A Cinder Block Duplex in Charleston Is Recast as a New York–Style Loft

When architect Kevan Hoertdoerfer was asked to turn "probably the ugliest house in Charleston" into the proverbial swan, he was both thrilled and apprehensive. "It’s a dream to have a client who gives you an open book," he says of the instruction to do anything he wanted. "On the other hand, you’re compelled to do something really powerful." The resulting metamorphosis of a squat 1950s cinder block duplex into a concrete and glass neighborhood standout leaves no trace of its ugly duckling origins.
