Rear Dormer Loft Conversions
A rear dormer loft conversion is one of the most popular choices for UK homeowners — especially those with terraced or semi-detached properties. It offers a straightforward and cost-effective way to transform your loft into a bright, spacious living area.
What Is a Rear Dormer Conversion?
A dormer is a structural extension that projects vertically from the slope of a roof, creating extra headroom and usable floor space. A rear dormer is built exclusively on the back slope of the roof, leaving the front elevation unchanged — helping to preserve the home’s original street-facing appearance.
Key Features
- Flat roof design is the most common, although pitched versions are also available
- Typically spans most (or all) of the rear roof slope
- Allows for full-height ceilings across much of the loft
- Often includes large windows or Juliet balconies to maximise natural light and airflow
- Ideal for adding a bedroom with en-suite, home office, or hobby room — tailored to your lifestyle
