hup! Case Studies
Lucy's hup! Story
Lucy lives in a semi-detached 1930s home which the previous owner had occupied for forty years. When she bought the property, she was intending to complete a full renovation and wanted to gradually transform each room with more modern aesthetics.
A key part of her project involved adding a contemporary extension that she could use as an open-plan kitchen and dining area. Coincidentally, the innovative hup! building system launched just as she was about to start planning, and Lucy realised it was perfect for her.
Sarah's hup! Story
Homeowner Sarah Walsh and her partner Steven were keen to transform their existing conservatory. It was looking outdated and needed a refresh, and the innovative hup! system was the perfect choice.
The old conservatory had been neglected and unused for years, and the polycarbonate roof and dwarf walls felt disconnected from the contemporary style of their home. The sagging guttering didn’t help either.
