The headquarter of the Deltabloc company was built in southern Lower Austria in the small town Wöllersdorf. Deltabloc is the world's leading supplier of concrete safety barriers and is part of the Kirchdorfer Group. Therefore, concrete as the design-defining material was an obvious choice. The elongated, two-storey monolith extends along the main road over the entire length of the property. The building is functionally divided into 2 zones - office wing and workshop. This division can also be seen in the different design of the outer facade. The strict vertical structure is reflected in various elements such as concrete pilaster strips, railings and the surfaces of the interior glass walls.
The basic structure of the building consists of concrete columns, cavity walls and element ceilings manufactured by Kirchdorfer Concrete Solutions itself. The office section is encased by a dark glass façade, in front of which sits a contrasting, strictly vertically structured concrete pilaster strip façade, which was also produced by the client. Sandwich concrete elements were used for the walls of the workshop wing with a vertical matrix profile as the surface. The two functions stand out from each other and still form a unit due to the common vertical facade structure.
These vertical elements are only interrupted by the entrance zone. The axis of the entrance is taken up by a long external staircase and emphasized by a façade incision on the opposite street front. This defines the lobby and reception area inside. While the outer facade is dominated by cool materials such as glass and concrete, the interior counters this with warm and muted color worlds. The lobby continues on the upper floor via the staircase, which, as a space-defining design element, resumes the client's production area. The staircase is a precast concrete part - manufactured precisely and with high quality. The stair railing repeats the vertical motif and is continued on the upper floor in a curved gallery railing. The amorphous form of the gallery forms a contrast to the prevailing orthogonality and creates an exciting spatial structure.
The offices are arranged in the elongated building on two hips, east and west. This long central aisle is interrupted by inserted boxes for various general functions (elevator, toilets, storage). This division is repeated on the upper floor, whereby the office part is split up on the west side and the area is used by a spacious lounge including a kitchen box. Warm gray tiles in the general areas, mottled gray carpet in the offices, oak for the wooden boxes and wall cladding in the corridor area, rough plaster with a brushed surface on the plasterboard partitions and warm yellow and orange of the seating in the general area ensure a feel-good atmosphere in the interior.
