What we offer
Loft conversions done properly
Three conversion types. One specialist team. We'll tell you which is right for your home — and why.
The most popular choice for South Yorkshire homes
Dormer Conversion
A dormer conversion extends vertically from the existing roof slope, adding a box-shaped structure with a flat or pitched roof. This dramatically increases headroom and usable floor space, making it the most versatile and popular conversion type.
Typical cost
£25,000–£40,000
Duration
6-10 weeks
Planning
Usually permitted development
Best for
Homes with a standard pitched roof looking to add a master bedroom with en-suite, a large double bedroom, or a home office with full standing height.
What's included
- Full structural design and calculations
- Planning application or permitted development sign-off
- Building regulations approval and inspections
- Dormer structure, roofing, and weatherproofing
- Insulation, plastering, and first-fix electrics
- Staircase design and installation
- Windows, Velux lights, and joinery
- 10-year structural warranty
Common questions
Maximum space for semi-detached and detached homes
Hip-to-Gable Conversion
A hip-to-gable conversion replaces the sloping 'hip' end of your roof with a vertical gable wall. This unlocks a significant amount of floor space that would otherwise be unusable due to the sloping roof structure.
Typical cost
£40,000–£65,000
Duration
10–14 weeks
Planning
Often requires planning permission
Best for
Semi-detached and detached homes with a hipped roof — particularly 1930s and 1950s properties common across South Yorkshire — where maximum loft space is the priority.
What's included
- Full structural design and calculations
- Planning application management
- Building regulations approval and inspections
- Hip-to-gable structural conversion
- New gable wall, roofing, and weatherproofing
- Insulation, plastering, and first-fix electrics
- Staircase design and installation
- 10-year structural warranty
Common questions
The most cost-effective way to use your loft space
Velux & Roof Light Conversion
A Velux conversion works within the existing roof structure — no changes to the roofline. Velux or equivalent roof lights are fitted into the existing slope to bring in natural light and ventilation. It's the quickest and most affordable conversion type.
Typical cost
£20,000–£35,000
Duration
5-7weeks
Planning
Permitted development in most cases
Best for
Homes where the existing loft already has reasonable headroom (at least 2.2m at the ridge), or where budget is the primary consideration. Also ideal where planning restrictions prevent roof alterations.
What's included
- Structural assessment and floor strengthening
- Building regulations approval and inspections
- Velux or equivalent roof light installation
- Insulation to current building regulations
- Plastering, boarding, and first-fix electrics
- Staircase design and installation
- 10-year structural warranty
