Situated at the Kennedydamm, entrance to Düsseldorf’s inner city, this building, together with the L’Oréal headquarters and the vertical campus Eclipse, will add another impressive element to the urban skyline: One Plaza by HPP Architeckten

This project is part of LE3DERS exhibition at Valcucine | Milano Brera showroom during Milan Design Week 2022.

The mixed-use building with approx. 45,000 m² of gross floor space 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 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.

Separate from the thermal envelope, the curtain facade provides structural, external solar protection, thus reducing heat influx to the building in the summer.

Every second facade section has openable windows for individual ventilation. 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 glass facades. 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 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.

Added to this is the reduced water consumption inside and outside, technical building services optimised for energy usage through simulations and performance testing, and high thermal comfort combined with maximum natural light and presence-controlled sensor technology.

All materials will be selected by experts in the planning process after an examination of their environmental impact as regards their manufacture and constituents.

The existing building on the developed site was already dismantled last year. Work on the new construction will start in mid-2022, completion is scheduled for the end of 2024.
