Trusted builders in St Albans since 2014. TCM Building & Maintenance delivers house extensions, loft conversions, and full refurbishments across St Albans and the surrounding Hertfordshire villages.
St Albans is one of Hertfordshire's most historically significant cities, with a character shaped by its Roman origins, its medieval cathedral, and its development as a prosperous market town. The city's housing stock reflects this layered history — Victorian and Edwardian terraces and semis in Fleetville and Bernards Heath, large Edwardian and inter-war detached properties in the Marshalswick and Jersey Farm areas, and a range of post-war housing across the district. This diversity of property types creates strong and consistent demand for extensions, loft conversions, and refurbishments.
TCM Building & Maintenance has been working in St Albans since 2014. Our base in Borehamwood is approximately eight miles from St Albans city centre, and we have completed projects across all parts of the city and the surrounding district — from rear extensions on Victorian terraces in Fleetville to loft conversions on large Edwardian properties in the Clarence Park area, and commercial fit-outs in the city centre.
Planning applications in St Albans are handled by St Albans City and District Council. The council is known for a careful approach to development, particularly in the city's conservation areas and in the Green Belt, which covers a significant proportion of the district. TCM advises on the planning position for every project during the free site survey, including whether permitted development rights apply or whether a full application is required.

St Albans City and District Council (stalbans.gov.uk) is the local planning authority for the city and district. The council's Local Plan is protective of the city's historic character and the surrounding Green Belt. The city centre and a number of residential areas are designated as conservation areas, where permitted development rights are restricted. The Green Belt covers a large proportion of the district, and extensions to Green Belt properties are subject to strict planning tests. TCM will confirm the planning position and any relevant constraints during the free site survey.
St Albans has a diverse and high-quality housing stock. Victorian and Edwardian terraces in Fleetville, Bernards Heath, and Cottonmill are well-suited to rear extensions and loft conversions. The large Edwardian and inter-war detached properties in Clarence Park, Marshalswick, and the roads around the city centre offer scope for significant extensions and garden studios. Post-war housing in Jersey Farm, Chiswell Green, and Sandridge is well-suited to single-storey rear extensions. The district also has a number of villages — Redbourn, Sandridge, St Stephen, and London Colney — with a mix of period and modern properties.
St Albans City and District Council takes a careful approach to development, particularly in the city's conservation areas and in the Green Belt. The city centre conservation area and the Clarence Park conservation area both restrict permitted development rights and require planning permission for external alterations. The Green Belt covers a large proportion of the district, and extensions to Green Belt properties must not result in disproportionate additions to the original dwelling. The council's design guidance requires extensions and alterations to use materials and detailing that are sympathetic to the existing property and the local streetscape. TCM has extensive experience navigating these constraints.

"TCM built a rear extension on our Victorian terrace in Fleetville — a large open-plan kitchen and dining room with bifold doors onto the garden. The team managed the St Albans planning application, the structural calculations, and the build. The project was completed on time and the quality of the finish is outstanding. We would recommend TCM without hesitation."
"We had a dormer loft conversion completed by TCM on our Edwardian semi in Bernards Heath. The new master bedroom and en-suite are beautifully finished. The team was professional throughout, communicated well, and the programme was accurate. The St Albans planning process was managed entirely by TCM."
"TCM carried out a full kitchen and bathroom renovation in our 1930s semi in Marshalswick. The team was respectful of our home, the work was completed to a very high standard, and the final cost matched the quote. The project manager was excellent — always available and kept us fully informed. We are delighted with the result."
