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.

FAQs for addition to existing structure building service projects in Round Rock, TX

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. 

Yes, you can build an in-law suite in your backyard if you meet local building codes and zoning regulations. An in-law suite often occupies 300 to 800 square feet. Be sure to follow size restrictions, utility separations, and entrance requirements. Hiring a qualified contractor ensures you meet all regulatory requirements because they can pull permits, double-check local code, and gather other skilled pros to work on your suite. 

An in-law suite is a self-contained living space attached to—or detached from—your main home. Expect a bedroom, full bath, and a kitchenette or compact living area. The setup gives relatives privacy, doubles as a potential rental, and can lift your property value. To qualify as a legal dwelling, the suite must meet local building codes and zoning rules.
