we used concrete for its resistance, and were interested know out more about the ecological impact of our park. The planted rooms consist of about 400 trees: Lime trees, Beeches and Firs.​​​ Beaches absorb the most CO2, one tree absorbing 1 Ton of CO2 in 80 years. The total CO2 emissions (INCLUDING GReY ENERGY) of the concrete structures (including the wooden frameworks) averages 190 tons. We were able to estimate that our park would become carbon neutral in 40 years (2060) and would have a positive ecological impact from then on.
The three structures are inspired by classical typologies. By creating niches and framing the view, the visitors can choose between different perspectives to withdraw and observe
In the villa (former target structure) is situated at the highest point of our park, allowing visitors to gaze at Zürich. openings are created in both the directions of the forest and the botanical garden. 
the niches of the rotunda are oriented both inwards and outward through openings in the concrete slabs. The space can serve as meant as meeting point that can host representations and small events.
Niches placed along the path of the champs create the loggia. the running track crosses under the structure, creates a dynamic interaction between viewer and runner, with enter and leave each other's sight.
