TW9, TW10 Conservation Area Specification
Richmond upon Thames covers 70+ designated conservation areas — Richmond Hill, Richmond Green, Petersham, Ham Common, Kew Green, and the riverside frontages. The dominant noise source for most TW9/TW10 properties is Heathrow approach traffic during easterly operations (around 30% of the year), with Lmax pass-by levels of 70–78 dBA. Secondary noise sources are the A316 (50–60 dBA at distance), the District Line and Richmond station, and Thames boat traffic in summer. LBH Richmond's planning policy CP7 explicitly identifies secondary glazing as the preferred upgrade route for conservation-area and listed properties.
- Properties under Heathrow approach (north Richmond, Kew): 10.8mm acoustic + 200mm cavity, Rw 52 dB combined
- A316-adjacent (East Sheen, Mortlake): 8.8mm acoustic + 150mm cavity, Rw 48 dB combined
- Riverside and quieter conservation interiors: 6.8mm acoustic + 150mm cavity, Rw 46 dB combined
- Thermal-led briefs: Low-E secondary glass + 150mm cavity, Uw 1.6 W/m²K (74% reduction over single-glazed primary)
- Conservation Area Consent: we supply CAC submission packages including drawings, performance schedules, and Historic England compliance notes
