Dormer loft conversions are a sensible, straightforward and often inexpensive way to add extra space and increase your property value. With a successful layout arrangement and beautiful design, your loft could be transformed into a comfortable living space to capture space and light. By building a new floor through a dormer loft conversion, you can add comfort and value to your home.

Our clients had a clear vision of how intelligent layout arrangement and beautiful design could transform into a spacious, light-filled sanctuary. They were keen to create a stylish dormer loft conversion as a private sanctuary from family life with a master bedroom and bathroom – a space to escape from the world.

Before & After

Existing roof plan of the property in Lewisham, London


Like many Victorian houses, this was built with a two-storey section sticking out into the garden, technically known as an outrigger. So we proposed adding an L-shaped dormer conversion, one dormer to be built on the rear roof and the other on the main roof, giving it an instantly recognisable L-shape. This is a great way to maximise space, especially for a mid-terrace property.

Loft conversions have to be treated as more than just a box on a roof. They are to be the successful addition to your property that you want them to be. For this reason, we proposed a compelling loft conversion design to capture space and light, and a beautiful mix of neutral colours with vibrant green.

With the addition of the dormer loft extension, the new second-storey layout incorporates the master bedroom and bathroom and multi-functional office space with elegant neutral interiors throughout. By creating the dormer loft conversion, the original master bedroom became the children’s playroom, and the new master bedroom and bathroom and study gave the parents a space to work, relax and escape.

Our client’s family life became less stressful and their property value increased significantly. With an entirely new level made possible by our involvement from the planning permission stage to the construction stage, we showed that loft conversions don’t have to be pokey, dark and lacking in style.
