Loft conversions, built properly.
Dormer and roof light conversions that turn unused roof space into proper rooms, managed from drawings to completion certificate.
Making real use of your roof space
A loft conversion is a structural job, not just a new floor and a window. We handle every part of it so you have one company answering for the work.
We start with a site visit to look at your roof, head height and where a stair could go. CWJ Architectural Design Services prepares the drawings and the building warrant application, and our quantity surveyors cost the work to the approved warrant. Our team then builds the new floor, the structure, any dormer, the stair and the insulation, followed by the electrics, plumbing, plastering and joinery. Most clients stay at home during the work, so we keep the working area separate and leave the house clean and usable each day.

Types of loft conversion
Dormer conversions
A dormer adds head height and floor space by building out from the roof slope. It suits bedrooms and en suites.
Roof light conversions
Windows are fitted into the existing roof slope, keeping the roof shape as it is. This works where there is already good head height.
Loft bedrooms with en suites
Extra bedroom space with a shower room or bathroom built in, planned around the drainage and the roof shape.
Loft offices and studies
A quiet room away from the rest of the house, with proper insulation, heating and lighting.
Loft playrooms
A bright, safe space for children, kept separate from the main living areas.
Lofts with a new staircase
A proper staircase planned into the floor below, so the loft works as a real room every day.
Why design and build works better
Most homeowners hire an architect, then try to find a builder to match the drawings. With design and build, one company does both, and that changes how the whole project runs.
One contract, one company
Design, costing and build sit with one firm. If something needs sorting, there is one company answering for it, not an architect and a builder pointing at each other.
Cost in mind from the first sketch
Our designers work alongside our quantity surveyors and site team, so the build cost is considered while the drawings are being made, not after.
Drawings that suit the build
The people drawing your project work with the people building it, so details are worked out with the build in mind before anything reaches site.
No gaps between stages
There is no handover from one firm to another between design, warrant and build. The same team carries the project from the first visit to the completion certificate.
We deal with the council
We handle planning and the building warrant, and deal with the council right through to the completion certificate.

Although the disruption surrounding building works is never pleasant, it has been a pleasure working with Oscar and Kris at Cutwood. ... the end result after 6 months work, certainly so far as the dormer is concerned, is better then we were hoping for.Martin H.Loft and garage conversion · Google review

Loft Conversions FAQs
Is my loft suitable for a conversion?
It depends on the head height, the roof structure and where a stair can go. We check all of this on a site visit before anything else.
Do I need a building warrant?
A loft conversion is structural work and normally needs a building warrant. Whether you also need planning permission depends on the design, and we check both at the start.
Can we stay at home during the work?
Most of our clients do. We keep the working area separate and leave the house clean and usable every day.
Dormer or roof lights, which is better?
It depends on your roof and what you want to use the room for. A dormer gives more head height and floor space, roof lights keep the roof shape. We talk through both at the site visit.
What is included in your price?
The main price covers building to the approved building warrant. Finishing items such as flooring and decoration are listed separately with their own prices, and anything not included is written down.
How long does a loft conversion take?
Every project is different, but loft conversions are usually 5 to 7 weeks on site.
Who handles the drawings?
Our sister company, CWJ Architectural Design Services, prepares the drawings and handles the building warrant, and planning if it is needed.
Will I need a new staircase?
Yes, a converted loft needs a proper staircase. Where it goes is one of the first things we look at on the site visit, as it affects the rooms below.
Can you add an en suite in the loft?
Often, yes. It depends on where the drainage and water supply can run, which we check at the start.
Who prices the loft conversion?
Our own quantity surveyors price the work from the approved building warrant drawings. Finishing items are listed separately as optional extras.
Do you deal with the council?
Yes. We deal with the council from the warrant application through to the completion certificate.
