Ulmerton Road (SR 688) runs nearly 13 miles across the middle of Pinellas County, and now a century-old boathouse built by the busy highway's namesake is on the market in Indian Rocks Beach.
The boathouse, which is located at 81 Gulf Blvd., was built between 1911 and 1912 by successful Largo citrus grower Harry Ulmer on property owned by Pinellas pioneer Horace H. Hamlin.
At the time, the interior of the boathouse featured a wooden catwalk and three boat wells, and was home to Ulmer's personal yacht "Miss Largo." On the second level, there was one bedroom and an open porch.
The structure was also rumored to be used by rum runners during prohibition, though there's no records to actually prove it. "That's what we heard, but we know nothing about that," said previous owner Billy Bie to the Tampa Bay Times in 2017.
Bie's father, local businessman and realtor Norman Bie, purchased the property for $300 in 1938, and turned the boathouse into a functional home for his wife and six kids, according to the publication.
Within the first few years, Bie closed off the boat wells, and put flooring down on the first floor, which added space for a realtor's office and a bedroom. He also partitioned off the second story for a dining room and a living room, and later added a third story sleeping area and bathroom.
The boathouse stayed in the Bie family until it was sold in 2023 for $1.5 million, according to property records.
Today, the 3,330-square-foot residence is split into two units, and comes with a total of five bedrooms, three bathrooms, two kitchens, and two exterior covered patios facing the intracoastal.
The boat is currently asking $2,999,900, and the listing agent is ToniLisa Phillips of ToniLisa & Co.
