Concrete Printing 3L

A garage with orangery for the aunt in Kaltern St. Nikolaus.
Sensitively integrating into the existing courtyard, creating space through demarcation and connection with the existing structure. Script-based design of perforated surfaces inspired by traditional hay barn architecture.

This project involves a garage with orangery built into the slope. By positioning it at a distance from the existing building, a covered courtyard space was created. The fountain was deliberately placed at the property boundary, marking the entrance. It becomes a meeting point and focal point of communication in the neighborhood.
The orangery was to be equipped with a large window opening and a fixed sunshade, allowing ample daylight into the room throughout the year while protecting against excessive direct sunlight.
The challenge was to create a sunshade that does not change, yet responds to the different positions of the sun and angles of radiation, to allow for sufficient or not too much light into the room throughout the year and at any time of day.
The 3D print we designed consists of three scripted layers, interwoven like a fabric.
The parameter-based layers can be adjusted by entering the position of the location and the associated position of the sun over the course of a year, so that the shape and resulting openings were modified to create optimal light entry.
In addition to this innovative parameter-based design approach, another new method of 3D concrete printing was implemented.
To shape the normally liquid material, formwork is typically required. Free forms, especially intertwined structures, are only feasible to a limited extent or with great effort. Through the applied "weaving technique," it is possible to give the otherwise solid material a light and freely formable appearance, imparting a special and new character to the interior as part of the architecture.
