House Grounds Gardens Great Tree The Laundry 1918 Walker & Gillette had already designed the Hay Barn, Laundry, Carriage House, and Mushroom House on the estate after the Coes had purchased the property from Mrs. James Byrne. This building was located far from Coe Hall to confine billowing steam and drying clothes to the distant working areas of the estate. A brick wall used to surround the drying yard.
