Increase Property Value
A well-designed loft conversion can add up to 25% to your home's value — a smarter investment than moving.
Type 01
Velux Loft Conversion
The most cost-effective option for homes with sufficient headroom. Rooflight windows flood the space with natural light and often fall within permitted development — ideal where external dormers may not be permitted.
- Cost effective solution
- Abundant natural light
- Minimal structural disruption
- Fast installation timeline
Type 02
Dormer Loft Conversion
A box-shaped extension to the existing roof creating a horizontal ceiling and vertical walls. One of the most popular ways to maximise usable floor area across Leeds terraced and semi-detached homes.
- Maximum usable floor area
- Vertical walls for furniture
- Room for ensuite bathroom
- Excellent headroom throughout
Type 03
Mansard Loft Conversion
A dual-slope roof with a flat top section — the most spacious conversion type. Usually requires planning permission but delivers the greatest increase in living space and property value.
- Largest possible loft space
- Near full-storey room height
- Ideal for master suites
- Significant value uplift
Type 04
Hip to Gable Conversion
The sloping side of a hip-end roof is built up to create a gable wall, significantly increasing internal floor area. Often combined with a rear dormer for maximum space on semi-detached properties.
- Substantial extra floor area
- Perfect for hip-end roofs
- Pairs well with dormers
- Strong kerb appeal
Type 05
L-Shaped Dormer
Two dormers connected together — popular on Victorian and Edwardian properties with a rear addition. Creates a large open-plan master suite or multiple bedrooms with ensuite.
- Expansive open-plan potential
- Multiple bedrooms possible
- Ideal for period properties
- Premium finished space

Planning Permission & Costs
Everything you need to know before starting your loft conversion, handled for you by our experienced team.
Planning Requirements
Many loft conversions fall within permitted development and do not require full planning permission — particularly Velux and smaller dormer projects. Mansard and L-shaped dormers typically require planning approval. We assess your property at the free survey and manage all applications on your behalf.
Building Regulations
Building regulations approval is always required for loft conversions — covering structural integrity, fire safety, insulation, ventilation and staircase access. Our team prepares all structural calculations and liaises directly with building control throughout the project.
Typical Timelines
Without planning permission: allow 2–4 weeks for structural calculations, detailed plans and party wall agreements before construction begins. With planning permission: expect 8–12 weeks for the application process. Most loft conversions take 6–10 weeks on site once work starts.
Expected Budgets
Velux conversions typically start from £25,000. Dormer conversions range from £35,000–£55,000 depending on size and specification. Mansard and L-shaped dormers are premium options from £50,000 upwards. We provide a detailed, no-obligation quotation after your free site survey — with no hidden extras.
