Some of the most expensive properties in the world can be found at the Bishops Avenue in London. This street is also called the ‘Billionaires’ Row and is located in Hampstead in north London with 66 exclusive mansions. Most of the mansions are uninhabited most of the year, however there are no savings made when it comes to maintaining the houses in a beautiful condition. There is also a lot of attention paid to the luxury of the residents. Thus, AWS have installed already several exclusive wellness facilities on this street.  
AWS designed a steam room and a sauna for this city mansion to complete the spacious wellness area comprising a swimming pool and a hot tub. The room style is minimalistic, discreet and soothing. Dark colours give the main tone. The walls, the benches and the ceiling in the steam room are finished with dark grey Venetian stucco and dark marble. The pale mosaics installed in the niche above the seats light up the whole room and the LED lighting creates an intimate atmosphere. The sauna timber was also stylishly varnished in black colour. The indirect Led lighting is installed in the false ceiling, under the benches and behind the backrests giving a special touch to the sauna. The dark marbled floor in the entire room creates unity. It fits in nicely with the aluminium frames of the doors, as well as with the edges of the pool and hot tub. Furthermore, the collection basin of the central ice fountain was also supplied in dark marble. The whole room looks simple and modest, but very stylish.
