Allreal is planning a residential complex with 17 semi-detached houses in Riehen BS

Glattpark, 31 May 2021: Allreal is planning a residential complex comprising 17 semi-detached houses to be sold as residential properties on Inzlingerstrasse in the Basel district of Riehen. Committed to delivering exceptional architecture, Allreal conducted a study contract involving three prestigious architecture firms based in Basel. A panel of experts headed up by Fritz Schumacher recommended that the project should proceed on the basis of the plans submitted by Buol Zünd Architekten BSA. The project is currently being finalised. Construction is due to start in 2022. The investment volume amounts to around CHF 53 million.

Allreal acquired the land in 2019. The Riehen community was keen to see nature conservation areas being created and some of the existing trees being preserved within the plans. These requirements were taken into account at the study contract stage. The aim was to bring an independent development to life, with the urban development, architecture and outside spaces at such a high level that the local area would really benefit from the new addition.

The panel of experts decided that the project put forward by Buol Zünd Architekten BSA best met the criteria for the study contract and unveiled the greatest potential. Even though the requirements were strict and clearly defined, the wide range of solutions offered up responded to the complex scenario in very different ways overall.

The planning application is set to be submitted in 2022, which is also when construction is due to start. According to the plan, residents will be able to start moving into the first timber-frame houses built to the Minergie-ECO standard in 2024.
