TCM Building delivers extensions, loft conversions, refurbishments, and property maintenance across Borehamwood and the surrounding areas of Hertsmere. A trusted local builder with over 15 years of experience in the area.
Borehamwood is one of TCM Building's most active service areas in Hertfordshire. The town's mix of post-war housing estates, 1960s and 1970s semis, and more recent new-build developments presents a wide range of building and maintenance opportunities — from loft conversions and rear extensions on the area's characteristic flat-roofed and low-pitched properties to full refurbishments of older housing stock.
TCM has been working in Borehamwood for over a decade, building a strong reputation for quality, reliability, and transparent pricing. We have completed projects across all parts of the town — from the Cowley Hill and Shenley Road areas to Elstree and the surrounding villages.
Borehamwood falls within the Hertsmere Borough Council planning area. We have extensive experience working with Hertsmere's planning department and a strong track record of securing approvals for extensions, conversions, and other projects across the borough.

Hertsmere Borough Council handles all planning applications for Borehamwood. The council has a generally supportive attitude towards well-designed residential extensions, and many projects in the area can be carried out under Permitted Development rights. We advise on the planning position for every project during the free site survey.
Borehamwood's housing stock is predominantly post-war — 1950s, 1960s, and 1970s semi-detached and terraced houses, many with flat or low-pitched roofs. This stock is well-suited to single-storey rear extensions and garage conversions. Loft conversions are possible on many properties but require careful assessment of the existing roof structure.
Some parts of Borehamwood — particularly around the Elstree and Borehamwood Conservation Area — have restrictions on external alterations. The Green Belt boundary also affects some properties on the outskirts of the town. Our team is experienced in navigating these constraints and advising on the best approach.

"TCM built a rear extension on our 1960s semi in Borehamwood. The team was professional, clean, and efficient. The extension is beautifully finished and has completely transformed our ground floor. Excellent value."
"We had our loft converted by TCM — a dormer conversion with a bedroom and en-suite. The project was completed on time and on budget. The quality of the finish is exceptional. We would recommend TCM without hesitation."
