Why hup! offers a smarter approach to building a modern house extension

Discover why homeowners in Northampton and the surrounding areas are choosing hup! to build modern house extensions that are smarter, faster and more energy efficient.

Unlike traditional building methods, hup! removes many of the common frustrations associated with extending a home. Brick remains the default choice for many house extensions, but it isn't always the best fit for a contemporary house extension.

When compared with the revolutionary hup! system, that choice becomes harder to justify. Park Lane Windows combines local expertise with the benefits of hup! to deliver high-performance house extensions designed around modern living.

Lightweight advanced building technology icon

Lightweight

Lightweight advanced building technology

hup! walls are lightweight enough to allow many conservatory conversions to make use of the existing base, something that isn't usually possible when rebuilding with traditional bricks and mortar.

The lightweight panels used in the hup! system can be easily lifted and carried by our installation teams, helping to speed up the build while minimising disruption to your garden. With materials spending less time on site, your garden is protected from unnecessary damage during the installation process.
