A dormer loft conversion adds a box-like extension with windows to increase headroom. This gives you flat walls and daylight, creating a practical room. It’s a versatile and popular style that expands the loft’s usable area.

A single dormer loft uses one dormer window, usually on the rear slope. It’s a simple addition that brings in light and space. Even with just one dormer, the once-sloping roof becomes a brighter, full-height room.

A full-width dormer stretches across the full width of the roof.
It maximises loft space and headroom. This gives you much more floor area in the attic. People use full-width dormers to create a large bedroom or open-plan room at the back. It’s ideal for making a big living area up top.

An L-shaped dormer combines a rear and a side dormer. It creates the largest extra space, spanning two sides of the roof. You might get multiple bedrooms or a very large suite. It is more expensive and complex to build, but it yields a truly stunning loft with maximum area.

A rear dormer loft is on the back roof slope. It’s very popular because it’s simple and effective. A rear dormer maximises headroom and floor area. It’s ideal for adding a bedroom or office at the back of the house without changing the front.

A pitched dormer (or cottage dormer) has a triangular gable and a sloped roof that blends into the original. It adds extra headroom and floor space in the attic. This type looks charming on older homes and lets in a lot of light, making the loft feel open and inviting.

A hip to gable conversion is for a hipped-roof house. We replace the sloping hip with a flat gable wall. This adds much more headroom and floor area. It essentially creates a large new end wall upstairs. Many homeowners choose a hip to gable conversion to gain a lot of extra space, often combined with a dormer.

A Mansard conversion changes the roof to a near-vertical wall on one side and a low slope on the other. It gives the most headroom of any loft type. A Mansard can add a huge amount of space, enough for large bedrooms and a bathroom. Because it alters the roof so much, it usually needs planning permission.

A Velux (Roof Light) loft conversion adds skylight windows to the existing roof. It’s one of the simplest, most affordable options. You keep the roof structure and just insert rooflights. This turns a dark attic into a bright, airy room. It often needs no planning permission (under permitted development). In a rooflight loft, we simply add windows without altering the roof shape. It costs less but gives the least extra floor area.

A new build loft conversion is done on a modern home. Many new homes have trussed roofs, which can complicate things, but it’s still doable. It’s perfect when a family grows or needs extra rooms. If you are living in a recently built property, converting the attic can add the space you need without moving. It often only needs permitted development permission, though some new estates have extra rules.
