London-based firm originally established in 1855 by Nathaniel Wood Lavers (1828-1911). The firm changed its name several times with the arrival and departure of each partner. Francis Barraud (1824-1900) became a partner in 1858 and Nathaniel Westlake joined the partnership in 1868, having designed for the firm since 1858. Other artists designing for the firm from the late 1850s included Henry Stacy Marks and John Milner Allen.
After the death of Barraud in 1900 the firm was known as Lavers, Westlake and Co., although Westlake had been the sole proprietor since 1880, and windows were being signed 'Lavers & Westlake' in the 1890s. After 1909 the company became N H J Westlake, London, and closed in the 1920s.
