Sherwood Forest is a hidden enclave of elegant one-story ranch houses on sprawling lots with deep setbacks. Four bedroom, three bath, 1950’s Connecticut. The kind of house Mr. Sheldrake took the 6:15 train home to in Billy Wilder’s The Apartment. If you had the money to buy one, tear it down, and replace it with something twice as big, would you build this? Would you go full New Yerevan Brutalist? Would you pave over the front yard and add the tallest fence in the neighborhood?
