Projects / Multifamily      Portland, Maine

5 India


India Street was established in 1680 as one of the first streets in Portland. From 1903 to 1966, Grand Trunk Station sat at its terminus, where the Grand Trunk rail line brought passengers and goods from Montreal to Maine’s ice-free seaports. As passenger rail-service declined, most of the Grand Trunk infrastructure was razed in 1966. The office building at the junction of India and Commercial Street was left standing to continue housing the Grand Trunk offices until the mid-1980’s, when it too was eventually abandoned. The building is now home to Gorham Savings Bank, who used historic tax credits to restore the structure to its former stateliness.

On the adjacent site, which lay fallow for decades, we had the privilege of designing a new multi-family residential building as part of the city’s redevelopment plan.


5 India Street introduces 24 units of high-performance housing to a historic waterfront site.
