Bundesnotarkammer Signs 15-Year Lease for 7,600 Sq. M. at The Tailory in Berlin-Mitte

CELLS Group, acting on behalf of the owner, has leased approximately 7,600 square meters (about 81,806 square feet) of office space and 12 parking spaces at The Tailory in Berlin-Mitte to the German Federal Chamber of Notaries (Bundesnotarkammer), the firm announced. The 15-year lease covers the building at Oberwallstraße 6, with handover of the premises scheduled for spring 2029. Cushman & Wakefield brokered the letting.

Lease Terms and Property Details

The lease runs for 15 years, to approximately 2044, and includes the 12 parking spaces alongside the office area. The leased space represents roughly 30% of The Tailory's total lettable area.

Oberwallstraße 6 is a Neo-Renaissance building in Berlin's Mitte district, constructed in 1891 as a clothing department store. Berlin's heritage register lists it as a protected historic building. It is part of The Tailory, an ensemble of nine historic and contemporary office and commercial buildings with about 25,000 square meters of lettable area. The complex comprises the addresses Oberwallstraße 6-7, Jägerstraße 27-33 and Taubenstraße 24-25.

A family office owns the ensemble, and CELLS manages the owner's property interests. The complex is almost fully let and follows a multi-tenant concept that includes office occupiers, a higher education institution, fitness facilities and food and beverage operators.

Adapting a Historic Building to a Modern Workplace Concept

The Bundesnotarkammer assessed its future workplace requirements and found they could be accommodated only to a limited extent in a conventionally configured existing property, according to CELLS. The company said it took on that challenge and worked with Berlin-based architectural practice mmrtg to translate the chamber's spatial and workplace requirements into a design concept for Oberwallstraße 6. The concept is intended to enable modern working environments within the building's historic fabric.

Dr. Markus Sikora, president of the Bundesnotarkammer, said: "The new premises will provide an excellent foundation for us to continue fulfilling our statutory responsibilities reliably in the years ahead. This includes providing digital services, such as the Central Register of Lasting Powers of Attorney, the Central Register of Wills and online notarial procedures, as well as supporting the work of the regional chambers of notaries and notaries throughout Germany. The modern workplace concept will create spaces for people to come together and encourage collaboration across departments. We are particularly pleased to be breathing new life into a historic building in the heart of Berlin."

Andrea Wlodarz, head of leasing at CELLS, said: "Letting Oberwallstraße 6 to the German Federal Chamber of Notaries represents a significant success for us. We are delighted to have secured a tenant that will help shape the long-term future of this distinctive location. The signing of the lease now paves the way for the transformation of the historic building and the creation of a future-oriented workplace environment."

Berlin Office Market Context

The letting comes as Berlin's office leasing demand shows signs of recovery while vacancy remains elevated. First-half 2026 take-up reached approximately 380,400 square meters, up about 52% from a year earlier, with vacancy at 10.5%, or roughly 2.26 million square meters available at short notice, according to Cushman & Wakefield data. BNP Paribas put first-half take-up at about 373,000 square meters and the vacancy rate at 9.6%.

Prime rents have also risen. Berlin's prime rent stands at €47 per square meter per month in Cushman & Wakefield's data, while Knight Frank reported €49 per square meter per month in the second quarter and expects full-year take-up above 600,000 square meters. Average rent stood at €28.50 per square meter per month.

Supply remains a factor. Colliers expected about 600,000 square meters of office completions in 2026, with just under 40% pre-let at the start of the year.

Outlook

With the lease signed, CELLS and the owner can proceed with the transformation of Oberwallstraße 6 ahead of the spring 2029 handover. The agreement adds a long-term institutional occupier to The Tailory, which accommodates a mix of office, education, fitness and food and beverage users.
