Treeavon, Buckingham House, Montrose, Lorraine, Delamere. Eton House, Railings

A terrace of six houses and attached railings, built between 1823 and 1824. The houses are constructed with stucco over brick, featuring slate roofs, stuccoed end and party-wall stacks, and cast- and wrought-iron area railings and verandahs. Treeavon, a smaller house, is set back and attached to the left end of the terrace in a matching style. The main range follows a symmetrical design, with a double-depth plan including side hallways and two- and three-story service ranges to the rear.

The main range is three stories high, with a basement level and 14 first-floor windows (typically two then three windows per house), the outer houses projecting forward. The house to the left is set further back and has two stories and two first-floor windows. Stucco detailing includes ground-floor rustication on the projecting houses, first- and second-floor bands, a crowning frieze and cornice. The left return has ground-floor rustication topped by a band and Ionic pilasters at the ends and between windows. The recessed house to the left features full-height fluted Ionic pilasters that interrupt the first-floor band, a crowning frieze, cornice, and a blocking course with copings. Six-over-six sash windows are present throughout, with taller windows on the first floor; some basement windows are eight-over-eight sashes, all in plain reveals with sills. Entrances are located on the left return, within a two-story solid porch with Ionic pilasters, and to the right side, with flights of steps leading to six-panel doors with sidelights and fanlights. A conservatory with six-over-six sashes and a hipped roof is situated above the porch on the left return. Rear elevations retain six-over-six and eight-over-eight sashes.

Interior features include original joinery, such as six-panel doors with fluted architraves and cornices with a circle motif at the corners. First-floor verandahs have concentric circle motifs with embellished rods to the balustrade and scrolled motifs to the uprights, with tented roofs. A similar wide balcony is located on the left return. Arrowhead area railings are present, with urn finials to the stanchions and to the sides of the steps.
