Why Balham homeowners choose DPS for loft conversions.

01 · LOCAL KNOWLEDGE

We know the Wandsworth planning quirks.

Conservation areas, Article 4 directions, party-wall hotspots — every Wandsworth street has its own permission map. We have submitted dozens of approved schemes across Balham and the surrounding postcodes.

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 I need planning permission in Balham?

It depends on the property. Many loft conversions fall under permitted development, especially in Wandsworth. Where planning is needed (conservation areas, listed properties, larger schemes), we handle the application end-to-end.

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.
