HousePlans.com and the websites of Western Home Builders and Pacific Modern Homes provide several floor plans for small backyard guest houses that are free to view. Each website also features pictures of houses and descriptions of the plans.
HousePlans.com features a collection of detached garages, garages with workshops, living spaces and backyard cottages, all of which can be used as guest houses. These buildings each encompass fewer than 1,000 square feet. Each entry features pictures or artists' representations of the homes and descriptions of the number of bedrooms and bathrooms, the square footage, the number of stories and the price. In addition to free floor plans, users can purchase multi-copy, reproducible, PDF and computer-aided design sets. Some of the plans also come with customization options, and users can call House Plans to get a free modification quote.
Western Home Builders has a few backyard houses that include floor plans and elevation. Select houses also have photos. The PDF floor plans require Adobe Acrobat Reader to view. Pacific Modern Homes includes a number of plans for cabins and granny flats that can also be used for guest quarters. The website also offers free plan review sets, home plan costs, building kit costs, artistic depictions of homes and construction cost estimates.
