Service Overview

Rapid Professional
Drainage Response

A loft conversion is the most cost-effective way to add a proper room to a London home, because the space and the roof are already there. We handle the full conversion: structural steels and new floor joists, dormer or mansard construction, staircase, insulation, roof windows, plumbing for an ensuite, electrics, plastering and decoration, all coordinated through Building Control. Which type suits your home depends on the roof. A rear dormer is the workhorse on a London terrace, a hip-to-gable suits a semi or end-of-terrace, and a mansard often fits best in a conservation area. Head height is the make-or-break factor, so we measure it honestly at survey and tell you straight whether a conversion will work before you spend anything.

When You Need This Service

A growing family needing another bedroom without moving house
Unused roof space sitting empty above the top floor

Approved loft drawings that need an experienced team to build

Step-By-Step Fulfillment

01

Survey & Design

We measure head height and roof structure, advise the conversion type that fits, and confirm planning and Building Control requirements.

02

Structure

Steels, new floor joists, the dormer or roof alterations and the staircase are built, with Building Control signing off each stage.

03

Fit Out

Insulation, glazing, any ensuite, electrics, plastering and decoration complete the room, ending with your completion certificate.

Technical Clarifications

Many rear dormer conversions fall under permitted development, but limits are tighter in conservation areas and do not apply to flats and maisonettes. We confirm at survey whether you need a full application or a lawful development certificate.
As a rough guide you want at least 2.2 to 2.4 metres from the floor to the ridge before conversion. If it is short, options like lowering the ceiling below or a mansard can still work. We measure and tell you honestly before you spend anything.
Typically eight to twelve weeks on site for a standard dormer conversion, depending on type, access and whether an ensuite is included. You receive a written programme with staged milestones before work begins.
