Common Types of Loft Conversions - What’s Right for Your Home?
At Art & Build Ltd, we design and build all major types of loft conversions to suit different roof structures, budgets, and planning requirements. Whether you’re in London, Surrey, Kent, or the surrounding areas, we can help you unlock valuable living space in your home.
Here’s a breakdown of the most popular loft conversion types and what they typically cost in the London area.
Dormer loft conversion is the most common and versatile type, suitable for most pitched roofs. It involves extending the roof vertically to create a flat-roofed box-shaped structure.
Best for:
- Bedrooms with en-suite
- Home offices
- Maximising head height and floorspace
Benefits:
- More usable internal space
- Often falls under permitted development
- Ideal for terraced and semi-detached homes
Estimated cost in London:
- £50,000 – £70,000+ (including en-suite and full fit-out)
An L-shaped dormer is a variation where two dormers are joined at a 90-degree angle, creating a larger footprint — ideal for Victorian and Edwardian properties.
Best for:
- Multiple bedrooms
- Studio flats
- Rental conversions (e.g. for Airbnb or lodgers)
Estimated cost in London:
- £60,000 – £80,000+
This type replaces the sloping side of a hipped roof with a vertical gable end, creating more internal space. Often combined with a rear dormer for even more room.
Best for:
- End-of-terrace or detached houses
- Gaining full staircase access
- Creating master suites
Estimated cost in London:
- £55,000 – £75,000+
A mansard conversion dramatically changes the roof shape by raising the party wall and altering the rear slope to a near-vertical angle.
Best for:
- Maximising space in period homes
- Properties in conservation areas (with permission)
- Long-term value increase
Estimated cost in London:
- £65,000 – £90,000+
This is the most budget-friendly option, using existing roof space without altering the roofline. Ideal if full head height is already available.
Best for:
- Home offices
- Guest bedrooms
- Budget-conscious projects
Estimated cost in London:
- £30,000 – £45,000+
