Types of Loft Extension

The right structure for your roof

Dormer Conversions

The most common option, adding usable floor space and headroom by extending vertically from the existing roof slope.

Hip-to-Gable Extensions

Extends a sloped hip roof out to a vertical gable end, adding significant extra space on suitable properties.

Mansard Conversions

A more substantial structural change to the rear roof slope, often used to maximise space on period properties.

FAQs

Loft extension questions

What types of loft extension do you build?

This depends on your roof shape and what you want from the space, but common types include dormer conversions, hip-to-gable extensions, and mansard conversions. We'll advise on what suits your property at survey stage.

Do I need planning permission?

Many loft conversions fall under permitted development rights, but this depends on your specific property, roof type, and any previous extensions. We can advise on this during an initial consultation.

How much headroom do I need for a loft extension?

Building Regulations generally require a minimum head height, and we assess your existing roof space against this at survey stage before recommending an approach.

Will the extension include an en-suite or just extra floor space?

Either is possible — we plan the layout around what you want the room to do, whether that's an additional bedroom, a home office, or a bedroom with en-suite.

How disruptive is the build?

There will be a period of scaffolding, roof work and some noise, but we plan the sequence of work to minimise disruption to the rest of the property as much as possible.
