This 1870s Mansard Victorian underwent a renovation project that spanned more than three decades after the property was condemned due to a faulty furnace. During that time owner Maureen O’Hare Mercer reinvented herself as a consultant on architectural finishes and historical colors and found several opportunities to bring her inspirations to life. This splendid Victorian is located at 173 Oakleigh Road in Newton. It has six bedrooms, three full baths, one partial bath, and more than 4,700 square feet of interior living space. The home is listed at $1,599,000. Listing agent Janet J. Sterman of New England Preferred Properties in Newton is holding an open house Sunday, July 27 from 1:00 p.m. to 3:00 p.m. and a commuter’s open house Monday, July 28 from 6:00 p.m. to 7:30 p.m.
