cornice. The siding and trim are unusually ornate and varied. A continuous band of vertical siding at the base of the structure is capped with a horizontal band at the window sill. Drop siding occurs up to the sills of the second story windows, above which multiple rows of fish-scale and rectangular shingles alternate. Ornamental bargeboard trim with brackets is located at the eave line, and the roof is wood shingle. Two brick chimneys rise far above the cedar shake roof. A dormer on the west elevation has diagonal support brackets for the overhang and crossed bargeboard trim. There are 22 double hung windows. Interior floor plan The first floor interior of the house is composed of five rooms. From the front door one enters the main entry hall, which contains the stairway balustrade that leads to the second floor. From the foyer one can enter the main parlor via a door on the right. The parlor contains a fireplace (and functional chimney) with a mantle and brightly colored tiles arranged in a complex non-repeating geometrical pattern. A pair of very large wooden double-doors (that slide into pockets) separate the first parlor from the second parlor. The second parlor has one door which leads to a wrap-around exterior covered porch and another door that leads to a formal dining room. The dining room is completely lined with tongue and groove beaded boards (ceiling and walls) with wainscoting that wraps around all four walls. The dining room then leads to a small kitchen. The kitchen has a door that opens to the wrap-around exterior covered porch. The staircase in the main entry hall leads upstairs to the second floor, which is composed of three bedrooms, a small closet, a small bathroom, and a large hallway with a balustrade surrounding the stairwell. From the hallway, a large window opens onto a small exterior balcony. History Robertson Hill Joseph William Robertson (1809–1870) is the patriarch of the family after whom Robertson Hill was named. Robertson was a physician, a Texas Ranger, and a member of the House of Representatives in the Fourth Congress of the Republic of Texas. He established a pharmaceutical business and a medical practice on Congress Avenue. He was elected mayor of Austin in 1843. Robertson is buried in Oakwood Cemetery, two blocks from the Southgate–Lewis House. In 1848, Robertson purchased a large tract of land from Dubois de Saligny
