The house on the left, (7655 Wilmington Dayton Rd) was enlarged and remodeled. The small house in the middle is gone and was replaced by the cul-de-sac Pinebrook Ct. The building on the right is 4400 Pine Brook Ct - a duplex. Property records indicate it wasn't built until 1976, but it's more likely it was remodeled in 1976.
