June 01, 2018 - Northern New England

Portsmouth, NH PROCON started construction on the first AC Hotel by Marriott located in the state. The 152,000 s/f AC Hotel and Event Center is going up at 299 Vaughan St. The project is a collaboration between developers Cathartes of Boston, and XSS Hotels of Manchester, N.H. PROCON also designed the new upscale hotel that will be adjacent to 3S Artspace in the city’s North End. 

Portsmouth-based Colwen Hotel Management will provide comprehensive management services after the hotel opens. A key part of the deal between Portsmouth and the project developers is Waterfront Park. The companies deeded an almost one-acre waterfront parcel of land to the city as part of their agreement. In a January 2017 issue of, Cathartes principal Jeff Johnston said, “The Waterfront Park and Greenway reconnects the North Mill Pond to the North End and offers a wonderful environment to the public for recreation along its pathways, boat launch and scenic vistas. It’s a unique opportunity for the city.” 

The 5-story design features 154 guest rooms in stylish finishes with the AC’s signature wall-mounted workspace and seating bench. The hotel’s décor is modern, high-tech, minimalist and designed to appeal to Millennials and business travelers. Guest amenities will include a fitness center with a dedicated yoga room, a lounge/bar, a library, a 24/7 market and 24-hour business center. An additional 2,360 s/f of first-floor leasable office and retail space will also be available. 

The 4,500 s/f event center was designed for companies to host business events and it subdivides into smaller meeting rooms for private social functions. Plans also include two media salons with collaborative technology and a 1,500 s/f subdivisible conference room on the first floor. Hotel guests will be able to enjoy a rooftop bar and lounge.
