Landscaping or special setting features: Jefferson Place Subdivision is a historic residential neighborhood adjacent to downtown Louisville. The subdivision is laid out on a standard urban grid of narrow, deep lots with rear alleys. Houses are built to a fairly consistent setback line along the streets with small front lawns, deep rear yards and mature landscaping. Small, carefully maintained single-family residences predominate. Most of the houses are wood framed, one or one and one-half stories in height, featuring white or light-colored horizontal wood or steel siding, gabled or hipped asphalt shingled roofs and front porches. While many of the houses have been modified over the years, most of the historic character -defining features have been preserved. 800 Jefferson Avenue was built in the 1950s, long after most of Jefferson Place was constructed. Its architectural style is much more contemporary than its neighbors. This commercial building is on a large 3-lot corner property. The building's use, size, and height are unusual in Jefferson Place. Although its address is on Jefferson Avenue, it has frontage on Spruce Street, which historically contained the subdivision's commercial and public uses. A commercial property in this location is consistent with the original design intent of Jefferson Place. The building is set well back from both streets, with unfenced lawns on all four sides. Landscaping is minimal but well -tended. There are juniper shrubs on the southwest corner. Along the northern end of the west facade, there are patios covered with a wooden pergola and enclosed with wooden fencing and raised planter beds. A gravel driveway along the north side of the property leads to a parking area at the northeast corner. 24. Associated buildings, features, or objects: None. IV. ARCHITECTURAL HISTORY 25.
