This complex was built for a cosmopolitan clientele and was considered very advanced for its time. It had the most modern elevators and central heating of its time, and was furnished with luxurious fittings.

In its heyday, it was the meeting place for avant-garde of the cinema; it was frequently visited by such notables as Eisenstein, Room and Pabst and housed the headquarters of the publishers of the magazine Pool.

The redevelopment program has ensured that the spirit of the building has been retained, while all essential services have been replaced and modern technology added, for example: telecommunications systems, ventilation systems, elevators, designer kitchens, under-floor heating, new joinery, new plumbing and electricity systems, and so on.

Bordering the Riant Chateau is Rose Park, a beautiful park which extends to the Anglican church. At present an underground parking space is being built beneath Rose Park which is being re-landscaped and replanted with more trees for added privacy.

On the other side of the garden lies the Anglican church, and beyond that the terminus of the Mont Pelerin funicular.

Rose Park was a favorite haunt of the Austrian Empress Sissi, whose statue serves as a reminder to today's visitors. (See below).

The interior of the building reflects the extravagance and luxury of the Belle Époque, with high ceilings, elaborate cornices, inlaid mirrors, stained glass, heavy oak doors, and antique oak parquet floors.
