A room in roof conversion (also known as a loft conversion) transforms your unused attic space into a beautiful, functional room — perfect for extra bedrooms, home offices, gyms, or playrooms for Manchester homeowners.
Convert the space you already have — no need to lose garden space or deal with complex foundation work. A room in roof conversion uses existing roof volume, making it more cost-effective than a ground floor extension.
A professionally converted room in roof can add substantial value to your home — often more than the cost of the conversion itself. In Manchester’s competitive property market, a converted loft is a major selling point.
Moving house in Manchester can easily cost £10,000–£30,000 in fees and taxes, depending on your property’s price. A room in roof conversion often costs less — and you keep your neighbourhood, school catchment, and home.
Modern conversions include high-quality insulation (PIR board between and under rafters), reducing heat loss and lowering energy bills — a properly insulated conversion typically saves around £200–£400 per year on heating costs, depending on the property.
Properties suitable for room in roof conversion in Manchester:
Roof windows installed within the existing roof slope. Minimal structural work and the most cost-effective option — ideal for lofts with adequate headroom (2.2m+) and budget-conscious projects.
A box structure projecting from the roof slope, adding headroom and floor space. The most popular option for Manchester homes.
Combines rear and side dormers to create maximum floor space. Popular for Victorian terraced houses with rear extensions.

We manage all Building Regulations applications and inspections on your behalf.
Most conversions are permitted development, subject to:
You may need planning permission for:
Party Wall Agreement: for terraced and semi-detached homes, work on shared walls, excavation near foundations, or structural alterations may need an agreement with neighbours — we advise on requirements and help you serve notices. Listed buildings (Grade I, II* or II) need Listed Building Consent for most conversions — we specialise in traditional buildings and can guide you through the process.
No hidden costs or surprises — a detailed, fixed-price quotation before work starts, confirmed after your free site survey.
We handle everything from design to completion — architecture, structural engineering, planning permission, building control, and all trades. One point of contact.
All work complies with Building Regulations, with full certification provided on completion.
Retrofit standards applied to the energy-efficiency elements of your conversion — and we can help you access ECO4 funding for insulation where eligible (the scheme runs until 31 December 2026).
We know Manchester properties — Victorian terraces (Levenshulme, Burnage), 1930s semis (Stockport, Oldham, Droylsden), bungalows (Heald Green, Cheadle) — their building styles, common structural issues, and supply chains.
No-obligation advice and quote. We visit your property, assess headroom and roof structure, and provide a fixed-price quotation.
Work comes with guarantees and warranties, delivered by structural engineers, certified electricians, and Gas Safe registered plumbers.
High-quality insulation, appropriate ventilation (MVHR or extract), and energy-efficient windows specified as standard.
Typically 2.2m at the highest point for a roof light conversion. For dormer conversions, the roof profile can be altered to create more headroom. We assess your property during the free consultation.
Roof light conversions typically take 4–6 weeks, dormer conversions 6–8 weeks, and L-shaped conversions 8–12 weeks, depending on complexity.
Most conversions do not require planning permission if they fall within permitted development limits. Listed buildings and conservation areas may require permission — we advise on your specific property.
Yes. All our work complies with Building Regulations, and we arrange the necessary inspections and certification.
Yes — bathrooms, en-suites, shower rooms, or wet rooms. Adding a bathroom typically adds around £5,000–£15,000 to the project cost.
A quality conversion typically adds meaningful value — how much depends on your property type, location, and the standard of finish. We can advise based on local market evidence during your consultation.
Not if installed correctly. We include vapour control layers, insulation (100–150mm PIR), and ventilation (MVHR or extract fans) to prevent condensation.
Yes, but you may need planning permission. We specialise in traditional buildings and heritage conservation, and advise on appropriate materials (e.g. slate, tile hanging) to match the conservation area.
For most terraced and semi-detached homes, yes — where work affects shared walls or structures. We advise on party wall requirements and help you serve notices to neighbours.
