Five times more energy efficient than the average UK home
Rising energy costs are a headache for us all, but hup! offers
ultimate energy efficiency thanks to high performance glass and
extremely low U-Values.

One supplier, one project

hup! is the hassle-free way to build. One familiar team takes care
of the whole project and there is no need for an architect. Your hup!
designer will help you visualise your design and provide a price that
will not fluctuate, giving you confidence that your beautiful extension
will be delivered on time and on budget.

Five times faster to build
What would take months to build with traditional methods will take
weeks with hup! and what would take weeks now takes days. Built in
any weather by one team, your hup! extension is delivered as a flat
packed kit so there is no cutting or waste on site, helping you escape
the mess and disruption associated with traditional builds.

Ultimate design flexibility
Choose from pitched roofs or flat roofs, all with rooflights that flood
your new space with natural light. Whether you want to frame your
view with large picture windows or create an indoor/outdoor space
with large sliding doors, hup! gives you total design freedom.

High quality finish, every time

With hup! a high quality finish is assured every time. Designed by
Ultraframe, the UK leader in extension and roofing technology, hup!
is manufactured in a BBA approved factory in Lancashire, and every
hup! extension features Ultrapanel technology that is patented and
approved by the BBA to a lifespan of at least 60 years.
