BUILDING IN TOOTING BEC
Tooting Bec is a vibrant mix of Edwardian terraces and 1930s semis. It offers good value for families who want to upsize without leaving London.
Dormer and hip-to-gable conversions add bedrooms and home offices. L-shaped dormers can provide two new rooms in larger houses.
Tooting Bec projects include a wrap-around extension with a garden-facing kitchen and a mansard conversion used as a home office/studio.
Local advantage
Why Tooting Bec homeowners choose DPS for loft conversions
01 · PLANNING HANDLED
We handle the permission side in-house.
Planning drawings, building-regulations and party-wall paperwork are prepared and submitted by our own team —
including for conservation-area or listed properties where extra consent is needed. One point of contact owns
both the approvals and the build, so nothing falls between an architect and a separate contractor.
02 · ONE TEAM
Architects, builders, project managers — all in-house.
No subcontractor juggling. From the first sketch through structural engineering to final snagging, your project moves
through people who all sit in the same office and answer to the same project manager.
03 · TRANSPARENT PRICING
£60k–£140k typical — itemised and fixed.
You pay in stages, only after each stage is signed off. Variations only happen when scope genuinely changes — and
they go through written authorisation, never a verbal "while we are at it".

Will my loft conversion need planning permission?
Many lofts fall under permitted development if you stay within volume limits. Conservation areas always need full planning. We handle either route.
How tall must my loft be to convert?
You need at least 2.2m of head height in the existing loft. We measure on the first visit and confirm what conversion fits.
Will the build be disruptive?
Most of the work happens upstairs, with rooflight access for materials. You stay in your home throughout.
