Olivia and Walker Brock looked at dozens of Charleston's iconic one-room-wide Single Houses before they finally found one with their coveted "Three Ps"—porch, privacy, and parking. Unfortunately, the house lacked a fourth "P"—period authenticity. "Over the years, things were added that were too ornate for a small 1780s tenement house," explains Walker. "We took out crown moldings, appliqués—even the hinges." Throughout the renovation, Olivia, who has a master's degree in historic preservation, considered every detail from the shutters to the light switches to make sure they were appropriate for the style and period. By updating the kitchen and adding savvy built-in storage solutions, they ensured the house got a 21st-century refresh while simultaneously returning it to its simple roots. "Restoring an early Charleston Single House was a dream come true for me," Olivia says.
