The chance to renovate a rotating midcentury house is a rare opportunity to make an already groundbreaking design even more compelling. Georgia-based firm Mack Scogin Merrill Elam Architects accepted the challenge when they got the call to update the Round House, a home designed in 1968 by forward-thinking architect Richard Foster for him and his family on a four-acre hillside property in Wilton, Connecticut.

Though the house may be likened to the world-famous Chemosphere designed by John Lautner, the Round House has the distinguishing feature of containing a large ball bearing ring base that allows its occupants to rotate the home at will. A full rotation can reportedly be performed in as little as 45 minutes.

While the firm went to great lengths to bring the home’s exterior back to its original condition—including the preservation and/or replacement of its wooden shingles, its floor-to-ceiling windows, and the patio’s cobblestone flooring—the updates shine through the home’s interior spaces. The firm’s goal was to bring even more light into the 2,997 square foot floorplate by removing as many partitions as possible, adding to a previous renovation that eliminated the wall between the kitchen and living areas and created an open-plan scheme. This move created space for a larger master suite and a secondary bedroom.
