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.

"I would highly recommend T5T Contracting for your project. We originally contacted Terry at T5T to discuss a detached garage, which eventually turned into the garage, extended patio, screened-in porch and pergola. T5T did a great job of turning our sketches into reality at a fair price. At each step of the way, the crews were skilled, efficient and very respectful of the property. Terry does a great job of communicating throughout the project and we are extremely happy with the results."

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
