Xiaoshan District Master Plan – Metro Line 2 Hangzhou

The project is planimetrically defined by a sole morphological, functional spatial archetype based on the type of ancient courtyard building shared by many populations in different parts of the world.
The courtyard archetype is defined in all its possible variations following a principle which may be defined as the “theme and variations” in music. The system of volumes resulting from the morphological variations have been intersected across their height by a double curved surface which produce the whole final form of the entire project.
The effect is that of an artificial mountain whose slopes have been hollowed out and filled with the buildings. The density calibration of the spaces guarantees the necessary supply of air and light. Nature and artifice co-exist in a single form, which is sinuous in its height and solid and rational at its base. The cover of all buildings, which is entirely clad with photovoltaic panels and does not exceed the permitted height of buildings in the area, rotates towards the sun in order to maximize absorption of the sun’s rays.
The unity that the structure communicates is guaranteed by the exclusive use of a single archetype. The variety of solutions allows a great dimensional flexibility, creating both formal and practical spaces which means it can be adapted to suit almost any requirement.
The choice of this model is the result of the careful evaluation of the interaction between both solid and open spaces. It considers all possible aspects of the distributive and environmental features and requirements of the external surroundings as well as the interior of the buildings. The use of a prototype model allows for modular development on both vertical and horizontal planes which is both economical and easy to construct.
The diverse morphological variations are positioned in such a way as to optimize ventilation and to exploit the natural light penetrating the buildings without interrupting the continuity of the empty spaces.
