Terreïs aims to expand, drawing in particular on the pool of commercial leases currently managed by the Foncia group's branch network and by acquisitions facilitated by this network's potential to introduce new opportunities.

For commercial premises, priority is given to those with uncapped rents (travel agencies, estate agencies, the liberal professions, etc.) in the most highly visited areas of the commercial centres of major cities.

For offices, Terreïs' strategy excludes high-rise buildings due to the operational constraints they bring. Instead it focuses on small Haussmann-style buildings in strong locations in Paris and, in the Greater Paris region and regional cities, on city centre sites of 100m² to 1 000m².
