Loft Conversion Types in Walthamstow – Dormer, Mansard, Hip-to-Gable & Velux

Dormer Loft Conversion
Dormer loft conversions are well-suited to Walthamstow’s traditional terrace housing, increasing roof space and bringing in natural light. Planning approval may be required, depending on roof alterations and dormer dimensions.
Our dormer loft conversion services include:
- Drafting of planning-compliant L-shaped and rear dormer layouts
- Construction of framed box and pitched dormer extensions
- Custom-built staircase installation to access new floors
- Fitting of additional rooms like bedrooms or workspaces
- Handling party wall notices and neighbour agreements
- Full submission to local building control

Attic Loft Conversion
Ideal for houses with underused roof space, attic loft conversions are common across Walthamstow’s post-war semis and bungalows. They offer a cost-effective expansion within the existing roof envelope.
Our attic loft conversion services include:
- Adaptation of ceiling height and pitch for usability
- Installation of attic insulation, boarding, and roof lining
- Custom attic staircase installation
- Electrical, lighting, and ventilation upgrades
- Structural reinforcement as required

- Ventilation improvements for existing attic spaces
- Installation of custom-fit blackout blinds and privacy screens
