Thriller starring Gugu Mbatha-Raw, David Oyelowo, Jessica Plummer and Ben Hardy, adapted by JP Delaney from his bestselling novel. A young woman gets the chance to move into an ultra-minimalist house designed by an enigmatic architect, with just one catch: the occupants must abide by his list of exacting rules.

Production design drew on minimalist Japanese architecture to create the main location, 1 Folgate Street, in the studio. Interior furnishings and cantilevered stairs were all made bespoke. Rain bars in the main courtyard enabled water to pour down as if it was raining, with an extraction tank beneath providing drainage (source: Dezeen). Bristol Film Office assisted with the construction of an exterior façade in Redland, and other filming locations in the city.
