model and want the same transparent, expert service for their own extension projects.

Check your extension projectWhy We're Expanding
The South East of England has some of the highest property values in the UK outside London, which makes extending your existing home — rather than moving — an especially attractive proposition. In West Sussex and Berkshire, we're seeing strong demand for rear kitchen extensions, two-storey additions to semi-detached homes, and loft conversions. These are exactly the project types our packages are designed to deliver efficiently.
We've also been approached by homeowners in areas such as Chichester, Horsham, Reading, Newbury, and Wokingham who found our reviews and wanted to work with a fixed-fee designer rather than a traditional architectural designer charging hourly rates.
What's Covered in Our New Service Areas
Our full range of packages is now available across West Sussex and Berkshire:
- Pre-Build Package (£1,950 + VAT): Measured survey, planning drawings and application submission, building regulation drawings prepared for Building Notice submission, and required structural calculations prepared by an independent qualified structural engineer.
- Premium Package (£2,950 + VAT): The same defined design scope, plus a schedule of works, contractor tender support to two vetted contractors, two cost proposals, and a client-focused building contract issued for signature.
- Premium Plus Package (£3,950 + VAT): Everything in Premium, plus an indicative staged programme, Building Notice submission and one Party Wall notice to one adjoining owner.
Local Knowledge Matters
One of the first things we do when entering a new area is review each local planning authority's adopted policies and design guides. West Sussex spans several local authorities — including Chichester District Council, Horsham District Council, and Mid Sussex District Council — each with their own approach to residential extensions. Berkshire similarly covers multiple authorities, including West Berkshire Council and Windsor and Maidenhead.
