Residential building Pasteurstraße 27, Prenzlauer Berg is the twenty-seventh article on projects from practice. The special aspect of this project is the new concept of a mixed-use residential urban design project of a high-rise form. The urban design project is located on the north side of Berlin in the Prenzlauerberg area. This architecture and urban development are part of the Berlin urban fabric that includes a large-scale block of small individual inward-looking buildings with a void courtyard in the middle. The urban design follows the typical urban fabric style of having a courtyard but not enclosed from all sides and the Wilhelminian style. The project was led by two architect’s firms and a group of aspiring homeowners. The development is made of two parts connected through an open terrace covered in all floors except the fourth floor. The urban design of this project focuses on creating multiple uses of the open space in the buildings and the plot boundary from the inside. The building connects to the adjacent open space between other blocks from the backside elevation of the ground floor corridor. It connects the open garden on the side of the building to the open space of the adjacent building in the first-floor pool area and garden. See Figure 1, the site plan of the project from Google.
The urban design and architecture of this development include 22 residential building units. A 7-story building having access from the main road and access from below the car park. The front side apartments have the main road façade and interior courtyard facade. On the other side of the building, the apartment has an interior courtyard façade and backside block view and access from the ground floor parking. On top of the apartment is the roof terrace. The underground parking has 13 parking lots. The 2 garden courtyards have a summer open kitchen. The residential floor area is 2800 m2. The building’s external form is typical from all building sides. See Figure 2, 3 of the front side and rear side photos.
The collaboration of investors which are identified here as shareholders, no developers or brokers making a saving of 25% of the total cost of the apartment price. All involved parties in the residential building and its construction participated from the plan design to selecting materials and even building types of equipment. See Figure 4 the internal courtyard of the rear side of the project showing the garden space.
The ground floor has four core areas, the open corridor connecting the residential building area blocks open space, the garden to the main road entrance, and the internal courtyard. From the main road entrance, a ramp gives access to the underground parking of the 13 parking lots and the vertical circulation to all the floors of the building by elevator and staircase. The interior courtyard garden is the centroid of the residential building. See Figure 5, right the development section through all its components.
In the ground floor plan of the residential building, it is apparent that the architecture firm combined different layouts for the building apartments as they are not all typical. Figure 6 the ground floor plan of all the development. The entrance area (7) includes the development entrance and the car park ramp to the underground 13 parking lots. The front elevation ground floor apartment has a different architectural arrangement, which we will see later, marked (1). The interior courtyard (2) connects all the areas of the buildings and entrances. The rear side part of the building apartment (5) is different from the front side. The corridor open space (3) connects the entrances and the rear blocks of buildings. The architecture firm included many bicycle racks on the ground floor (4) which are open to the garden side. The backyard garden (6) is open to all open areas in the residential building and blocks side buildings open space.
Figures 7 and 8 show the alternative architectural design of the ground floor apartment of this residential building. The architecture of the apartment varies in components in terms of number of bedrooms in the flat.
The fourth-floor plan shows that the front-side apartments are different in architectural design. The open terrace connects the front side apartments and the rear side apartments. The rear side apartment includes a two-story apartment in that the fourth-floor plan has bedrooms and the third floor has services like the kitchen and living and related functions. The upper part apartment is marked in red in Figure 8.
