Windsor House

Windsor House is a villa, dating from approximately 1839 to 1850, and subsequently altered, now used as offices. It is built of painted stucco with a hipped slate roof. The two-storey main block has a basement and attic, with five first-floor windows, the outer bays projecting forward. The facade features a plinth, surmounted by two-storey Doric pilasters between the windows and clasping the angles. There is a frieze, architrave, cornice, and a blocking course. A central flight of roll-edged steps leads to a tetra-style, pedimented Doric porch with triglyphs and metopes to the frieze on its sides; within the porch are double-panelled doors and an overlight. Windows are mostly 1/1 sashes in plain reveals with sills, those to the first floor sitting on feet. The attic windows are casements. The returns have a five-window range, with similar Doric pilasters to the end bays; the first bays are blind, and the remaining windows are 1/1 and 2/2 sashes. The walls ramp down to the end of the right return.

The interior includes embellished cornices and an open-well staircase with rod and bobbin balusters, some of which have been renewed.

The Bayshill estate was developed by a joint stock company, which acquired land from the Skillicorne family in 1837. In 1843, Henry Davies' guide to Cheltenham described numerous detached villas occupied by affluent residents. The company became bankrupt by approximately 1845, and Onley purchased much of the Bayshill property, leading Verey to suggest that other houses may have been built to his designs. Little described Windsor House as part of a “superb group” of villas that make Bayshill Road one of England’s most architecturally significant roads.
