A couple in Sheffield were astonished to discover a secret cellar beneath their home, which they estimate has added £70,000 to the property's value. Sophie Lane, 34, and her partner Matthew, 33, purchased the house for £375,000 in December 2025, unaware of the hidden space.
The property had been converted into two flats around 20 years ago, and the couple are currently renovating it back into a single-family home. In February 2026, while removing carpets in the downstairs hallway, they uncovered a hatch in the floorboards. Using a crowbar, they opened it to reveal a 23-square-metre cellar that had not been noted in the survey.
Sophie, a social media manager, said: 'When we opened the hatch and saw a massive cellar, so many things were going through my mind. We now have a whole other floor, our house could be worth £70,000 more now.' The couple plan to convert the cellar into a utility room and a movie room for their two children, aged four and 10 months. Sophie is also considering installing a slide from a hidden cupboard in the kitchen down to the cellar.
The couple believe there may be additional hidden space, as the current cellar only covers half of the house's blueprint. To investigate, they need to install a lintel to make the ceiling structurally sound before knocking down a wall. If extra space is found, Sophie plans to use it as a DIY workshop.
