Types of Loft Conversions We Provide

Here are the most common types of loft conversions we do:

Roof Light Loft Conversion

This is the most budget-friendly and simple option

We don’t change the shape of your roof.
We simply put skylight-style windows (such as Velux) to allow natural light in.
It works excellently if you already have adequate head height in your loft.
It’s perfect if you’re having a good budget and require a bright, usable space like a small office or hobby room.

Dormer Loft Conversion

A very popular choice in many UK homes.

We extend part of your roof to create more space.
This gives you more headroom and allows in more light.
It can make your loft feel like a regular room in your home.
Great for adding a new bedroom, home office, or even a bathroom.

Hip to Gable Loft Conversion

Perfect for homes with sloped (hipped) roofs, like semi-detached or end-of-terrace houses.

We extend the sloped side of the roof to make a straight wall (called a gable).
This gives you extra floor space and makes the loft easier to use.
Time and again, combined with a dormer to create even more space.

Mansard Loft Conversion

This option gives you the most space, but it also involves the most changes.

We change the entire shape of your roof to create a flat or slightly sloped surface.
This creates a full extra floor of living space.
It’s ideal for terraced houses where space is limited.
Usually, you’ll need planning permission for this type of conversion.

If you are not sure which one will suit you best, we are happy to take a look at your property and guide you through the best options!
