He built a council hall in his portico, which he called the House of Gold. He covered all its walls with gold, inlaid with lapis lazuli in the most beautiful patterns. He made raised figures on its walls of wood, carved in his likeness, and in the likeness of his concubines and singers, who sang to him what he desired. He adorned them with colorful garments and jewelry.

In front of this house, he made a basin filled with mercury. The reason for this was that he complained to his physician of insomnia. The physician advised him to try mercury, and he agreed. He ordered a pool of mercury to be made. The pool was said to be sixty cubits in width and filled with mercury. He placed in the corners of the pool silver pillars, each a cubit long, made of special silver. In the pillars, he placed silk belts in silver rings. He made a mattress of leather, which was filled with air until it inflated, then it was tightened and placed on the pool. The silk belts, which were in silver rings, were attached to the silver pillars, and he would sleep on this mattress. This mattress would constantly sway and move with the movement of the mercury as long as he was on it. No king before Hamarawayh had ever done anything like this.

He also built in the palace a dome that rivaled the dome of the sky, which he called the Dukkah. He often sat in it to overlook everything in his house, the garden and other things, and to see the desert, the Nile, the mountain, and the entire city. He built another field larger than his father's field. He also built in his house a place for lions, where he kept seven lions, each capable of devouring seven men. For each lion and lioness, he made a marble basin. He appointed keepers for these lions who were responsible for their food, drink, and cleaning. Among the keepers of these lions was a blue-eyed lion named Zurayq, who had been brought to Hamarawayh and was set free in the house, harming no one. He was given a daily ration of food. When Hamarawayh's table was set, Zurayq would come and lie down at his feet, picking up the scraps he threw to him. When he slept, Zurayq would come to guard him. If he slept on a bed, he would lie at the foot of the bed, and if he slept on the ground, he would lie beside him, never neglecting him for a moment.

Hamarawayh's stables also expanded. He made a separate stable for each type of animal. He made separate quarters for the leopards, and the same for cheetahs, elephants, and giraffes, all in addition to the stables in Giza. He also had stables in Egypt where mares were bred for racing and for use in the cause of God for raids. The army's salaries in his time amounted to ninety thousand dinars annually. The horse races in their time were like festivals due to the abundance of decorations, the riding of all the soldiers, and the commanders, with their large numbers, in full armor and complete equipment. People would sit to watch the races.
