The term McMansion did not exist in design vocabulary in 1977 when Myra and Paul Steinberg decided to build a home on Siesta Key in the Roberts Bay Lane neighborhood. And even if it did, that’s not the kind of house they had in mind for their half-acre surrounded by water, sand, mangroves and cedars. The custom house is made of wood (a lot of wood) in a simple ranch style with a boardwalk extending from the front of the house and many windows to embrace natural light and bring the outside to the inside. With three bedrooms and two baths, the 2,000-square foot home was the Steinberg family paradise for 44 years.
