Built in 1910 for William Widgery Thomas, a prominent Portland banker and lawyer, this landmark brick mansion on the corner of West Street and the Western Promenade is one of the finest surviving examples of formal Colonial Revival architecture in New England. For more than sixty years it was carefully stewarded by Maine Medical Center, its original character preserved almost entirely: the soaring ceilings, the elegant woodwork, the wide-plank floors, the generous proportions that simply aren't built anymore.

Now, for the first time in its history, the Thomas House is becoming home to nine exceptional private residences.

West Street Developer, a collaboration between NewHeight Group and Great Falls Construction, has reimagined this 14,000-square-foot mansion with the same care its original owners brought to it. NewHeight Group is the Portland-based developer behind 118 on Munjoy Hill, Luminato, Verdante, and the Winter Street Townhomes. Great Falls Construction, a Maine institution since 1988, brings decades of meticulous craftsmanship to the project as Design Builder. The result is a collection of spacious, light-filled homes ranging from one to three bedrooms, each thoughtfully designed to honor the building's character while offering every modern comfort. High ceilings. Abundant natural light. Hardwood floors and views across the Western Promenade to the water and the White Mountains beyond.

Outside your door: 18 acres of one of Portland's most beloved parks, the Western Promenade, directly across the street. A walk score of 83. A bike score of 96. World-class restaurants, Maine Medical Center, and the Arts District all within easy reach. And on-site: private off-street parking, shared outdoor space, a light-filled conservatory, and for select units, private entrances and garden space.
