A revolution in Extension and Conservatory construction​

Imagine that you could build a conservatory or extension that’s significantly more energy efficient than the rest of your house.

Imagine that instead of construction taking weeks as it would with a normal extension, it only took 4 days to be completely finished.

Imagine that it costs around 60% of the cost of a normal extension and would be cheaper to heat for the entire lifetime of the construction (which is at least 60 years or similar to traditional construction).

With a wide range of external designs and finishes to choose from, hup! is the most cost-effective, energy-efficient, stylish and convenient way to add space to your home. Visit our showroom and see it for yourself.
