21 and 23, Park Lane

21 and 23 Park Lane are two houses dating from the 17th century, which were encased in brick during the 19th century. They were altered and converted in the mid-20th century, featuring replacement doors and windows. The houses are timber-framed and clad in rendered and whitewashed brick, topped with a roof of black-glazed pantiles. There are brick stacks located to the left of center and at the right end.

The exterior consists of two storeys and a dormer attic, with an irregular seven-window range. Number 21 has a half-glazed door to the left of a canted bay window, which is fitted with top-hung casements. The first floor features one 6/6 unhorned sash window and one 8/8 unhorned sash window, both within flush frames. Number 23 has a recessed entrance porch in the center of the ground floor, with an early 20th-century glazed door. To the right, there is a canted bay window with top-hung casements, while to the left of the door, there are two casements and five similar casements on the first floor, all of varying dimensions. The houses have a dentilled eaves cornice and one small gabled dormer to the right of center with a casement.

The interior has not been inspected. The houses are historically associated with Thomas Gardner, who was the historian of Southwold and Dunwich from 1690 to 1769.
