SPG-Rytz Group

« "The solidity of stone throughout the years" »


Société Privée de Gérance in Geneva was founded by Jean Paul Barbier-Mueller, a fine connoisseur of primitive arts and literature.

Société Privée de Gérance - which was to become one of the canton's largest property management companies - was specialized in the management of institutional rental properties and in the construction of social housing.



Business gradually developed thanks to modern management methods, a strong local presence, controlled diversification and company takeovers.

In order to galvanize sales and leases for its customers, Société Privée de Gérance developed innovative communication tools.


The first edition of the journal L' INFORMATION IMMOBILIERE was printed in 10,000 copies.

A true business card for Société Privée de Gérance, it is published three times a year and covers current topics related to the economy, politics, architecture, the arts, travel and culture. Being a quality journal, L'INFORMATION IMMOBILIÈRE today has a print run of more than 115,000 copies and ranks among the leading publications in French-speaking Switzerland.

Extension of international networks.

The SPG-Rytz group set up partnerships with Cushman & Wakefield and Christie's International Real Estate, world leaders in commercial properties and the upmarket residential sector.

The independent company specializing in commercial property consulting, SPG Intercity was founded by the group SPG-Rytz in French-speaking Switzerland and its counterpart Intercity Group in German-speaking Switzerland.
