HORTUS sets a new benchmark for sustainable construction
HORTUS, a new type of office building that focuses on radical sustainability, from construction to operation, has opened in Allschwil. The project is part of the Switzerland Innovation Park Basel Area and combines CO₂ reduction, circular economy and user comfort. The space is already almost fully let.
With HORTUS, a building has been created on the Main Campus of the Switzerland Innovation Park Basel Area that is set to set new standards in sustainable construction. The project was developed by SENN, Herzog & de Meuron and ZPF Ingenieure. HORTUS is not only conceptually designed for climate compatibility, according to those involved, it will offset its gray energy within a generation and then be operated as an energy-positive building.
The core of the concept is a consistent reduction in the use of energy in construction and operation. Materials such as clay, wood and waste paper were processed with minimal use of resources. A basement was deliberately omitted. At the same time, a photovoltaic area of around 5,000 m² on the façade and roof ensures maximum energy generation.
Circular economy at component level
Particular attention is paid to reusability. Every element used was planned with a second use in mind. HORTUS thus follows the principles of the circular economy down to the last detail. Prefabricated clay-wood elements, manufactured directly on site in a field factory, enable efficient dismantling or reuse.
Natural materials ensure a balanced indoor climate, supported by a green inner courtyard designed by renowned landscape architect Piet Oudolf.
Infrastructure for innovation
The building offers around 10,000 m² of usable space, primarily for companies from the ICT and life sciences sectors. The office space was already fully let when it opened. The only space still available is in the coworking area. This is aimed at start-ups, project teams or individual users who want to benefit from the proximity to one of the largest life sciences ecosystems in Europe.
The coworking space and the office areas have shared kitchens, a garden and IT infrastructure. On the first floor, catering facilities and a fitness area complement the infrastructure. The aim is to combine innovation and everyday life in one place.
Part of a larger development site
It is not the first building on the campus. The Main Campus HQ is already in operation. Other buildings, ALL, HOPE and SCALE, are under construction or in the planning stage. By 2029, Allschwil will be home to Switzerland’s largest innovation park, with a focus on life sciences, digital health and industrial transformation.
With currently around 1,200 employees in 92 companies and 12 research groups, the site is already an important center for applied research and development in Switzerland.
