74-80, Chestnut Grove

74-80 Chestnut Grove is a terrace consisting of two pairs of cottages built between 1909 and 1914 by Parker and Unwin for the Joseph Rowntree Village Trust. The cottages are constructed of brick with a French tile roof. Each cottage features a lobby entry leading to a living room and scullery. The building has two storeys and nine first-floor windows, with a central weatherboarded gable for each pair.

The ground floor includes half-glazed doors and plate glass sash windows, while the first floor has 4-pane sash windows. A central round-arched through passage connects the cottages. Each pair of cottages has two 4-light canted bay windows, with doors beneath round arches that showcase decorative tiling. On the first floor, there is a central flat-topped 2-light half dormer, flanked by single-pane casements positioned slightly lower. Each gable features a pair of 3-light casements, and the outer bays have 2-light windows. The roof is hipped, and the stacks have been removed.

New Earswick is significant for its role in the development of low-cost housing in Britain. The experiences and practices from this area were incorporated into the Tudor Walters Report of 1918, which played a key role in the passing of the Addison Act of 1919. Plans from New Earswick also influenced the Government Manual on low-cost housing that followed the Act.
