Garden views on this tiered and wooded one-acre property, as well as year-round sunsets, are part of the sunroom of this midcentury expanded ranch. In fact, the homeowners say the indoor-outdoor versatility makes the sunroom one of their favorite spots in the house.

Accessible from both the living room and kitchen, it has four sets of sliding glass doors, which when left open, are substituted by built-in sliding screen doors.
