Sonar Real Estate takes over management of Düsseldorf office portfolio

Sonar Real Estate has taken over commercial property management responsibilities for three office buildings in Düsseldorf’s Medienhafen district. The properties, known as ALTO, LARGO, and FLOAT, collectively offer more than 88,000 square metres of rental space and are part of CPI Europe AG’s portfolio. These buildings were completed between 2018 and 2021.

ALTO, located at Kesselstrasse 3, comprises approximately 36,050 square metres of space, while LARGO at Kesselstrasse 5-7 provides around 21,700 square metres. FLOAT, situated at Kesselstrasse 1, offers about 30,350 square metres.

Sonar has managed lease operations for these properties since October 2022. The new mandate expands Sonar’s role to include commercial property management, covering lease administration, financial reporting, budget planning, and coordination of external service providers. Diemer GmbH Baumanagement continues to handle the technical property management aspects for the three buildings.

All three properties have achieved LEED Gold certification and feature modern technology, high ESG standards, and amenities such as fitness facilities, dining options, a welcome desk, and 24/7 security services.

Nick Puschkasch, Managing Partner at Sonar Real Estate, stated that the expanded mandate reflects the company’s approach to integrated management services and strengthens its presence in large institutional property mandates. He noted that Düsseldorf’s Medienhafen provides a favourable setting for premium office properties due to its urban environment, infrastructure, and a tenant base focused on sustainable industries.

Julian Kaup, Managing Director at Sonar, added that the company offers a range of asset management, property management, and development services, enabling clients to tailor solutions for their properties. He expressed satisfaction that the original lease management contract has grown into a broader property management engagement.

The ALTO and LARGO buildings, designed by slapa oberholz pszczulny | architekten, include a 16-storey tower and a six-storey structure, both located along the Rhine and built with flexible layouts accommodating various office concepts and event spaces. FLOAT, designed by architect Renzo Piano, consists of six interconnected building sections and adds a significant architectural element to the area.
