From photos, the lower ground floor apartment at St Mary’s Gate House, Nottingham city centre, looks like an ordinary property. Yes, there are not many windows, but there is a modern kitchen, exposed original brickwork, and an open plan living area. The two-bedroom flat is currently on the market for £300,000 with FHP Living.
In the lounge, however, is a glass doorway. Pass through it, and you will see a narrow set of stairs with a curved brick ceiling, leading mysteriously down below the building.
