» 02.01.2015 | 1st Prize Sustainable Parking Garage Competition |
Intep together with the team of HHF architects win competition for sustainable parking garage ex-tension with additional usage options in Basel, Switzerland

Project definition and outcome
The Christoph Merian Foundation has called upon six planning teams to propose a study on the extension of a parking garage located in Basel’s central Dreispitz district. The so-called “Parking & More” project aims to highlight cost-effective solutions for parking garage extensions as well as innovative usage ideas. The jury unanimously voted in favor of pursuing the project proposal submitted by the HHF architects team.

Expanding while reducing embodied energy
An architectural design integration approach allows the preservation and expansion of the existing building. As such, the infrastructural building extension makes efficient use of natural resources at reasonable building costs.

Flexible usage
Anticipating a long-term decrease in parking space demand, the design provides for taller stories and a slim vertical load-bearing structure to provide for additional usage options. Pop-up stores below and next to the parking garage as well as a motel built with wood elements on the upper levels, to be assembled and disassembled as needed, help animate the public spaces.

Local production and usage
The building’s vast roof space is used for urban farming as well as recreational uses and events, taking advantage of its sun deck and its spectacular view. Local products and fish are sold at the building’s neighborhood store or used by local restaurants, thus minimizing shipping while enhancing the residents’ identification with their neighbourhood.

Energy and water usage
The photovoltaic system on the event cube’s roof and parts of its façade covers 70% of the build-ing’s annual electricity demand. In case of high solar irradiation, excess electricity is used to re-charge electric car batteries. Rain water is stored in grey water tanks and re-used for toilets, car wash facility and the motel’s laundry.
