TCM Building in Hertfordshire:
Local Knowledge, Expert Results
This page is your county-level directory for TCM Building & Maintenance across Hertfordshire. Our base is in Borehamwood (WD6), and we cover every major town and district in the county — from Watford and St Albans in the south-west to Welwyn Garden City, Hatfield, and Hertford in the north-east. Use the area links below to find the page for your specific town.
TCM has active planning relationships with all the major Hertfordshire local planning authorities: Hertsmere Borough Council, St Albans City & District, Watford Borough Council, Welwyn Hatfield Borough Council, Three Rivers District Council, and Dacorum Borough Council. This multi-authority experience means we can advise accurately on permitted development limits, Conservation Area restrictions, Green Belt constraints, and Article 4 Directions for any property in the county.
Hertfordshire's housing stock is exceptionally varied — from Georgian and Victorian period properties in St Albans and Hertford to post-war semis in Stevenage and Hemel Hempstead, 1930s Metroland detached houses in Radlett and Potters Bar, and modern executive developments across the county. This variety requires a contractor with genuine breadth of experience. TCM has delivered extensions, loft conversions, basement conversions, and commercial fit-outs across all property types and all Hertfordshire planning authority areas.

Why Local Knowledge
Matters for Building Work
Hertfordshire has six principal planning authorities, each with distinct policies, character area guidance, and Conservation Area designations. Hertsmere covers Borehamwood, Radlett, Potters Bar, and Bushey. St Albans covers the city and surrounding villages. Watford Borough covers the town itself. Welwyn Hatfield covers Welwyn Garden City and Hatfield. Three Rivers covers Rickmansworth and Chorleywood. TCM has an active planning track record with all six authorities and advises on the planning position for every project during the free site survey.
Hertfordshire's housing stock ranges from historic period properties in market towns to post-war semis and modern new-build developments. Period properties — particularly in Conservation Areas in St Albans, Hertford, and Harpenden — require sympathetic materials and design approaches. Our team has extensive experience working with all property types across the county.
A significant proportion of Hertfordshire falls within the Metropolitan Green Belt, which places strict restrictions on new development and extensions. Conservation Areas in the county's historic market towns also restrict external alterations. TCM is experienced in navigating both sets of constraints and advising on the best approach for each property.
