Services
Dormer Loft Conversion
A dormer loft conversion adds vertical walls and windows to create usable space. Ideal for increasing headroom and natural light, this cost-effective solution suits most properties. Our team ensures compliance with permitted development rules where applicable.
Hip to Gable Conversion
This conversion replaces sloped roof sections with vertical walls to maximise space. Suitable for semi-detached and detached homes, it typically requires no planning permission unless in conservation areas. Includes full structural support and finishing.
Mansard Loft Conversion
A mansard conversion provides maximum living space by altering the roof gradient. Requires planning permission and building regulations approval. Ideal for creating multi-room layouts while maintaining aesthetic harmony with existing architecture.
Velux Loft Conversion
This simple solution uses roof windows to enhance headroom and light. Typically exempt from planning permission unless in restricted areas. Cost-effective for properties with existing structural suitability and ample attic space.
L-Shaped Dormer Conversion
Combines two dormers for an L-shape, ideal for Victorian and Edwardian properties. Creates large spaces suitable for multiple rooms. Planning permission may be required depending on property type and location.
