The $26 million renovation included new state-of-the-art heat and air conditioning systems along with a new electrical service, fire protection and plumbing systems. The property is now fully accessible to people with all abilities.
“This historic building in the heart of Harvard Square has been meticulously restored to preserve its architectural beauty and significance,” said Jameson Brown, Chairman and CEO of The Hamilton Company. “At the same time, we have created an all-new living experience for Longfellow Apartments residents that features high-quality finishes in every unit and excellent amenities.”
