What Is an L-Shaped Loft Conversion?
An L-shaped loft conversion is designed specifically for properties with a rear addition or outrigger – a common feature of Victorian and Edwardian terraced houses. The conversion involves building two dormers: one on the main roof and one on the outrigger roof, creating an L-shaped floor plan that follows the footprint of the property below.
This type of conversion maximises the available loft space in properties that would otherwise have a relatively small, awkward loft area. The result is typically a large bedroom with a separate en-suite bathroom, or a bedroom plus a smaller additional room.
Which Sheffield Properties Suit
an L-Shaped Conversion?
L-shaped conversions are particularly well-suited to the many Victorian and Edwardian terraced properties found across Sheffield’s popular inner suburbs, including Nether Edge, Sharrow, Meersbrook, Crookes, and Walkley. If your home has a two-storey rear addition (the outrigger) that creates an L-shaped footprint when viewed from above, this type of conversion is likely your best option for maximising loft space.
