Green Typologies - Illegal Trees

“Illegal trees” are defined as those growing so close to a building. Consequently, they relate the architecture and the open space at a new interface: the architecture is extended by the tree canopy, the building is greened while the outdoor space is redefined by the tree placements.

With the help of mapping processes, we will identify and categorise such trees in Munich's urban space, define influencing parameters and their typologies. Then, we will have a closer look at 5 selected cases, and derive patterns regarding the growth process, function, shading or atmospheric effect in the interior as well as in the exterior space. Since there are few purposely built/ planted tree facades in current urban and green planning, we will do research about trees that accidentally grow close to buildings.

The findings are graphically processed and presented with the help of various tools, media and formats. Finally, a 1:100 model of the most interesting case will be built to illustrate complex interactions between the tree as part of Urban Green Infrastructure, the building with its façade and foundation and other facilities (i.e., underground pipes, U-Bahn). The tasks of the seminar will be worked on in groups of 3.

The seminar is designed for both architects and landscape architects and aims to integrate the two disciplines.

It is possible to take the subject as a BA Landscape Architecture 7 project. An extended description can be found in TUM online under Project Landscape Architecture 7, Number: 0828


Prerequisites (expected knowledge):

Knowledge from lecture & seminar Green Technologies is mandatory. Interest in green architecture topics and graphic methods should be present.
