The design site is located in the main street in Muscat, the capital of Oman. The design proposal for nine floors Al-Khonji complex contains residential and commercial parts. The main challenge in this project is how to make comfortable houses that own privet green yard. After many trials and errors, 5O7studio found out a composition that provides a privet yard for each houses by rotating each floor 90 degree upon the others. This solution inserts various voids into the building’s mass. In addition, we used Islamic patterns as a filter to cut direct view into the houses in order to make HIJAB for each house. In the other hand, the commercial part is located in ground floor that has direct access from the main street and separated from respirational part. This separation enables residents to move in the site without pass through the commercial part.
