The deal would see 64,000 residents accommodated in new houses built over the next eight to ten years at a site to the north of Kabul, Gholam Hassanzada, chief executive of the government's development authority, told AFP.
"We will sign a contract with IHFD in the next two to three weeks," Hassanzada told AFP, referring to the Colorado-based company International Home Finance and Development.
Under the deal, IHFD will seek to raise USD 1.2 billion of funding to complete the project, he said.
The start of construction work will be marked later this month with a ceremony at the site between Kabul and the Bagram military airbase.
Kabul city remains badly scarred by decades of war with many houses in ruins and main roads covered in pot-holes despite 11 years of international aid since the extremist Taliban regime was ousted in 2001.
