He built a madrasa, mosque and sufi convent on the left side of Shari Saliba in what is today the Old Islamic District of Cairo in about 1440 AD, which is a fine example of how urban monuments in the late Mamluk period were often smaller and more compact due to the dwindling space available for construction. While all seems normal from the street level, by climbing the square based minaret, which is original though its pencil shaped top with a star pattern carved in stone is an awkward later addition, one may look down upon the complex to see how ingeniously the various parts have been tucked behind the facades so that the various demands of this cruciform building could be met. It is the first example of a religious structure in which the interior forms a wide angle with the street facade.

The building had to include a qibla orientation, a position on the qibla wall and the main street for the mausoleum. There are symmetrically disposed windows and doors for the attached foundations and as far as possible, it has a symmetrical internal arrangement. 

This mosque has two facades, with the main one on Sharia Saliba. With a balance and unity that is very pleasing, the entrance portal in the middle of the facade is elaborately decorated with ablaq and reversed trilobed forms of black and white marble. It has accents of colored stone in a style that is characteristic of the late Mamluk era. 

To the left of the entrance is the sabil-kuttab, together with the minaret, and to its right, the facade of the tomb surmounted by a carved stone dome with the earliest example of interlocking ribs made from high-relief moldings.  The kuttab eaves have a cut out pattern that mimic the stalactite pattern of the tomb cornice, while the patter of the lintel over the kuttab door echo that of the windows in the tomb facade. 

The second, or eastern facade is on the side of the street. Here, a round window in the style of a bull's eye is situated in the center of a panel over the mihrab. 

The entrance corridor winds around the tomb and connects with the mosque and madrasa interior. Within, the window to the right of the mihrab is much deeper than the one on the left. The northeast liwan (iwan) provides an entrance to the ablutions court. The southwest liwan is roped off for women, and there is an interestingly shaped closet for storage. 

Due to the configuration of the building to the available space, small cubes of space in corners and angles which result from these adjustments and compromises are often used either as light and air shafts or are filled in as solid masses.
