It was more intrigue than love at first sight. When the British interior designer and antiques dealer Rose Uniacke initially visited the home where she now lives, on Warwick Square in London’s Pimlico, she was struck by its singular qualities but ultimately was content to walk away.

“It was too large, too damaged, and most definitely too big a project,” she writes in her new book, Rose Uniacke at Home, which is dedicated to her Warwick Square undertaking and will be released by Rizzoli on October 26. Years would pass between the first time she and her husband, film producer David Heyman, toured the 19th-century property—a brick Victorian, quite unusual for the area—and their ultimate decision to purchase it, in 2007.
