Leading architect Laura Jane Clark from BBC’s Your Home Made Perfect, loves hup!

Laura Jane Clark is renowned for helping homeowners extend their homes with amazing results on the hit BBC TV show. She’s extremely impressed by the hup! system.

She says “Basework is usually the biggest minefield and the biggest headache for homeowners, so having something where you can use the existing base, and don’t need to start digging down and just build, getting watertight in two or three days, it’s an absolute game changer. The quality and level of detail is extremely impressive – from the engineering of the panels which make it extremely quick to build and energy efficient, through to how easy it is to add the finishing touches, which offer homeowners complete design flexibility. There is nothing that hasn’t been considered, and it takes away so many of the headaches associated with a traditional extension.”

 “hup! will make getting sustainable, energy efficient, hassle free and beautiful home extensions so much more accessible for homeowners – plus they can be built so much faster than traditional building techniques. What’s not to love?”

"I've been totally blown away by the engineering behind the whole thing."
