Water Stone is a high-end residential project located in the center of Beijing. The assignment asked for a 400m2 so-called sales center; an exhibition-like pavilion in which the apartments will be sold before they are actually built. The building has to accommodate extreme private activities like closing financial agreements and signing contracts while at the same time it has to seduce the public to enter. The building aims to express this ambiguous tension of simultaneously being public and private.

A standard rectangular building envelop is reshaped into an envelop that has three straight and two inclined faces. The reshaping creates a volume with two strong directions: one side seems to open up towards a street corner while the other side seems to close the building of. To emphasize the tension between public and private, the inclined elevations are executed in transparent glass while the straight walls are executed in a translucent double layered skin. Where the building opens up towards the public completely, a narrow casted view over a 1:100 scale model of the Water Stone is offered.
