Types of loft conversion

Buying a new house in today’s economy isn’t possible for everyone. So what do you do when you need more space? Most houses in the UK have an attic or loft space, often only used for storage and insulation. Lofts are a great opportunity to create a new room for various purposes. Transform a dusty space into a new bedroom, home office, or games room. As well as adding more space, they also increase the value of a house. Plus, this type of renovation is far less disruptive than a full extension. There many types of attic conversion. But the three you are likely to consider are dormer, roof light, and hip-to-gable. Which one you opt for will depend on the space available and what you want to use it for. 


Dormer lofts add both extra head and floor space, with vertical walls and horizontal ceilings just like any other room. From the outside, it looks like a right-angled triangle attached to the side of a pitched roof.

Roof light

Roof sky light conversions require little actual construction, but more renovation of the internal space to make it liveable. With the addition of roof light windows to allow natural light in, you can create a light and beautiful room.


Some houses have hipped roofs, meaning every side of the roof is slanted. Hip-to-gable requires one of these sloping sides to become vertical, opening up the inside space. This type of conversion only works for semi-detached or detached houses, since it requires a hip end. 

​​​​​​Do I need planning permission?

Most roof and loft conversions don't need planning permission due to permitted development rights. You might need planning permission if the planned design exceeds limits or extends past the current roof space. We suggest you check with your local planning department to be sure. You will definitely need to comply with building regulations. If you're not the homeowner, you’ll need to obtain permission from your landlord.
