Chestnut Hill interior designer Mona Ross Berman insists, rather modestly, that there’s no such thing as a “signature” Mona Ross Berman design. But the preppy modern style of Charlie and Cynthia Szoradi’s Wayne home begs to differ. After Charlie, a green architect and founder of Greenandsave.com, pulled off an eco-conscious doubling of the house’s size, Cynthia, a decor-savvy realtor, asked Mona to blend the old with the new. The result is a seamless and chic interplay of pattern and color, heirloom and contemporary, classic and kid-friendly, elegant and artistic (thanks to many original works by Charlie and son Calvin). In the end, the house was perfect for the young family—which, in itself, is signature Mona Ross Berman.
