A loft conversion is one of the most cost-effective ways to add genuine living space and value to a property, without the disruption or expense of moving home. Whether you need an extra bedroom, a home office, a playroom, or a private retreat, converting your loft makes use of space that would otherwise sit empty above your home.
Core Rock Ltd designs and builds loft conversions across all 10 boroughs of Greater Manchester, managing every stage of the project from initial structural assessment and planning through to electrics, plumbing, insulation, and final decoration. We do not subcontract. The same directly employed team that assesses your loft is the team that completes the build.
Greater Manchester’s housing stock, from Victorian terraces to 1930s semis and post-war detached homes, offers strong loft conversion potential in most cases. Our team understands the structural considerations specific to these property types, including roof pitch, head height, and party wall requirements where they apply.
The simplest and most cost-effective option, using roof windows fitted into the existing roofline without altering its shape. Ideal where head height already allows for comfortable living space.
The most popular type of loft conversion in the UK, adding a box-shaped extension to the rear roof slope to significantly increase head height and usable floor space.
Suited to semi-detached and detached properties with a hipped roof, this conversion extends the sloped side of the roof outwards to create a vertical gable wall, maximising internal space.
A more substantial conversion that alters the roof structure to create a near-vertical rear wall and a flat roof, typically used where maximum space is required.
Combining two dormers to form an L-shape, this option is common on Victorian and Edwardian terraced properties and creates space for two additional rooms or a larger single room.

Costs depend on the type of conversion and the work involved. A basic Velux conversion typically starts from £20,000 to £30,000, while a dormer conversion ranges from £35,000 to £55,000, and a hip-to-gable or mansard conversion can cost £45,000 and upwards. We provide a detailed, itemised quote following a free structural survey.
Most loft conversions fall under Permitted Development Rights and don’t require full planning permission, provided they meet volume and design limits. Properties in conservation areas or those that have already extended the roof may need full planning approval. We advise on this as part of every free site visit.
Most loft conversions take between six and ten weeks from start to finish, depending on the type of conversion and any structural complexity involved. We provide a clear timeframe as part of your written quote.
In almost all cases, no. Loft conversions are typically carried out with access from outside the property using scaffolding, meaning you can usually continue living in your home throughout the build.
Yes. Loft conversions always require building regulations approval, regardless of whether planning permission is needed. We manage this process as part of our service and ensure the completed work is signed off correctly.
A Velux conversion uses roof windows within the existing roofline and is the simplest, most affordable option. A dormer conversion adds a box-shaped extension to the roof, increasing head height and floor space, making it suitable for properties where the existing roof pitch is too low for comfortable standing room.
