What are the Benefits of a Flat Roof Extension?

When it comes to extensions, the type of roof is a crucial element to get right. A flat roof is a popular choice for many types of extensions. Firstly, it is a cost-effective solution as building a flat roof requires less structural engineering than other roof types.

The compact streamlined shape of a flat roof exudes modern style, so it blends well with contemporary buildings. Finally, the flat roof shape is well-suited for flat skylights and roof lights. This makes flat roofs a great option for those who want to bring in more natural light and create a brighter living space.

At Plus Rooms, it’s our job to offer professional guidance so you find your perfect choice of extension. Once you’ve settled on your ideal extension we’ll bring that vision to life, revitalising your current space with a combination of design flair and functionality.

All of our extensions are bespoke, so we can go beyond offering just extra living space, and design brand new multi-purpose spaces for customers to use however they desire.

As well as designing and building your flat roof extension, our team can also provide planning services. By handling applications for planning permission and advising on matters such as party wall agreements and permitted development, you can have peace of mind that your new extension complies fully with building regulations.

There is no set cost for a flat roof extension. While roof types are indeed an important cost factor, the final cost of your extension will also depend on size, as well as what particular type of extension you are looking for.
