Squeezed snugly between a towering Burger King to its left and a Wendy's to its right, 551 Boylston (also home to a psychic office and a dental association) is one of several holdings owned and managed by Bostonian Properties. The company's stated aim is to combine "creative thinking" with "market knowledge" to develop truly unique properties in and around Boston. The flagship property is 45 Grovers Avenue, a complex of federal-style waterfront condominiums. Though the company develops real estate primarily in Boston, the main offices are located in Winchester, Mass.
