A look inside a loft we’ve transformed — press play for a full walkthrough of the finished space.

A full walkthrough of a completed Pimlico loft conversion: two new rooms, a new bathroom and a new staircase, all created from previously unused roof space.

Two unused rooms in the roof turned into two bedrooms, a new bathroom and a new staircase, built from structural carpentry through to a fully finished, decorated space. The whole conversion was handled by one team, from first fix right through to the final coat of paint.

Areas We Cover

We convert lofts across these areas.

From Rafters to Finished Rooms

Everything that goes into a loft conversion, from structural carpentry through to a fully finished, decorated space — handled by one team.

Structural Timber & Roof Works
Loft structural timber and roof works

We install new structural timber and floor joists at roof level, working under a temporary scaffold roof and tying into existing chimney stacks and party walls to form a sound, load-ready floor.

  • New structural timber and floor joists at roof level
  • Temporary scaffold roof keeping the loft weathertight
  • Tied into the existing chimney stack and party walls
  • Engineered and signed off by a structural engineer
Dormer & Stud Framing

We build new timber dormers and stud framing to form the loft rooms, running first-fix services through the frame while retaining the original brickwork.

  • New timber dormers extending the usable floor space
  • Stud framing forming the new loft rooms
  • First-fix electrics and plumbing run through the frame
  • Original brickwork retained
Staircases
New loft staircase

We design and build new staircases to connect the loft to the floor below, made to fit the space and built to current building regulations.

  • Bespoke staircases to suit the existing layout
  • Building-regulation rise, going and headroom
  • Balustrades, handrails and finishes
  • Cleanly integrated into the floor below
Bathrooms & En-Suites
New loft bathroom

We build bathrooms and en-suites into the loft, handling all plumbing, tiling and sanitaryware from waste runs through to the finished fit-out.

  • New bathrooms and en-suites within the loft
  • All hot, cold and waste plumbing
  • Tiling, sanitaryware and screens
  • Extraction and ventilation
Room Creation
Finished loft bedroom

We turn unused roof space into proper, usable rooms — insulated, boarded and finished as bedrooms, studies or living space.

  • Extra rooms from unused roof space
  • Insulation to thermal and acoustic standards
  • Dormer and rooflight windows for light and air
  • Finished as bedrooms, studies or living space
Drylining, Plastering & Finishes
Finished and decorated loft room

We board, plaster and decorate throughout, taking the structure to a smooth, paint-ready and fully finished space.

  • Plasterboarding and skim finishes throughout
  • Second-fix carpentry, doors and skirting
  • Flooring, decoration and making good
  • A clean, snag-free handover

What a Loft Conversion Solves

The reasons homeowners call us in — and how converting the loft puts them right.

01
Running Out of Space

Growing families and working from home leave you short of rooms. A loft turns dead roof space into two usable rooms without losing any of your garden.

02
Moving Isn’t Worth It

The cost and upheaval of moving rarely adds up. A loft conversion adds space and value while you stay in the home you already love.

03
Wasted Roof Space

Most lofts are lost to storage. We open them up, insulate and frame them into proper, comfortable living space with a new staircase and bathroom.

04
Coordinating the Build

Carpenters, roofers, plumbers, electricians and plasterers — we manage every trade as one contractor, with a single point of contact throughout.
