"Cottonwood exceeded our expectations in building our detached garage and apartment. Their attention to detail was evident in every aspect of the project. We were particularly pleased with their ability to accommodate our request for a larger apartment than we previously had requested, giving us ideas for the lay-out and updating the cost quickly for us to make a decision. We also appreciated their advice on maximizing storage space and the design of the garage. The finished product is exactly what we envisioned, and we highly recommend Cottonwood to anyone considering a new garage or addition."

Place Designers, Inc., has been offering professional architectural services in the central Texas area since 2007. We offer free initial consultation, fixed pricing and approachable, accessible service. Few people realize how complicated it is to build, until they find themselves lost in the maze of design options, building codes, zoning laws, contractors, and so on. No two projects are exactly the same, so there is no single, clear cut path. An architect is a qualified professional with the education, training, experience, vision, and license to guide you through the entire design and construction process, from helping you define what you want to build to helping get the most for your construction dollar. Architects look at the big picture. They do not just design four walls and a roof, they create total environments, interiors and exteriors, that satisfy functional needs and are exciting, dynamic spaces in which to work and live.

Building an in-law suite takes between two and seven months. Converting an existing basement, attic, or room can be done in about two months. Constructing a new addition or detached suite often takes four to five months for construction, plus one to two months for permits. The bigger the suite, the longer it will take.
