Large and prestigious areas

The Square One business and residential building is the new and eye-catching flagship of the D4 Business Village Luzern. It is the location of choice for large areas covering whole storeys, small areas from 820 m² or entire floors up to 2,170 m².

Flexible options for expansion

Square One is Minergie certified and consists of a ground floor and six upper floors. It features modern, high-quality architecture, is highly space-efficient and offers a full range of opportunities to create a pleasant working atmosphere. The fit-out standard is customisable.

“With its proximity to our headquarters in Lucerne and its excellent transport links, Square One is in the ideal strategic location for us. We are able to offer our employees an attractive workplace in an up-and-coming economic region.”



In 2020, anchor tenant CSS Insurance will occupy one-third of the new Square One office complex. Around 250 employees will work here. The company’s headquarters will remain in Lucerne.
