Dormer loft conversions for maximum usability

Dormer loft conversions are one of the most popular ways to turn roof space into a genuinely liveable room. By extending out from the roof slope, a dormer increases headroom and improves the layout possibilities.

We design dormers to suit the property—balancing proportions, window placement and external appearance—so the conversion feels considered rather than bolted on.

Most dormers require careful structural and fire-safety design. We manage Building Regulations compliance and advise on whether planning permission is needed. If you are exploring your options, you can request a fixed-price quotation or browse recent work in our projects gallery.
