Home Extensions Hemel Hempstead - Design, Planning Approval & Build
Your trusted partner for home extensions across Hemel Hempstead, Berkhamsted, Chesham, Amersham and Tring (HP1–HP6 & HP23). We deliver seamless projects with a 100% planning success rate with Dacorum Borough Council and Chiltern & South Bucks councils.
Home Extensions for families who want their home to grow with their family
Homeowners in Hemel Hempstead, Berkhamsted, Chesham, Amersham and Tring love the blend of town convenience and Chilterns countryside – but many 1960s–1980s properties are now too small for growing or multi-generational families. With excellent schools and fast rail links to London, many choose to extend rather than move.
HomeExtensionsRUs specialises in rear extensions, side returns, loft conversions and wrap-arounds perfectly suited to the HP1–HP6 and HP23 postcodes.

Serving Hemel Hempstead
Homeowners in Hemel Hempstead, Berkhamsted, Chesham, Amersham and Tring love the blend of town convenience and Chilterns countryside – but many 1960s-1980s properties are now too small for growing or multi-generational families. With excellent schools and fast rail links to London, many choose to extend rather than move.
Our extension design approach addresses the unique layouts of HP-area homes—maximising natural light in deeper 1970s plots, working with the brick and render typical of the period, and creating open-plan spaces that transform compartmented layouts. We specialise in rear extensions, side returns, loft conversions and wrap-arounds perfectly suited to the HP1-HP6 and HP23 postcodes.
Planning Permission for Home Extensions in Hemel Hempstead & Surrounding Towns
Most properties in the HP1-HP3 postcodes fall under Dacorum Borough Council, while HP4-HP6 and HP23 are covered by Buckinghamshire Council (Chiltern & South Bucks area). Both authorities are generally supportive of well-designed householder extensions, with far fewer Article 4 restrictions than many Hertfordshire districts.
Permitted Development rights are usually intact outside small conservation pockets, meaning many single-storey rear extensions up to 6 m (detached) or 8 m (with Prior Approval) can proceed without full planning. We still recommend pre-application advice for larger or two-storey projects – our track record delivers 100% approval and typically 6-8 week decisions.
