Rentals of 30 days or longer are permitted, and a turnkey furniture package is available. A rare landmark home and proven income property in one of Grand Rapids' fastest growing area! Some homes have a story. This one has a legend. Before it was the most distinctive residence at Union Square, Unit 224 was the boys' gymnasium of Union High School — the 1870s landmark that educated Grand Rapids' west side for nearly a century. When Pioneer Construction converted the school into 180 condominiums, one unit inherited the gym's crown jewel: a 24-foot floor-to-ceiling wall of glass that fills three stories with light and frames the downtown skyline. No other home in the building has it. No other home in West Michigan has anything like it. One home, one owner, twenty years of care. This unit has been held by its original owners since the building's 2006 conversion — and unlike most "meticulously maintained" claims, this one comes with receipts! A private garage plus assigned gated parking — in a neighborhood where parking is fast becoming the scarcest amenity of all. Building amenities: rooftop pool and hot tub with skyline views, fitness center, and clubhouse. The location is a 2027 headline you can buy in 2026. The $175M, 8,500-seat Amway Stadium — home of AC Grand Rapids — is rising just four blocks away, opening March 2027. And two blocks over is Bridge Street, the west side's superstar corridor: New Holland's The Knickerbocker, Bridge Street Market, Long Road Distillers, Butcher's Union, Gin Gin's, and Bridge St Bar, with new openings arriving yearly. Downtown, the Medical Mile hospitals, GVSU's Pew Campus, and the new Acrisure Amphitheater are minutes beyond. Walk to a match, a tasting, a market run, or a show — and walk home to the gym. Rentals of 30 days or more are permitted, the established Airbnb listing conveys with the turnkey furnished package, and the next owner can be welcoming a monthly resident within weeks of closing. Live in the landmark, or let the landmark work for you.
