Jamestown, a design-led real estate investment and management company, announced today that Nattmann + Bruns Architekten has signed a lease agreement for the site on Schanzenstrasse, a historic creative office campus in the Cologne district of Mülheim.
In March 2026, the Cologne-based architectural firm moved into around 335 square meters at Schanzenstrasse 22 with 15 employees.
Founded over 30 years ago, Nattmann + Bruns Architekten specialises in residential construction and commercial real estate projects and serves a broad client base, including housing associations, private investors and retail chains. The company takes over all service phases of the architecture as well as project management.
"We chose the location in Cologne-Mülheim because, in addition to good accessibility from the city and the surrounding area of Cologne on the right bank of the Rhine, it offers a lively, refreshing neighbourhood that gives our office a good impetus," said Hendrik Bruns of Nattmann + Bruns Architekten.
"Schanzenstrasse was developed specifically for companies that draw energy from their surroundings – and Nattmann + Bruns Architekten is a perfect example of this," said Jessica Queißer, Senior Vice President Asset Management at Jamestown Europe. "With their specialization in the renovation of existing buildings and their energy optimization, they make an important contribution to our cities and at the same time embody the creative community on Schanzenstrasse."
The lease is the latest development on the Schanzenstrasse campus as Jamestown continues to invest in sustainable infrastructure. This summer, PLUQ will install eight public charging points for electric vehicles on campus, creating on-site charging facilities for the first time. In addition, Jamestown has concluded an agreement with hellgrün energie to install a photovoltaic system with an output of almost 100 kWp on the roof of Schanzenstrasse 28 – subject to approval by the monument protection authorities. Completion is planned for this year. The plant will be able to supply tenants directly with electricity on site at conditions below the market price. Jamestown is planning similar agreements for the buildings at Schanzenstrasse 22 and 24 in the course of the year.
Built between 1890 and 1914, the buildings at Schanzenstrasse 22, 24 and 28 served as the headquarters of the cable manufacturer Felten & Guilleaume for almost a century before they were converted into television studios and office space. Today, the approximately 35,000 square metre campus is an established location for media, creative and service companies in the Cologne district of Mülheim. The tenants include Brainpool, Banijay, Bavaria Entertainment, Positec, the International Film School Cologne and the TH Köln.
The post-industrial character of the buildings – listed brick facades, large windows, plenty of daylight and ceiling heights of over three metres – continues to attract companies looking for an inspiring alternative to classic office space. Felten & Guilleaume's historic director's villa at Schanzenstrasse 24 is currently undergoing extensive renovation and conversion into modern office space. From spring 2027, more than 1,500 square metres of exceptional office space will be available for rent. At Schanzenstrasse 28, one of the few remaining paternoster elevators in Cologne was put back into operation at the end of last year.
Jones Lang LaSalle advised on the transaction.
