In her work The Voice of the Oud, Jehan Rejab includes some photographs and information on the Bayt Al Ghanim House. She writes that it was built around 1915 by Sheikh Khaza’al and notes how the building was unique in some of its features. Today the building is in ruins, but is protected by a gate (that features these same photos seen in Voice of the Oud) so may be renovated! It is located across the street from the ruins of the Sheikh Khazal Palace.
These photographs of Bait al Ghanim come from the instagram of Ali al Rais.
The following information comes from the article Socio-Spatial Analysis of Traditional Kuwaiti Houses by Omar Khattab, although may refer to a different home as the info differs from that stated in Voice of the Oud.
