A $20 million gut renovation project by Norwalk-based Seligson Properties updated a 68-year-old bank building that includes Stamford Health medical offices and a Wells Fargo Bank branch.

The developer updated the 27,000-square-foot structure at 637 West Ave. in phases, enabling the bank branch and medical group to remain in operations.

Liberty Bank provided financing for the recently-completed project. Other members of the project team included Pustola & Assoc., Long Consulting, Redniss & Mead, Eric Rains Landscape Architecture and architects SLAM Collaborative.

Upgrades to the property included new exteriors, windows and lighting, a new covered entrance and brick facade and updated interiors.

Stamford Health occupies 24,000 square feet of medical offices on four levels, while Wells Fargo operates a 3,000-square-foot retail branch on the ground floor.

“Creating state-of-the-art health care facilities and ensuring a vibrant retail environment for Norwalk’s business community and residents has long been a key strength of our firm, and we’re proud to expand on our growing track record,” Seligson Properties CEO Stanley Seligson said in a statement.

Nuvance Health, Hartford HealthCare, and the American Cancer Society are among Seligson Properties’ medical clients.
