Practical Extensions, based on your needs, home potential & St Albans requirements

St Albans homeowners often face tight Victorian terraces or 1930s semis that don’t suit growing families or remote work needs. With excellent schools and superb commuter links to London, many choose to extend rather than relocate. HomeExtensionsRUs specialises in practical extensions like rear additions or loft conversions, tailored to local constraints such as Conservation Areas and Green Belt rules.

Planning Permission for Home Extensions in St Albans

St Albans City & District Council oversees one of Hertfordshire’s more stringent planning regimes, with 68% of the district in Conservation Areas or Green Belt.

Article 4 directions often remove Permitted Development rights in central wards, meaning even small rear extensions may need full approval. We recommend pre-application advice to avoid delays, and our team secures 100% success by aligning designs with the Local Plan.

Typical determination takes 8-11 weeks, but our proactive submissions average 7-9 weeks.
