Architectural Vision

FORTIMO AG

This project consists of three multi-family buildings, which will contain a total of 29 owner-occupied apartments and two commercial units. The apartments range in size from 2½ to 5½ rooms, catering to various demographics including individuals, couples, and families. Key features include open-plan kitchens with integrated exhaust systems, high-quality granite countertops, spacious bathrooms equipped with washing machine and dryer, and quality parquet flooring throughout.

Sustainable heating is facilitated through connections to a district heating network, enabling low CO₂ emissions. Renewable energy will be sourced from photovoltaic panels installed on two of the roofs, while electric charging stations for electric vehicles will be available in the underground parking garage if needed. Generous outdoor areas and thoughtfully designed landscaping provide an enhanced living experience.
