Like the name suggests, Flat Roof extensions have… well, a flat roof!

Common in hotter climates because the roof doubles as living space, they have become popular in Western architecture. They are sleek and modern in appearance and are vastly durable.

Flat Roof extensions add more space to your home because the roof can become another part of the garden. If planning allows it, you can enjoy the summer sun in a deck chair with views of your own garden as though you’re on a balcony.

Another reason to opt for a Flat Roof is that they are economical; this is not indicative of a cheap product that lacks in quality, in fact, Flat Roof extensions are sturdy buildings that are made with quality products. More affordable than other extension styles mean you’ll be able to enjoy more space whilst spending less.
