Administrative Building Rohan – River Garden

This is a concept of an office module and a natural composition of functions. The expression of the building is created by a sequence and rhythm of windows, portals, and colonnades. The building is an office object with a U-shaped floor plan with unevenly long arms measuring 78.3 x 31.7 m, with 8 above-ground and 2 underground floors, the 7th and 8th above-ground floors (hereafter NP) are set back in plan. Along "Rohanské nábřeží," there is a colonnade at the level of the 1st - 2nd NP with a depth of 3.8 m featuring a publicly accessible sidewalk. The building has two vertical communication cores with internal staircases and elevators. The 1st - 2nd underground floors are arranged as a half-floor and house parking spaces for vehicles, technical rooms of the building, and storage areas. On the 1st NP, there are commercial rental spaces for shops with separate entrances from the street and necessary operational and sanitary facilities. Entrance to the administrative part of the building is through two main portals to the receptions on the 1st NP from Rohanské nábřeží. The receptions are conceived as a raised simple yet artistically designed space (paintings by academic painter Markéta Jelenová), followed by the technical control room of the building. The 2nd - 8th NP are designed as hall office spaces of the "open space" type. Two economically designed communication cores are connected by common areas with sanitary facilities on each floor. Each administrative floor is further equipped with two tea kitchens. This allows significant variability for partitioning for individual companies. On the 7th NP, there is access to a roof terrace from the offices, created by the floor plan setback of the last two floors. On the 8th NP, there is access via a staircase to the flat roof, which is used for the placement of technological equipment.
In this project, the investor and the contractor have worked amicably towards a balanced and maximally rational standard by investing minimal resources, while still leaving room for at least part of the above-standard solution. This means that the ground floor features stone facades and a non-standard conception of classicizing, demanding quality environments in the entrance areas and adjoining facade elements. The overall arrangement thus alternates modernist architecture, "glass globalism" with Rohan standing out here with a sequence and specificity of a human Baltic conception, for instance, through the bodily rhythmization of windows, portals, and a city module colonnade with stone elements in the ground floor. The architecture draws from the minimal allowed by the basic portion of a generally understandable office module (1.35 - 1.40 m) and the natural composition of basic functions. The use of this system is closely tied to the architectural solution of the building, particularly the facade system, which also better allows for the interior's resolution without complex interventions. The entire economic solution is interconnected with the architectural design, structured to avoid unnecessary losses during client changes, thereby allowing the human internal environment to be shaped by the very essence of the design.
