Marriott International has signed an agreement with developer BPM Real Estate Group to bring its Ritz-Carlton brand to Portland and the Pacific north-west.

Under the contract, the brand would manage 251 hotel rooms and 138 residential units – including eight spacious penthouses – within a nearly $600 million, 35-story tower that would have sweeping views of the city’s majestic landscape.

Construction is expected to commence later this year, with an anticipated opening in early 2023.

“This landmark project is a game changer for the Ritz-Carlton brand and the city of Portland,” said Noah Silverman, Marriott International, chief development officer, North America full-service hotels.

“The Ritz-Carlton, Portland will set a new standard for luxury hospitality in Portland, expand this iconic brand to the Pacific Northwest and introduce locals to the refined elegance and amenities associated with the Ritz-Carlton Residence lifestyle.”

The hotel and residences would rise within BPM’s planned mixed-use tower, which would also feature high-end office space, retail space and a ground-level food hall.

The site is a few blocks from Pioneer Courthouse Square, the most-visited tourist destination in Oregon, and the shopping destination Pioneer Place.

It is also within walking distance to Portland’s central business district and the Pearl District, the former warehouse district now known for its chic restaurants and bars, galleries and boutiques.

“We are excited to work with Marriott International to deliver an unprecedented level of service and accommodations to Portland’s residents and visitors,” said Walter Bowen, chief executive of BPM Real Estate Group.

“Working hand in hand with the Ritz-Carlton team, we aim to create the best address to live and stay not only in Portland, but the Pacific Northwest.”

Once open, the Ritz-Carlton, Portland will feature exclusive entrances for hotel guests and residence owners, along with high-end amenities including a fitness centre, full-service spa and swimming pool on the 19th floor. “

The Ritz-Carlton Residences are expected to provide luxury living at a level not yet seen in Portland, complete with sophisticated style, luxurious finishes and legendary Ritz-Carlton service, including room service and housekeeping.
