37, 41, and 45 Old Street are houses that have been converted into shops and dwellings, dating from the 18th century. They are constructed of roughcast brick and brick, with old plain tiles on the roof and a brick end stack on the right side. The buildings are three storeys high with a cellar and feature a six-window range. The first and second floors have 6/6 sash windows set in broad moulded cases under segmental arches, with a storey band between the floors. The eaves are decorated with brick modillion.

On the left side, there is a square-headed passage leading to the rear. A 20th-century half-glazed door is set in a 19th-century moulded case, which has a moulded flat hood supported by corbelled consoles and plain pilasters. There is a late 19th-century shop window with a fascia board between consoles on plain pilasters, featuring plate glass. A 20th-century door and frame for No. 45 are also in a 19th-century case with a moulded flat hood on consoles and plain pilasters. To the right, there is a 6/6 sash window in a moulded, round-headed case under a segmental arch.

The right side of the building is faced in 19th-century brick. The rear is made of rubble and brick, featuring two 19th-century casements on the second floor, and a 20th-century horizontal casement in an altered opening on the first floor. The gable of the two-storey wing at the rear of No. 45 has a massive principal rafter with a trenched purlin. The rear of No. 45 also shows some timber framing with brick infill. There are two- and three-storey wings at the rear, constructed of brick with plain tiles and slates, and a brick stack.
