Hampshire Build Expands into Hertfordshire for 2026

Key Takeaway

We're excited to announce our expansion into Hertfordshire, bringing our extension design services to St Albans, Watford, Stevenage and towns across the county.

Exciting News: Hampshire Build Comes to Hertfordshire

We're thrilled to announce that Hampshire Build is expanding our professional extension design services into Hertfordshire for 2026. After years of successfully helping Hampshire families create their dream extensions, we're now bringing our expertise to homeowners across this beautiful county.

Why Hertfordshire?

Hertfordshire is home to some of the most stunning properties in South East England, from Victorian terraces in St Albans to characterful cottages in the Chilterns. Many Hertfordshire homeowners face the same challenges as our Hampshire clients - needing more space but wanting to stay in homes and communities they love.

The county's proximity to London means property prices are high, making extending an attractive alternative to moving. We understand the unique planning considerations in Hertfordshire, including:

• Conservation areas: St Albans alone has 28 conservation areas requiring sensitive design approaches
• Green Belt restrictions: Much of Hertfordshire falls within the Metropolitan Green Belt
• Listed buildings: Historic properties requiring specialist knowledge
• Local character: Understanding what different councils expect to see in applications

Towns We Now Serve

Our Hertfordshire expansion covers the entire county, with dedicated local pages for:

• St Albans: Roman heritage and Victorian character homes
• Watford: Diverse housing stock from period to modern
• Stevenage: Post-war new town with garden city planning
• Hemel Hempstead: New town development with extension potential
• Welwyn Garden City: Arts and Crafts influenced properties
• Hitchin: Historic market town with medieval core
• Bishop's Stortford: Growing commuter town near Stansted
• Berkhamsted: Chilterns AONB with character properties
• Harpenden: Affluent village with period properties
• Hertford: Historic county town with castle heritage

Same Fixed-Fee Packages, Same Quality

Hertfordshire clients will enjoy the same transparent, fixed-fee packages that have made us the trusted choice for Hampshire families:

• Pre-Build Package (£1,950 + VAT): Measured survey, planning drawings and application submission, Building Notice drawings and required structural calculations prepared by an independent qualified structural engineer
• Premium Package (£2,950 + VAT): The defined design package plus contractor tender support, two cost proposals, a schedule of works and a client-focused building contract issued for signature
• Premium Plus Package (the current published fee): Everything in Premium, plus an indicative staged programme, Building Notice submission (council fee excluded) and one Party Wall notice to one adjoining owner

The package fee is fixed for the stated scope. Statutory fees, third-party costs and separately agreed additional work are distinct from the package fee.

With over 300 successful extension projects across Hampshire and Surrey, we've developed an in-depth understanding of what planning officers look for. This expertise transfers directly to Hertfordshire applications, giving you confidence that your project is in experienced hands.
