Façade planning for the new Drei Tannen nursing home in Wald

The plans for the new Drei Tannen nursing home in Wald included a number of highly demanding structural and design features. After the completion of the project planning phase, EBP helped the developers prepare the documentation for the call-to-tender for the building’s façade and a mockup of the façade. We also monitored construction quality at the site throughout the project execution phase.

The Zurich-based architectural firm kit Architects assumed responsibility for the project’s execution after it prevailed in the architectural design competition for the new nursing home. Owing to the complexity of the design, EBP was commissioned after the project planning phase to assist in the planning of the façade and to draft all of the necessary documents for the call to tender for the building’s envelope.

A sophisticated building envelope

The façade is characterized by multiple prefab and sandblasted concrete elements that narrow from top to bottom at an angle to the façade. These elements also include shaped lateral features. This made it necessary to precisely cut or adapt all of the insulation units (RF1) behind the elements to measure. Given the concrete elements’ unusual center of gravity, planning for the necessary suspension elements and retainers proved especially challenging.

Functional aesthetics

The transparent surfaces were created with large-format, wood-metal window frames in oak and aluminum. Balustrades with alternating inwardly and outwardly curved, vertical steel bars serve as window-fall protection. In an effort to ensure that the various high-quality structural components would harmonize with one another in form and function, a functional mockup was built at the site.

Room-high window frames in wood and aluminum with a fire-resistance rating of EI30 ensure ample natural light in the two inner courtyards.
