Description

This is a house located at No. 49 in Little Gaddesden, dating from the 17th century or earlier. It has been cased in red brick during the 18th or 19th century. The house features a northern gable chimney and a small northeast extension added in the 1870s for Lord Brownlow. A southern wing was added in the 1930s after the estate was sold, and the buttresses on the front wall likely date from this time. The structure is timber-framed, cased in red brick, with a brick southern wing and old red tile roofs.

The house is two stories tall. The older section has two flush three-light Yorkshire sliding casement windows with small panes on each floor, and a two-light window where the central door used to be. There are heavy brick buttresses with two offsets between the openings. A Sun Fire Insurance plaque, number 209530, is displayed on the wall, indicating a policy from June 1764 for Thomas Groome, a carpenter. The large external northern gable chimney features white brick quoins and red brick tumbled offsets, with white brick dressings and decorative vent holes on the northern lean-to extension set back from the center of the chimney. The higher two-story southern wing has a two-story canted bay window to the right of the entrance. The building has a three-bay timber frame with its original roof.
