Types of Loft Conversions We Offer
Basildon Loft Conversions
Dormer Loft Conversions
The most popular choice for Basildon homes. Dormers create a box-shaped extension projecting from the roof, giving you:
Increased headroom
More usable floor space
Options for large windows or Juliet balconies
Ideal for bedrooms, offices or additional bathrooms
Velux (Rooflight) Loft Conversions
A cost-effective option that requires minimal structural changes. Benefits include:
Fast installation
Excellent natural light
Lower overall costs
Often no planning permission required
Perfect if your loft already has good head height.
Hip-to-Gable Loft Conversions
Ideal for semi-detached or end-of-terrace homes in Basildon. Extending the sloping hip roof into a vertical gable wall creates:
Substantial extra interior space
Improved layout options
A fuller, more spacious conversion
Often combined with a rear dormer for maximum impact.
L-Shaped Loft Conversions
Popular for properties with rear extensions. Offers:
Large floor areas
Great for master suites or multi-room layouts
Flexible design options
