Kleihues + Kleihues is an internationally successful architectural firm operating in the range of architecture, general planning, urban design, interior design and landscape planning. The history of the office goes back to the founding year 1963. Today Norbert Hensel and Jan Kleihues are leading the company as managing partners, with offices in Berlin, Münster and Oslo/Norway. With decades of experience in planning and the realization of complex construction projects, we offer unique architectural solutions for cultural buildings, office, hotel, residential, education, retail and health. The functional attributes of our designs and the durability of the construction are the basis for an economical, as well as ecological use of available resources. As such, our office attaches great importance on selecting appropriate materials and ensuring handcrafted quality of all construction work – down to the smallest detail.
Kleihues + Kleihues is a full-service architectural firm active on a national and international level in the fields of architecture, urban planning, interior design, landscape planning and general planning, be it in the public or private sector. We offer extensive expertise and services for all kinds of complex projects – from initial to detailed design as well as the realization of projects, including BIM and construction site management. Some of the offices internationally renowned projects include the Museum of Contemporary Art in Chicago and the design for the Revolution of Dignity Museum in Kiew, Ukraine. In Berlin, the office has realized several exclusive 5-star-plus hotel projects including the Sofitel Hotel – along with the entire interior design concept - as well as the Maritime Congress Hotel. Additional national prestige projects include the Kaufhof flagship store at Alexanderplatz and the HQ of the Federal Intelligence Service, the largest project of the Federal Republic of Germany after WWII with over 260,000 sqm GFA.
The design is characterised by the height gradated
form and the three sweepingly spread star-shaped
building sections. The result is a series of surfaces with
varying lengths which bring rhythm into the approx.
120-metre-long façade. This formal consistency allows
a well-proportioned, nonhierarchical building ensemble
to be created, which assigns a clear identity to the user
in both multi-tenant and single-tenant letting. Two
circulation cores can generate connected areas of up
to 2,500 sqm.
With its very central location, the “Old Police Headquarters” site is of outstanding importance. The defined mix of uses for the development area lays the foundation for a vital urban quarter - a finely balanced system of public and private spaces. The unusual location of the high-rise building in the interior of the area is met with openness and permeability. The buildings form a playful ensemble. Rounded corners and slightly folded volumes support the flow of the rooms.
The department store "Galeria Kaufhof" at Alexanderplatz, planned and realised in 2004-2006 according to plans by Kleihues + Kleihues, is to be supplemented by a 134m high high-rise tower and an 8-storey extension of the existing building. The uses are independent of each other and are largely accessed separately. The high demands on inner flexibility and general sustainability are taken into account in the planning – they range from a smart façade to weight-saving cap ceilings.
