Types of Loft Conversions We Specialize In

Dormer Loft Conversion
Dormer loft conversions extend your roof outward, adding valuable headroom and natural light. Ideal for Victorian, Edwardian, terraced, and semi-detached homes, they create practical living spaces such as bedrooms or en-suites, often requiring planning permission and building regulation compliance.

- Assistance with planning permission applications and building control approvals

Attic Loft Conversion
Attic loft conversions transform unused roof voids into functional living areas by adapting sloping ceilings, improving ventilation, and upgrading insulation. Ideal for homes with sufficient internal loft height, they enhance usability without altering the existing roofline and may require planning permission or structural reinforcement in some cases.

Velux Loft Conversion
Velux loft conversions use rooflight windows to bring natural daylight into unused attic spaces without altering the roof structure. Ideal for bungalows, detached homes, and properties in conservation areas, they offer a cost-effective and energy-efficient way to improve roof ventilation and create bright, livable loft areas.
We Offer Complete Velux Loft Conversion Services including:

Mansard Loft Conversion
Mansard loft conversions involve constructing a full-width roof extension with steeply sloping walls and a flat roof, maximising internal headroom and floor space. Commonly used in urban terraces and period properties, they require structural steelwork and full planning permission to meet building regulations.
We Offer Complete mansard Loft Conversion Services including:
- Complete mansard roof extension with sloping wall and flat roof design
- Development of detailed mansard roof design plans including pitch and dormer placement
- Installation of mansard roof dormers, insulation, and flat roof sections

Hip-to-Gable Loft Conversion
Hip-to-gable loft conversions extend the sloping side (hip) of a roof into a vertical gable wall, altering the roof profile to increase internal loft headroom. Commonly used for semi-detached and end-terrace homes, these conversions require structural reinforcement and planning permission to comply with current building regulations.

- Full hip-to-gable roof extension with structural gable wall construction
- Roof profile alteration to maximise usable loft space
- Design and adjustment of the loft floor plan to suit the new layout
