Watch Zoe's hup! journey through the project! If your old conservatory is an unloved, unused, and uninspiring waste of space, it’s time to bring it back to life with hup!. While previously it has only been possible to replace the roof and the windows and doors like-for-like, with hup! you can use your existing base and convert your conservatory into a stunning new extension with a completely new layout. Place walls, windows and doors wherever you like in the design and the space will be warm enough to create a contemporary new open-plan living space.
