"Adapted from a previous design, the plan for this apartment for Fathy's brother works within a curved exterior glass curtain wall, taking advantage of the view, and uses a projecting baratsi truss roof to shade the glass. As in the Mehrez apartment, extremely efficient use of limited space characterizes the design, which also takes advantage of the exterior roof-top area for outside pergola-covered patios."
