Treehouse Eilenriede

This treehouse is in a park-like garden with many trees directly adjacent to the inner city recreational area of Eilenriede in Hanover. Only a fence separates the property, which contains a large villa built in the 1920s, from the public park. In drawing up the design, our aim was to place the treehouse in a prominent position in the garden and to ensure that it afforded good views to the urban park. At the same time, the construction was to be as inconspicuous as possible and be hidden amongst greenery, away from the eyes of the public. The intention was that the treehouse would be solely supported by the trees themselves, without additional supports. The framework for this design is based on a radial footprint on two levels. The upper, fan-shaped terrace area and the slanting treehouse itself are held by two trees using cable constructions. While the oak is enclosed within the treehouse terrace, the hornbeam is freestanding.

The interior comprises a reclining area for three children, a bench opposite, and a folding table. The reclining and sitting areas and the cushions are covered with wool felt. Beneath them there are pull-out boxes made of dark, laminated plywood. All sides of the treehouse cabin are glazed, so that children and adults have a lovely view of the adjacent woodlands and, hidden behind boughs and leaves, can observe those jogging or strolling in the park without being seen themselves.
