The classic town house is realized in transformational area with great potential to become a high-quality urban district with all amenities.
During the 20th century, the territory between the historical core of Hloubětín and Balabenka was used as a periphery of Great Prague, as an industrial zone with factories and warehouses. With the arrival of the new century, the area began to be gradually urbanized and transformed into a residential area of mixed character.

The house is not a solitary player, but part of the future urban structure. Based on the information of the territory, it sets logical and readable conditions for the houses that will stand around. It is easy to build on it, to connect it to the city block and thus create a concept of houses that build a living environment of the city street and create a protected area inside the blocks with greenery for its residents.

Highlighting the dominant corner flanked by Poděbradská and U Elektry streets is not realized by a facade element or "ornament" but by a material object, which is increased by two floor, from prevailing five to seven. The part of the house near Poděbradská street respect the street line derived from the already implemented development in the street. The part adjacent to U Elektry Street encloses the inner block environment and defines the street mass.

The architecture of the house is sober and purposeful. Clean and uncomplicated solutions are reflected in the minimalist concept of the facades, the material solution and the layout concept.

The building fulfills a mainly residential function located on the upper floors. Commercial areas are on the ground floor, accessible directly from Poděbradská Street. Parking and the building's technical facilities are located on two underground floors.

The building's total gross floor area is 9,573 m2, of which the building itself without garages and facilities makes up 7,429 m2. The building offers a wide range of 92 apartments in total, with sizes of 1kk (24), 2kk (52), 3kk (5) and 4kk (11). Parking for residents is mostly provided in underground garages with a total capacity of 77 spaces.

The technical solution is based on the optimization of supporting structures and external influences. It is a combined load-bearing structure using reinforced concrete ceiling slabs. Vertical load-bearing structures are a combination of reinforced concrete walls and load-bearing walls made of blocks. The perimeter shell is also formed by a combination of reinforced concrete walls and heat-insulating blocks. The stairs are made of slabs with prefabricated stair arms placed on the tooth. The roof is flat, covered with waterproof coating.

Due to the proximity of the tram and the busy road Poděbradská, the building is affected by vibrations. However, from the survey of the influence of vibrations on the considered object, no limits for the effects of vibrations in the object were exceeded. A vibration isolation measure is used on both part od the object and they are separated from each other at the neck.

The balcony slabs are solved by cantilevering with iso-beams. The loggias are designed within the ceiling slab without the use of iso-beams. A contact insulation system made of mineral wool in combination with EPS is used on the facades. Plaster of light natural shades is used as the surface layer of the insulation system.
