It was relocated back to Campbell and now operates as a house museum.","why_significant":"The nomination argues the house and garage are exceptional examples of English Tudor Revival architecture within the California Arts and Crafts movement of the 1920s. It is attributed to designer-builder Addison M. Whiteside. The house also symbolizes Ainsley's success as a fruit canning pioneer and Campbell's 1920s prosperity.","narrative":"Built in 1925 for fruit canner John Colpitts Ainsley, this wood-frame house at 300 Grant Street in Campbell, California, draws on the Tudor cottages of rural England. Its false-thatched roof of rolled shingles, textured stucco walls, half-timbered sections, leaded-glass casement windows and brick chimneys give it a picturesque, handcrafted look, while low proportions reflect California Arts and Crafts design. A matching three-car garage stands beside it. The design is attributed to local designer-builder Addison M. Whiteside, whose firm built many houses around San José. Ainsley, born in Yorkshire, England, became a pioneer fruit canner and one of Campbell's largest employers. The house was moved away and later returned to Campbell, where the city restored it to its 1926 appearance with original furnishings. It now operates as a museum in the downtown civic center, and the garage houses a gift shop and gallery. It was listed for its architecture.","period_of_significance":"1925","architect_builder":"Addison M.
