Dormer Loft Conversions

A Dormer loft conversion is one of the most popular and practical ways to create more usable space in your loft. It involves extending a section of the roof vertically, usually to the rear, to form a box-shaped structure with full head height. This instantly opens up the loft and makes it feel like a natural part of your home.

  • A typical Dormer conversion takes between 5 and 8 weeks.

  • Starting from £40,000.

Velux Loft Conversions

Also known as a Velux loft conversion, this is the simplest and most cost-effective way to transform your loft. There’s no structural change to the roof shape, instead, rooflight windows are fitted between the existing rafters to let in natural light and create a bright, open space.

  • A typical Velux conversion takes between 3 and 5 weeks.

  • Starting from £24,000.

Hip to Gable Loft Conversions

A Hip to Gable conversion changes the sloping ‘hip’ end of a roof into a vertical gable wall, increasing loft volume dramatically. This is ideal for semi-detached or end-of-terrace homes where the existing sloped roof restricts internal space.

  • A typical Hip to Gable conversion takes between 6 and 8 weeks.

  • Starting from £55,000.

Roof Lift Loft Conversions

A roof lift conversion is exactly what it sounds like; lifting the entire roof structure to create a taller, fully usable loft space. It’s the most extensive type of conversion and is used when your current loft space is too shallow to convert effectively.

  • A typical Roof Lift conversion takes between 7 and 10 weeks.

  • Starting from £55,000.

What are the roof requirements?

If you’re unsure whether your loft is tall enough to convert, there is one simple check to do.

The existing height from the top of the ceiling joists to the under side of the ridge needs to be at least 2.2 metres. This provides enough head room in the new loft space.

If your existing roof is less than 2.2 metres, we may need to utilise some specialist design methods such as dropped 1st floor ceilings, a roof lift or drop landing detail.
