Rosehill Manor

Rosehill Manor is a country house built in 1814 for Richard Oxnam, a banker from Penzance. The house was altered and extended in the early to mid-19th century, with a conservatory added later in the 19th century. It is constructed of granite, faced in granite ashlar on the front and sides, and features a slate hipped roof with paired brackets supporting deeply overhanging eaves, as well as lead rolls on the hips and ridge. The granite ashlar stacks have cornices.

The layout includes principal rooms on either side of a central entrance hall, with a stairwell located behind. Servants' rooms are situated in an L-shaped wing at the rear, which was also built in the early to mid-19th century. The roof of the front range was remodeled around the 1830s to include the overhanging eaves.

The exterior is two storeys high with a cellar. The symmetrical three-bay east front features corner pilasters, with the center bay slightly projecting. The windows are 12-pane sashes set in round-headed recesses, with segmental arches above the ground floor windows framed by moulded architraves. A central semi-circular granite Roman Doric portico is topped with an iron balustrade and includes panelled double doors and sidelights with reticulated glazing bars. The south side has similar detailing, and there is a Victorian conservatory on this side. The rear features rusticated quoins and a granite rubble west wall with later additions, along with a rendered two-storey service wing that is L-shaped in plan.

The interior remains intact, showcasing an entrance hall with a segmental domed ceiling and corner pilasters. The stair hall behind features a geometric staircase with an ornate iron balustrade and a lantern with colonnettes, along with an Ionic screen at the landing. The principal rooms are adorned with marble chimneypieces, moulded ceiling cornices, and plaster ceiling roses. The back staircase has stick balusters and a moulded mahogany handrail that ramps up to column newels. The joinery throughout is intact, including panelled doors, architraves, and chimneypieces, with a 19th-century range located in the cellar.

Rosehill was built by Richard Oxnam, who, along with John Balter and William Carne, founded The Penzance Bank in 1797.
