This is the most popular option. It adds headroom and floor space by building out from the slope of the roof. Great for larger bedrooms or a second bathroom.

A single dormer is ideal for smaller structures or where you want to add a compact room. It offers extra space without changing the roof too much.

This type runs the full length of your house, giving maximum interior space. It works well for large rooms or adding an en-suite.

Two dormers connected at a right angle are usually built at the rear of period homes. A great option for properties with rear extensions.

Built to the rear of the property, this creates a box-like structure. A great way to get more floor space while maintaining street appearance.

This extension has a sloped roof to match your current style. It suits homeowners who want to maintain a traditional look.

We extend the sloped side (“hip”) of the roof to create a vertical wall (“gable”). This gives more usable space inside.

With steep sides and a flat roof, this option creates the most internal room. It’s often used in urban areas where space is tight.

This design keeps your roof shape as-is, with added roof lights for natural brightness. It’s the least disruptive and most cost-friendly choice.

Many newer homes also qualify for conversion. We assess each property and advise on what’s possible, then handle the design and build.
