Portwalk Place | Portsmouth, NH

The Challenge

Develop a five ­acre, 400,000 square foot location into a mixed use development located in downtown Portsmouth, New Hampshire that would help transform and reconnect the city’s North End.

The Process

Portwalk Place represented a strong public/private collaboration and master planning to ‘heal and reconnect’ the downtown fabric. 

To create better access to the North End and infuse the area with energy and walkability, Cathartes created a large pedestrian loop connecting three major city streets with the Vaughan Mall walkway and built the largest underground parking facility in the city. The development of Portwalk residences now provide modern living in the heart of the city where none was previously available, while pedestrian friendly streets and hotels have added new restaurants, office space and increased tourism.

The Transformation

The transformation was completed in three phases:


In 2010, the Marriott Residence Inn opened, followed by a Opus, a 36­-unit apartment building in 2011, including ground ­level retail shops and the British Beer Company restaurant.


Completion of a 113­-unit apartment building called Aria, the Hampton Inn and Suites, above and below ground parking garage and 20,000 square feet of retail and commercial space, including the Row 34 restaurant.

The Results

The final development includes 379 hospitality rooms located in three separate hotels, 149 luxury apartments, 50,000 square feet of active street­ level retail and restaurant space, and 300 parking spaces.
