Art gallery draft poche drawings

The poche diagram below demonstrates the light which enters through the entrance, exit, stairwell and the main gallery wall from the low ground height windows. Light is diffused from the lower windows and this protects the art.

In section, the most light enters through the roof skylights and down through the stairwell. Light also enters through the glass shopfront window facing the street. The gallery is protected from direct sunlight by low windows in order to not damage the artworks.
