Loft Conversions in London & Surrey
Unlock the full potential of your home with a professionally designed loft conversion by DPS Ltd. We create bright, comfortable spaces that add real, usable square footage and long-term value — from master bedrooms with en-suite to home offices and family rooms. Serving South West London & Surrey, we handle everything from design and permissions to the final finish.
Transform Your Attic into a Smart, Stylish Living Space
A loft conversion is one of the most cost-effective ways to expand without moving. We optimise headroom, natural light and layout so the new space feels like it has always belonged to your home. Our team manages the technical side — structural designs, building regulations and approvals — while you focus on how you’ll use the space.

Types of Loft Conversions We Deliver
- Dormer Loft Conversion – Adds vertical walls and a flat roof section for generous headroom; ideal for bedroom + bathroom layouts.
- Velux / Rooflight Conversion – Minimal structural change, maximum daylight and ventilation; great where planning sensitivity applies.
- Hip-to-Gable Conversion – Extends a hipped roof to a full gable, unlocking valuable floor area in semi-detached and end-terrace homes.
- Mansard Conversion – Steeper rear roof angle to maximise internal volume; a premium option for period properties and townhouses.
