Wright Runstad & Company has secured a master use permit (MUP) decision for the Rainier Square redevelopment project from the Seattle Department of Planning and Development (DPD) in Washington, US.
The mixed-use complex has been planned as a part of the University of Washington’s Metropolitan Tract in downtown Seattle.
Proposed designs for the development and application for MUP was filed by the firm last November.
Wright Runstad & Company president Greg Johnson said: "The master use permit is the culmination of the city’s land use and design review and public comment period."
The 1.15 million square feet project will involve construction of a 58-storey tower, which will offer more than 750,000ft² of office space and house nearly 200 apartment units.
It also includes developments for 30,000ft² of distinctive restaurants and retail shops, along with another 12-storey building that will include a 155-room premium hotel.
A new underground garage has also been planned under the project that will have parking space for more than 1,200 cars.
"The design incorporates feedback from the design review board for a bolder and more dramatic sweeping curve up the east face of the tower," Johnson added.
Architecture firm NBBJ is responsible for the designs of the redevelopment project, construction for which has been scheduled to start in early 2017.
University of Washington is the owner for the Metropolitan Tract where it was located initially. The tract spans across around 11 acres.
First tenants for the tower development under the project are expected to enter the building in late 2018.
