This is an approximately 600 sq ft casita that was originally just a square slab office space with concrete flooring. TraVek remodeled the side bathroom, added some pony walls to close off a spot for a bedroom. The pony walls allow more natural light through the bedroom. We also put in a kitchenette, changed the patio doors to a wider one in order to give a larger view of the gorgeous Arizona desert. At the same time, we were able to keep the work space. Now this office serves a dual purpose, and is a great place for guests to have their own space.
