Berlin, Germany
Designed by Sergei Tchoban and his design team from Tchoban Voss Architekten and landscape architects from kre_ta Kretschmer Tauscher Landschaftsarchitekten Partnergesellschaft, the construction of AMANO East Side Hotel and office building is a new mixed-use development located in a 2,400 square meters plot in Friedrichshain-Kreuzberg district between the Ostbahnhof and the north bank of the River Spree.
The cubature of the buildings harmoniously fits into the listed, historical urban structure and continues the height of the eaves of the surrounding buildings.
The hotel part of the complex is of conventional construction with filigree ceilings and load-bearing walls of masonry or reinforced concrete.
The office building has a reinforced-concrete skeleton construction and a stiffening staircase core.
The clinker exterior façades give each part of the complex a dynamic appearance with its own distinct character.
The façade of the hotel is divided into alternating window fields that are separated by clinker bars with matt pastel and iridescent color patterns.
These emphasize the horizontal orientation of the building’s appearance.
On the north and south façades this regular, strict façade division is interrupted by the publicly accessible “window on the Spree.”
This has a glass façade on the ground floor overlooking Stralauer Platz
and the River Spree.
Facing the river, the façade grid is articulated by a single-story socle and a central
risalto.
The window bays on the ground floor and seventh floor have staggered recesses in the lintel area in addition to lateral flanges.
The second special element is the “sky terrace”: an equally wide, single-story, fully glazed opening on the north and south façades, which is a counterpart to the “window on the Spree.”
The façade of the office building, on the other hand, is vertically structured by continuous clinker brick bands in a red-brown color.
Horizontal clinker bars on every second story suggest double-height office floors.
The regular arrangement of the almost square window fields gives the façade a calm, generous character and alludes to the design of industrial buildings.
The main access to the hotel lobby is from Stralauer Platz. There is a second entrance in the “window on the Spree.”
In addition to the 174 rooms, a conference area for approximately 152 people, and the hotel bar on the ground floor, there is an extensively landscaped south terrace with access to the breakfast room facing the river.
The top floor has a roof terrace with a 131-m2 “Sky Bar.”
The other terrace areas on the second and seventh floors are non-accessible green roofs.
Access to the office building with lobby and the six office floors is also directly from Stralauer Platz.
The floors here have a clear height of approximately 3.05 meters and allow flexible use for open-plan offices, cellular offices, or mixed functions.
The non-accessible roof areas here are also greened. The east roof area on the second floor and the roof area on the sixth floor are accessible terraces for use by office staff.
The entrance to the underground car park is located at the north-western corner of the site in the vicinity of the office building and can be accessed from Stralauer Platz.
The two basement levels provide 50 parking spaces for cars and bicycles, five of which are barrier-free and 15 of which are for electric cars.
All public areas will be barrier-free.
