The Grossmatt estate is centrally located within easy reach of shops, schools and public transport. The Grossmatt project comprises a total of five buildings, three of which were put up by bonainvest.

Two buildings accommodate a total of 19 owner-occupied apartments on four floors, while a third is home to 11 rental apartments, again on four floors. The first three floors each comprise one 2.5 room and two 3.5 room apartments. The top floor features two 3.5 room apartments with large roof terraces.

The project was built in cooperation with the Branschi Sattler Steiger Partner Architekten und Planer AG architects’ practice of Solothurn. In the Grossmatt project heat is generated by a brine/water heat pump. The apartments comply with bonacasa construction standards.
