TCM Building in Radlett:
Local Knowledge, Expert Results
Radlett is one of Hertfordshire's most sought-after villages. Its combination of large plots, excellent train links to London St Pancras (under 20 minutes), and a strong community character makes it a location where homeowners consistently invest in improving their properties rather than moving. The demand for high-quality extensions and conversions in Radlett is consistently high, and the standard of finish expected by local homeowners reflects the area's character.
TCM Building & Maintenance is based in Borehamwood, less than three miles from Radlett. We have been working in the village and the surrounding Hertsmere area since 2014, completing projects ranging from single-storey rear extensions on 1930s semis to full double-storey additions on Victorian detached properties. Our proximity means we can respond quickly, manage projects efficiently, and draw on a genuine understanding of the local planning environment.
Planning applications in Radlett are handled by Hertsmere Borough Council. The council's planning team is generally supportive of well-designed residential extensions, but the Green Belt boundary runs close to the village and affects a number of properties, particularly those on the outskirts towards Aldenham and Letchmore Heath. TCM advises on the planning position for every project during the free site survey.

Why Local Knowledge
Matters for Building Work
Hertsmere Borough Council (hertsmere.gov.uk) is the local planning authority for Radlett. Many projects can proceed under permitted development rights — single-storey rear extensions up to 4 metres (or 6 metres under the neighbour consultation scheme) and loft conversions adding up to 40 cubic metres on semi-detached properties. Properties within the Radlett Conservation Area or on Green Belt land require a more detailed planning assessment.
Radlett's housing stock reflects the village's development across several eras. Victorian and Edwardian detached properties on Watling Street have generous rear gardens well-suited to extensions. The 1930s semi-detached stock is well-suited to rear extensions and loft conversions. More recent large detached properties often have scope for garden studios, annexes, and significant extensions. Plot sizes in Radlett are generally larger than in comparable Hertfordshire towns.
The Metropolitan Green Belt boundary runs close to Radlett, and a number of properties on the village's outskirts fall within or adjacent to the Green Belt. Extensions must not result in disproportionate additions to the original dwelling, and the cumulative effect of previous extensions is taken into account. The Radlett Conservation Area covers parts of the village centre and imposes restrictions on external materials and design.

What Our Radlett Clients Say
"TCM built a rear and side-return extension on our 1930s semi in Radlett. The project added a large open-plan kitchen-diner and a utility room. The team managed the Hertsmere planning process, the structural engineer's calculations, and the build itself. Everything was completed on time and exactly on budget."
"We had a dormer loft conversion done by TCM — a bedroom and en-suite bathroom. From the initial survey to the final snag list, the team was professional and communicative. They handled the Hertsmere neighbour consultation process without any issues. The new room is beautifully finished."
"TCM carried out a full refurbishment of our Victorian detached property in Radlett — new kitchen, two bathrooms, and complete redecoration throughout. The project took 14 weeks and was managed with real professionalism. We would use TCM again without hesitation."
