Terresta

What Terresta does

Terresta AG is a Swiss real estate management company headquartered in Winterthur, operating as the taxable real estate subsidiary of the non-profit foundation Stiftung für Kunst, Kultur und Geschichte (SKKG), founded in 1980 by Bruno Stefanini. The company manages a portfolio of over 200 properties containing more than 2,200 apartments and approximately 60,000 square meters of commercial space, with concentration in Winterthur and additional holdings across the cantons of Zurich, St. Gallen, Aargau, and Vaud. The portfolio spans heritage assets (castles such as Schloss Grandson, medieval altstadt buildings, industrial-revolution-era structures) and mid-20th-century housing estates through to contemporary new-build developments.

Terresta's product surface covers residential property rental (primary offering), commercial and retail space rental, parking and garage rental, hobby and storage space rental, in-house property and facility management, and property renovation and development (both occupied-state renovations and new construction). Distribution occurs through the company's own website and the Flatfox third-party Swiss real estate marketplace; marketing is supported by a corporate magazine, multiple newsletters, and a LinkedIn presence. Revenue is generated almost entirely through recurring monthly rental income, with net rental income of approximately 44 million CHF in 2025. Pricing is governed by a non-profit mandate: Terresta deliberately keeps rents affordable and passes on only about 50% of legally permissible rent increases following renovations, with 94% of apartments classified as affordable per the SOSDA benchmark.

In January 2026, Terresta Immobilien- und Verwaltungs AG and Belplan Immobilien AG — the two prior SKKG operating subsidiaries — merged retroactively into a unified Terresta AG, simplifying the corporate structure so that the new entity is both owner and administrator of the portfolio. The company employs over 70 staff covering portfolio management, development, construction representation, administration, and craftspeople. Strategic capital deployment includes a planned investment program of up to 1 billion CHF over twenty years to modernize the portfolio, with major active projects at Château de Grandson, Burgstrasse, Binzmühlestrasse, Zypressenstrasse, and Hohlandstrasse.
