105 And 105B, Gloucester Street

105 and 105B Gloucester Street is a house dated 1695, constructed from coursed squared limestone with areas of old limewash and a stone slate roof. The right-end stack has been rebuilt in brick. The building features two gables on the front and consists of two storeys and an attic, with a three-window range.

On the first floor, there are three 6/6-pane sash windows in stone surrounds that have been enlarged, with ovolo-moulded stone mullions and transoms cut out. Above the gables, there are two 2-light ovolo-moulded stone mullion and transom windows with leaded lights; the window on the left was inserted in a former hoist opening and is dated 1984. The ground floor has two 6/6-pane horned sash windows in surrounds similar to those on the first floor. To the left, there is a plank door in a moulded stone doorcase, flanked by pilaster strips and featuring recessed panels with gothic traceried heads and carved scrolls above, supporting a coved stone cornice. An oval plaque in relief at the centre displays the incised initials BBI and the date 1695. Moulded strings run over the ground and first floors and above the windows in the gables.

Inside, there is a late 17th-century closed string dog-leg staircase with heavy turned balusters and square newels leading from the ground to the second floors. The ground floor front and first floor rear have late 18th-century stone chimneypieces. The first floor front features a late 17th-century bolection-moulded timber chimneypiece with a floating cornice and a raised and fielded overmantel panel, flanked by pilasters and topped with a section of moulded timber cornice. There is a mid-18th-century hob grate, and a built-in cupboard to the left has a pair of doors with raised and fielded panels and a matching cornice. A large late 17th-century bolection-moulded timber chimneypiece with a pulvinated frieze, comparable to that at No. 9 Park Street, is currently stored in the entrance passage to be reinstated in the ground floor rear. Parts of the late 17th-century roof structure, including one clasped purlin, are visible on the second floor. The interior has undergone 20th-century alterations, especially in the rear wing, and the interior of the flat (No. 105B) has not been inspected.
