PORTLAND – Developers are proposing a $100 million project that will include a Westin Hotel and luxury condominiums on the site of the former Jordan’s Meats plant, the development team announced Thursday.

The project will be 450,000 to 500,000 square feet and include 150 to 200 hotel rooms and 60 to 100 condominiums, a banquet facility, a parking garage, an upscale restaurant and retail space.

The privately financed project is being developed by PME I Limited Partnership. The joint venture brings together the Liberty Cos., a South Portland corporation, and The Procaccianti Group, a hotel developer based in Cranston, R.I.

The centerpiece of the development is the Westin Hotel, which would be six stories high and rank among the city’s largest hotels with 150 to 200 rooms. By comparison, the Holiday Inn by the Bay, the state’s largest hotel, has 239 rooms; the Eastland Park Hotel has 202.
