Modern House Extensions
A few of the garden room firms we feature on this site will build house extensions. Often referred to as flat-pack extensions, these highly insulated structures are manufactured off-site and then delivered to your home for quick assembly.
These firms will work closely with you to design an extension around your home and your intended use.
A flat-pack extension is one of the quickest ways to extend your home. Your new room can be built and ready to use in just a couple of weeks.
