Here’s what we know so far about the school-to-condo conversion happening at 34 Prince Street, now known as “The Residences at Prince”: The former St. Patrick’s Old Cathedral School will be transformed into nine luxury homes (seven condos and two townhouses, designed by Marvel Architects), all of which will be “unique” and pricey (duh). Exterior renderings have already made the rounds, but the interiors have been a mystery; and while we still don’t know what those condos are going to look like, these renderings show the inside for one of the development’s townhouses, which will hit the market today for $25 million. The five-story home, which sits on the Prince Street side of the block-long project, is as over-the-top as previous reports have suggested: It’ll span 10,000 square feet, with two gardens (in the front and back), three working fireplaces, and even an elevator. The floor plans below show the layout of the massive house, which has seven bedrooms, seven bathrooms, an ornate staircase, a study, and a more then 1,000 square foot cellar.
