About

SPG One is the only real estate agency solely devoted to luxury properties.

Whether buying, selling or valuing an exceptional property, SPG One offers its clients a global and personalized service. Its clients benefit from a direct affiliation to the SPG-Rytz Group which boasts over 60 years of experience, a sterling network and is a reference in real estate development, brokerage and management throughout French-speaking Switzerland. Buying or selling a waterfront property, a castle, an alpine chalet or a penthouse with a terrace is the fruit of a story born of an unexpected encounter, of a «coup de coeur» which, for some, is what dreams are made of.
It is a story that you and SPG One will write together.
