Any questions?
We are proud members of the hup! partner network. Choose us as your trusted hup! experts
Is a hup! extension really faster than a traditional build?
Yes, typically around five times faster, with most projects watertight in under a week. Rex fits factory-manufactured hup! wall panels rather than building brick by brick on site, so a Maidstone extension moves through the build phase far quicker than a traditional one.
How energy efficient is a hup! extension?
hup! extensions carry a wall U-value of 0.17, making them five times more energy efficient than the average UK home. For Maidstone properties, this often means a noticeably warmer extension in winter compared with an equivalent traditional brick build finished to standard building regulations.
Does Rex manage the whole extension project?
Yes, Rex acts as a single supplier for the entire hup! project, from initial quote through to completion. The hup! system is also pre-approved by leading Building Control inspectors, which removes the need for a separately appointed architect on most projects.
