Dormer loft conversions are ideal if you want to add lots of extra space to your home. Adding a box-like structure or structures to the roof, you essentially extend the roofline to add significant square footage to your loft space. This makes dormer loft conversions one of the most popular loft conversion types, as they're ideal for adding a new main bedroom with en-suite or even a self-contained living space.
