A one-of-a-kind Oak Forest home doubles up on many of its features. Two chimneys form a sassy kind of turret above the front porch. There’s a second formal entry. And both wings of the home have their own garage. Plus, the property occupies an oversized corner lot, so it’s got twice (or maybe even thrice) the yard of its neighbors. The 13-year-old custom home appeared on the market last weekend. Its asking price: $925,000.
