After a pandemic-related delay, the residential phase of the massive Rock Row development in Westbrook, Maine is moving forward. Phase 3 of the $600 million project will add 280 residential units, most of them apartments, as well as a 119-room hotel and more commercial and retail space.

Why it matters

The Rock Row development has already transformed a previously empty 110-acre site in Westbrook into Maine's busiest shopping center. The addition of hundreds of new residential units will further establish Rock Row as a major mixed-use hub between Portland and downtown Westbrook.

The details

Phase 3 of the Rock Row development will include 280 residential units, mostly apartments, as well as 13 townhomes for sale. The phase will also feature a 119-room Element by Westin hotel and additional commercial and retail space. Developers are hoping to break ground on Phase 3 next spring and complete it by 2028.

  • Phase 1 of Rock Row brought retailers like Market Basket and Chick-fil-A.
  • Phase 2 added a medical facility with New England Cancer Specialists and the Dempsey Center.
  • Phase 3, the residential component, was delayed by the COVID-19 pandemic.
  • Developers requested approval from the Westbrook Planning Board on April 7, 2026.
  • Developers hope to break ground on Phase 3 next spring and complete it by 2028.
