Sunnyslope Lodge

Why it's listed
Sunnyslope Lodge is a modest one-story cottage on Robinson Mews in San Diego's Hillcrest district, set flush with the street on a narrow canyon ledge overlooking Albatross Canyon. Built between about 1902 and 1906 and designed by Irving J. Gill, it has stucco walls, a flat roof, a round-arched loggia and a small square water tower with arched openings. A rear bedroom and sitting room were added before 1918, matching the original details. Inside, Gill tested thin walls made of 1x4 studs with lath and plaster, smooth slab doors and flush baseboards, along with handmade brick floors. Cobblestone terraces and retaining walls survive beneath a 1930s redwood deck. The house was one of twelve low-cost experimental cottages Gill built between 1900 and 1908 for workingmen's families, and it reflects his interest in clean, affordable housing. It remains a private residence, with a studio and potting shed on the lot.
Significance in brief: The nomination argues it is significant at the state level under Criterion C in architecture as one of twelve experimental low-cost cottages Irving Gill built between 1900 and 1908. Here Gill developed flush detailing, slab doors and thin-wall construction for affordable working-class housing. It was his first venture in housing for working men and previews the simple massing and arched arcades of his later work.
