CELESTE, (forthcoming realisation: 2025-26)

* Project in collaboration with Doris Lasch

An open greenhouse in the middle of the public square evolving throughout the years and over the seasons

In the neighbourhood courtyard between Jupiterstrasse and Sternenweg in Reinach, a topography inscribes itself
into the context. A two-part architecture made of steel is located at the southern end of the perimeter. One side of
the architecture is surrounded by an island of vegetation. The architectural structure is made up of partly hexagonal,
geometric shapes. It suggests a dome-like building consisting of two fragmented parts. The structure is reminiscent
of a pavilion or the remains of a glass house. It is a romantic, utopian place that combines nature and architecture,
as well as the present, past and future. Despite its utopian nature, this installation plays a social role by offering va-
rious meeting places in the form of modular benches scattered around the park.
In the plant part of the greenhouse, different temporal levels intersect within the micro-landscape. The 'picture' pre-
sented also changes with the changing seasons and the passing of the years. The protagonist of the vegetation will
be a downy oak, which is a deliberately slow and unconventional growing tree.

Six models of flying objects suspended from the ceilings inside the school. Each object representing the six years
of the primary school and six different way of flying: technically, physically and mentally

Six large models of flying objects hang in the corridors of the new primary school in Allschwil. The six models relate
to the six years that pupils spend at the school during their education and represent six different ways of flying or
hovering: on the one hand, through technology, such as the first motorised aircraft Eole, invented by Ferdinand Adler
in 1894, the first hot air balloon Montgolfière, developed by the Montgolfier brothers in 1783, or on the other hand,
naturally "flying" or hovering like a cloud (cumulonimbus) and finally, flying through the imagination as in the myth
of the flying carpet. Each model is accompanied by a didactic board with a explanatory text and an illustration.
In this project, the children are invited to think about and consider the different ways of flying and escaping gravity:
through technology, imagination or by observing certain natural phenomena.

Silhouette of an emergency staircase

A spiral staircase leads from the terrace of the cantonal emergency centre to the roof. However, the metal staircase
is cut out of a steel plate and its supposedly three-dimensional character is actually a trompe-l'oeil effect, a 'picture'.
Like a sign, the fire escape here represents the primary functionality of the building and takes up an architectural
element that becomes a widely visible and identifiable ornament, while retaining its narrative character.
