The Little House on the Trailer specializes in manufacturing accessory buildings made to order. The building spaces are between 120 and 400 square feet and can serve as home offices, art spaces, installed guest houses and extra classroom space. All spaces are heirloom, made-to-order, hand-crafted and portable. Also for sale are floor plans that include a list of building materials, if you are feeling adventurous and would like to create a space of your own.
