    What does an L-shaped loft conversion entail

    This type of dormer loft extension is ideal if you intend to acquire more floor space and headroom. It entails having two dormers that make for the L-shaped extension on your property. This can be achieved with certain property styles as the ones mentioned previously.

    Your home needs to have a rear extension for the L-shape to be possible. A two-storey rear extension provides an even better option when it comes to the L-shaped roof. You should ensure that your loft conversion has a minimum head height of at least 2.2m.
