Loft conversions in Cardiff
Turn unused loft space into an extra bedroom, home office, playroom or storage area. A loft conversion gives you more living space, a better-looking home and added value — all with minimum disruption to your family life.
Our loft conversion styles
We offer four styles of loft conversion. Each suits different homes and different goals.
Hip to gable
Extends the roofline at the side of a detached or semi-detached house to create a gable end. That creates more headroom and floor space inside the loft.
Best for: extra bedrooms, a bedroom with an en-suite, a walk-in wardrobe, an office, a study or a playroom.

Extends the roof outwards to add height, usable floor space and natural light. Flat roof dormers are quick to construct.
Best for: adding height and light where the existing roof limits headroom.

Like the flat roof dormer with the same benefits, but often more attractive because it matches a pitched roof. You can add more than one, depending on the property.
Best for: a traditional look that suits the existing roof shape.

The easiest type of loft conversion. The loft is not altered or extended, and Velux windows sit flush with the roofline. A good choice where there is already decent headroom or planning constraints.
Best for: lofts with existing headroom — cost-effective, quicker and with less structural work.
