Number 30 Including Area Railings And Wall

House, now factory, at number 30 St Andrew Street, Hertford.

The building dates from the early 18th century but was refronted in the early to mid 19th century. The interior of the ground floor was remodelled in the early 20th century to form a factory workshop. The structure is built of yellow stock brick in Flemish bond on the front, with a steeply pitched old tile roof behind a parapet. The plan is double-depth, possibly originally double pile, arranged in 4 bays with a side entrance.

The exterior consists of 2 storeys with attics. The first floor features 4 recessed sash windows with 16 panes each, set under rubbed brick flat arches, with a stone band at sill level and stone parapet coping. The ground floor has 4 similar windows. The flank elevation to the east displays 3 cast-iron bell pattern rainwater heads at parapet level. The right-hand rear elevation to the north-east retains a single flush-set sash window with an architrave surround beneath a red brick rubbed flat arch. The roof has 3 box sash dormers and brick chimneystacks at the left and right. The east elevation is constructed of dark red brick on the first floor above a cement-rendered ground floor, with part of the rear in red brick on the first floor. Extensive single-storey factory buildings of early to mid 20th-century date abut the rear wall.

The interior has been much altered, particularly on the ground floor, which has been opened out to form a single workroom. Fragments of 18th and 19th-century panelling and cornices remain around the perimeter walls, and the principal chimneybreasts of the front rooms survive against the outer walls. Around the right-hand wall and chimneybreast, and along the front wall to the middle of the second window from the left, early to mid 19th-century panelled dado, plaster scotia, and reed cornice are present. To the left of this point is a mid-18th-century deep double cyma entablature wood cornice with panelled walls and a panelled upper chimneybreast, though the fireplace has been blocked and the surround removed. To the right of the fireplace is a way through to number 32. To the right again, the cornice to the rear left ground floor room picks up the reeded pattern across its chimneybreast. In the rear right corner a staircase has been partitioned off.

The staircase is recessed from the east wall. The lowest flight rises along the rear wall and turns at right angles to the first floor above a quarter landing. It features open string construction with nosed treads and carved brackets, a curtail tread at the foot, fluted Tuscan column newels, and balusters of irontwist columns on bobbin urns with square section plinth and cap blocks. The handrail is moulded and ramped to the first floor. More elaborate tread brackets and different proportions of balusters indicate that the lowest flight is a 19th-century reworking of the original mid-18th-century dogleg plan open well stair, which rises above the first floor. This upper flight has a panelled dado with baluster and rail details generally as described. The two principal 2-bay front rooms contain some 19th-century features, while the rear rooms retain 18th-century wood cornices. The attics have been much subdivided in the 20th century. The roof was not accessible for inspection.

The front forecourt includes early 19th-century cast-iron railings with square balusters and flattened urn finials. A curved return end at the left connects to the front corner of number 32, with the railings butted to a yellow brick curved boundary wall at the right, set in Portland stone curb. The second bay from the right has a gate, now fixed shut.
