Joseph Broadbent, clerk of works, owned the two houses until his death in 1879. During this time he made considerable alterations to both of them. In 1861 Number 69 appeared as a four roomed house, the following year it increased to five rooms and increased again in 1874 to nine rooms. In the same year Number 71 had one room added to become six rooms. In 1880 the houses became the property of his daughter, Ann Atchison and her husband,James Dale Atchison, as his wife, Elizabeth had pre-deceased him. He kept Number 69 at nine rooms but added a seventh room to Number 71 in 1888.
