What Teddington homeowners ask us.
Do I need planning permission for a loft in Teddington?
Teddington Village and Bushy Park conservation areas cover specific pockets. Outside conservation areas, most rear-dormer conversions in Teddington qualify for permitted development (PD) within the 40m³ (terrace) or 50m³ (semi/detached) volume limits. Mansards always need full planning. We check your specific address before quoting and submit the application on your behalf.
Are 1930s Teddington semis good loft candidates?
Yes — the hipped roofs respond well to hip-to-gable conversions, which usually qualify for PD. Combined with a rear dormer, this typically adds two bedrooms and a bathroom for £120–£155k all-in. Richmond Council's planning team handles these efficiently.
How long does a Teddington loft conversion take?
Typical timeline: 6–10 weeks for design and planning (longer in conservation areas like much of Teddington), then 8–14 weeks on site for a standard dormer, 12–18 weeks for an L-shape or hip-to-gable, and 14–20 weeks for a mansard. LB Richmond upon Thames processes PD-route Lawful Development Certificates in approximately 8 weeks.
What does a loft conversion add to Teddington property values?
In TW11, a well-executed loft conversion typically adds 15–25% to property value — often more in prime postcodes. The ROI is strongest when you add a double bedroom plus en-suite, which is the standard L-shape dormer configuration. Property uplift on a £43k–£209k build commonly exceeds the build cost by 30–60%.
