Velux loft extensions

A Velux loft extension is the simplest of all loft conversions as it doesn’t require planning permission – this is because the roof line of your home stays the same.

Rear dormer loft extensions

A rear dormer loft extension can often be done without planning permission, yet they significantly increase the floor and headspace for you, which results in a loft area that has greater usability.

Side dormer loft extensions

Side dormer loft conversions are a good option for semi-detached homes with hip to sloping side roofs. They offer a certain amount of extra headspace inside.

Hip-to-gable loft extensions

This is a conversion that involves changing the sloping side of your home, and as a result, means internally there will be more headspace, your loft area will feel bigger even though it still retains the same footprint.

Mansard roof loft extensions

This is an ideal option if you live in a conservation area, or need to ensure certain planning permissions are adhered to. The roof angle is changed to 70-degrees, the exterior will match your existing roof and more headspace will be created inside.
