Situated at the Kennedydamm, entrance to Düsseldorf’s inner city, ONE PLAZA together with the L'Oréal Germany headquarters and the vertical campus Eclipse, will add another impressive element designed by HPP Architects to the urban skyline. The mixed-use building with approx. 45,000 m² of gross floor area is to be realised for the MOMENI Group and, alongside its function as an office building, will also provide space for special uses, gastronomy and local services. With its characteristic facade, generous enclosed outside spaces, usable roof gardens and modern workplaces, ONE PLAZA stands for identity, sustainability and flexibility.
The building composition, consisting of three wings grouped around a central inner courtyard area, will create a sculptural entity with distinctive architecture and high recognition value. The dynamic design language is applied consistently across all the dimensions of the building, including the facade.
The two-storey elevation at each corner opens up ONE PLAZA on every side. Three generous entrance points are created which connect the ground floor area with the surrounding district. At the same time the height offset at the upper levels of the facade creates a striking roof landscape that offers protection from the wind for office tenants enjoying the gardens. “The diagonal lines of the curtain facade with its vertical, cleverly folded aluminium panels underlines the dynamism and lightness of the whole building and creates an intriguing play of light and shadow”, explains Volker Weuthen, HPP’s Senior Partner responsible for the project.
The building offers users a high degree of flexibility and the opportunity to implement every possible office concept from open plan to a cellular or combi office design. The permanent workplaces are arranged close to the facade. And in addition, in the central zones there are communicative working environments for flexible use with a range of options for employees. The enclosed courtyard serves as an internal meeting place, a central green lung, which, together with the roof gardens, increases the ecological quality of the building and creates a link to the open spaces of the surrounding area.
The fluent and naturalistic design of the open spaces is in powerful contrast to the sharp-cornered and highly compacted building design. Inspired by the leitmotif of “forest home”, the greening of the outdoor spaces, courtyard, roof terraces and sloping roof areas creates an urban oasis that lends added value to the working environment of users as well as increasing the urban quality of life of the neighbourhood. The additional green areas will have a positive impact on air quality, microclimate, heat and noise pollution, as well as comfort and well-being.
Besides these measures, many other green building criteria are fulfilled, so that ONE PLAZA is aiming to obtain both LEED Gold and Wired Score Platinum certification. Sustainable mobility is supported not only by the very good links to the public transport network, but also by electric charging stations and the unusually high number of 180 bike parking spaces, which are also available for the public to use.
Completion is scheduled for the first quarter of 2025.
