Flat roof extensions are one of the most common forms of home extensions in the UK. This is because they are generally easier to build, and are thus cheaper, than pitched roofs. Another reason flat roofs are popular is that they can give a more contemporary feel. However, there are disadvantages, such as a high level of maintenance and it does limit the height of your new extension’s ceiling.
Flat roofs are ideal for small structures as they save space and, contrary to what most people believe, a flat roof should always have a slight pitch to enable rainwater to drain. If you decide to opt for a flat roof, it is still possible to install design features such as skylights and light wells and you may even be able take advantage of the design to create a roof terrace – giving you more outdoor space.(This will need to be specified during the design process and is subject to planning approval.)
For inspiration on how your London flat roof extension could look, take a look at our case studies below:
Rosebery Road, Haringey
This North London home has been transformed with a flat roof side return extension. Light wells, made of reinforced glass, were installed to ensure that plenty of light penetrated the room. The extra space has been used to create a large kitchen diner and a roof terrace on top of the extension roof. This feature has also allowed more natural light to enter a pre-existing bedroom.
