"On a restricted lot only about eighteen metres square, this small house for Abd al-Halim Bey al-Beyli, makes best use of its tight boundaries by deferring to both the northern and western property lines, to allow more open space on the other two sides of the house. Like other buildings of Fathy's early period, it is Modernist in style." (construction not verified)
