Engineering designs for 100,000 housing units that will cater to Saudi Arabia's middle-income earners have been approved by the Saudi Ministry of Housing, said a report.

The projects, designed by Egyptian property developer Al-Ahly for Real Estate Development, will be located in Dammam and Al-Kharj, said a report in Amwal Al Ghad.

The development company was only tasked with conducting the engineering designs and will not execute construction works or attain new residential projects in Saudi Arabia within this year, the report said.

The 100,000 units, which will also include small villas, are expected to be completed by 2020.
