The central hall is flanked on either side by the chambers originally for the Senate (Yaheg Mawos sena Meker-beth) and the Chamber of Deputies (Yaheg Mamria Meker-beth).

Originally the main facade had a large mosaic of St. George and the Dragon (Ethiopia's Patron Saint) in its centre, flanked by the two Lions of Judah on either side.

After the end of the monarchy the mosaics were painted over, and the gilding that covered the winged lions on the gates has worn away.

The design of the building is centered upon three drum-like shapes, symbolising Negarit drums, which were sounded upon the promulgation of imperial decrees.

Since the site is sloped, below the drums will sit offices for MPs and their staff.
