Welcome, to the future of
modular home extensions

Brick and mortar extensions have evolved – why not extend your home the modern way with a highly flexible modular wall system with an expansive range of roof options,
windows and doors to suit your own unique requirements?

If you are considering a new home extension then why not consider the hup! system from Window Wise, providing a stylish, well insulated glazed living space to be used throughout the year.

Glazing can be incorporated to both the walls and to the roof of your chosen design, allowing natural light just where you need it.

Create your dream living space that is bright and airy along with your own unique balance of useable wall space and panoramic views.

Personalise your hup!


There are numerous reasons why Window Wise sees a hup! modular extension as being the ultimate home improvement.

Hup! really is the better way to build, offering the very best in aesthetics, energy efficiency, choice and accreditations.

Enhanced energy efficiency

Rising energy costs are a headache for us all, but hup! conservatories & extensions from Window Wise offer ultimate energy efficiency thanks to high performance glass, modular walls with extremely low U-Values (0.17*) and controlled use of solar energy.

One supplier, one project!

Providing complete project management, Window Wise will take care of everything!
A traditional brick built extension requires a whole range of tradesmen to complete. The team at Window Wise are able to take your hup! home improvement from the initial design through to the drawing and planning process, on to construction and completion.

Three ways to extend
your home with hup!

Build a new conservatory or glazed extension

Using the hup! modular system, we can offer the very latest in conservatory design and technology. With far more design options than conservatories of old, modern conservatories are stunning light filled spaces that are also a room for all seasons. This is thanks to high performance glass and the technology with the hup! walls and all of our roof choices.

Transform your existing conservatory

If you have ambitions for your old conservatory, then our hup! walls offer a simple solution. We can transform an old conservatory into a modern, energy efficient extension that feels like it is a true part of your home. The lightweight, energy efficient walls are quick, easy, and cost effective to build onto existing bases.
