To the North of the church, forming one of the boundaries of the churchyard is what is still known as the Priestís House. It is a long, low building now divided into two cottages.
At the West end it has an upper and lower window of Gothic design. It is said to be coeval with the church, and was the original glebe house, and the temporary lodging of the monks who came over from Plympton Priory to perform religious services in the parish. Afterwards it served as the residence of the first incumbents of Brixton.
The house was conveyed with the tithes by the Dean and Canons of Windsor, subject to a charge of £20 per annum to the incumbent, to Mr. Thomas Splatt, who took [possession of it in 1840. This charge was commuted in 1891 for £600, with the consent of the proper authority, and this sum went towards the purchase of a more suitable house called Rose Cottage, which served as a vicarage until 1904.
