What 80+ Borehamwood Projects Tell Us
Based on over 80 projects completed in Borehamwood and the surrounding WD6 area since 2014, here is what we have learned about the local housing stock, planning environment, and what homeowners in this area typically build.
| Project Type | Typical in WD6 | TCM Median Cost | Key Consideration |
|---|---|---|---|
| Single-Storey Rear Extension | Very common — 1960s–70s semis | £46,500 | Low-pitched roofs suit flat or lean-to roof extension |
| Loft Conversion (Dormer) | Common — requires roof assessment | £51,200 | Many WD6 roofs need dormer to achieve headroom |
| Garage Conversion | Popular — integral garages widespread | £22,800 | Often permitted development; no planning needed |
| Side Return Extension | Less common — narrower plots | £53,400 | Check party wall position on terraced properties |
| Full Refurbishment | Older housing stock benefits | £68,000 | Often combined with extension for maximum value |
The Borehamwood Housing Stock: What It Means for Your Project
The majority of Borehamwood's residential stock was built between 1950 and 1975 — primarily semi-detached and terraced houses with integral or attached garages, low-pitched roofs, and standard brick cavity wall construction. This stock is well-suited to rear extensions and garage conversions, both of which frequently fall within Permitted Development limits and require no formal planning application.
Loft conversions on this era of property require careful assessment. The low roof pitches common in WD6 — typically 25–30 degrees — often provide insufficient headroom for a Velux-only conversion. In around 60% of our Borehamwood loft projects, we have recommended a dormer extension to achieve a usable room height of 2.2m or above. We assess this during the free site survey at no charge.
Properties near the Elstree and Borehamwood Conservation Area, or those on the Green Belt boundary to the north and west of the town, are subject to additional restrictions. Our team is experienced in advising on these constraints and has a 100% approval rate on all Hertsmere planning applications to date.
