Eggbuehl - Zürich

Following the strategic decision in 2015 to transform and develop the Eggbuehl site into a mainly residential property for the rental market, implementation is well on track. Construction at Eggbuehl, previously used for commercial purposes, began in early 2018 with the dismantling of existing structures and major groundwork. The energetic double-walled buildings were completed in the middle of 2021 and the tenants have moved into their apartments as well as the commercial areas.

It offers the oportunity to not only work inside historical buildings, but at the same time in modern office, business and commercial premises. It is situated within a short distance of the centre of Wohlen.
