Now that is most definitely the stair of the week.
What do you do when you have an historically designated building and can't disturb the walls and ceiling? Hogarth Architects designed it like a piece of furniture "to provide all the functions required by a man about town" on Queen's Gate Terrace in South Kensington, London.
"The space is located on the first floor of a listed building," explains project architect Hamish Herford in Dezeen. "The fire surround and cornice, by law, had to remain."
Herford adds: "The existing space was divided into three rooms with a false ceiling while the new design aims to restore the space back to its original proportions, which would have been as one room."
