The tree has a wooden beam- and columnstructure, which results in light and open spaces.
Technical ducts spread as veins through the tree.
The higher up in the tree, the bigger the levels become. Voids and stairs create physical and visual connections between the platforms.
The structure is based on a structural core — the stem of the tree. A two-directional beam-structure, in particular the beams resting on the core, form the main support for the hanging branches that give shape to the tree.
The calculation of the structure includes live loads from snow, wind, and library usage and dead load of the structure itself.

The resulting forces in the structural elements are considerable. We searched for an equilibrum between the size of the beams and columns, the type of wood used and the dimensions and form of the levels to obtain a structure that is visually pleasing and strong enough.
Catalogue of the structural elements.
Detail of the hanging supports, which don't have to carry much weight and can therefore be quite simple.
Detail of the connection between core columns and main supporting diagonals, which form one of the crucial points of the construction and therefore need to be carefully designed. Steel elements are used to pass on the substantial forces and realign them along the grain of the wooden columns.
Detail of the connection between core columns and foundation, which are also crucial points in the construction. As a connection to the concrete and also to provide extra stiffness, again steel elements are used.
Detail of the connection between the roof beams of both directions. Steel rods penetrate the entire height of both beams and are tightened to allow forces of the column and upper or lower beam to be transferred.
A dynamic shading system is provided on the facade to prevent overheating.
The facade is designed in a way that makes sure water infiltration is avoided and also provides the possibility of natural ventilation caused by a stack effect.
The design provides an open and adaptable plan.
Underneath the floors, ventilation and cooling is provided through a network of 'veins'.

The structural concept creates an enhanced view towards the outside, opening up the levels to the sides.

TT The Tree
The design intention is to make a tree-shaped building out of wood, which functions as a library. We studied the structure, climate and fire safety to create a feasible design.
