Superimposing today’s building structures onto the historical plans reveals a series of gardens in various styles. A unique, romantic landscape garden stretches across the entire northern zone, from the Leonhardgraben to the Steinenengraben.

The current analysis of the music school reveals two distinct outdoor spaces: the main entrance from Leonhardstrasse, which serves as a forecourt marking the symbolic entrance to the campus and provides access to the building units on a single level. The second outdoor space, accessed via the Steinen- and Leonhardgraben, is divided into several levels by the most recent buildings.

In addition to the North and South courtyards, the garden at Leonhardstrasse 2 retains its character and distinctiveness. The design concept for the outdoor space is based on the contrast between the two courtyards. On one side is the entrance from Leonhardstrasse, which is more like a piazzale. It features a low-lying green space, accented by several large-canopied trees and a design language that creates a sense of unity along the access axis. On the other side is the northern courtyard, which evokes the original romantic garden. A nature-oriented design with low-maintenance landscaping and a dense tree canopy that blends with the existing vegetation on the Helvetia property, creating a harmonious atmosphere. A third, small-scale garden adjacent to the cafeteria features an attractive terrace. Surrounded by a diverse array of vegetation, it offers a soothing retreat in the welcome shade. It provides a deliberate contrast to the larger lawn area on the opposite side of the café.

An extensive grass esplanade reinforces the centrality of the access way to the courtyard. This area allows you to enjoy the sunny winter days in contrast to the rather cold north courtyard garden. A new lime tree (Tilia cordata) is planted in the centre and contributes to the zoning of the space by referencing the historic design and providing an attractive place under which to converse or listen to music.

The wooden deck under the canopy serves as a stage and seating area during the summer months. From that stage, music will enliven the café's outdoor seating area, which overlooks the south courtyard. The small-leaved linden will maintain its central position in the axis when accompanied by a round bench. In this way, the tree will have more space at its base.

A natural garden of great ecological value extends throughout the northern courtyard, including the new building over the existing library. The new building rises above the garden like a temple in nature above the roof of the existing library. A covered space allows for the flexible organization of outdoor events throughout the new addition, framed by lush vegetation. The staircase to the "temple podium" is interrupted at the entrance to ensure unobstructed access and zenithal light from the library, which is designed as a grotto.

The courtyard between the Vera-Oeri Library and House 5 will maintain its current state by illuminating the basement with light through the library's skylight, which will be enlarged. The entire courtyard will be filled with plants, eliminating hard surfaces. The rammed earth walls will reinforce the concept of the grotto. As a result of the humidity, it will be covered with a layer of moss, which will be visible from the reading areas of the library. At the rear of the grotto there is a small retention area for rainwater infiltration. Between the new building and House 6, a small stepped courtyard will bridge the height difference between the two entrances. Bicycle parking at the three entrances to the north courtyard completes the access from Leonhardstrasse.

Behind the space between houses 2 and 7 there is a small, well-kept garden. Located between facades, it creates an appreciated shelter. As a contrast to the large-scale design of the south courtyard, a small-scale hortus conclusus is created here, which can be used by the cafeteria. Existing trees and buildings attached to the garden will be preserved. The wall separating house number 2 from the garden will be removed.
