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."

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

Yes, hidden rooms are legal, as long as they meet all local building regulations. If you sell your house, most states require homeowners to disclose full houseplans, which would include any hidden rooms.

If your secret room is a safe room, it should contain a means of communication aside from a cell phone, such as a shortwave radio. You should also have plenty of drinking water, a portable generator, emergency food supplies, blankets, pillows, flashlights, batteries and a first aid kit.

Any time you update your home’s square footage, you increase its value, but a secret room is a niche feature that doesn't rank high on every buyer’s list of must-haves. Investing your money in remodeling more common living areas like bedrooms, bathrooms, or kitchens will have a higher ROI than adding a secret room. Many secret rooms can act as entertainment spaces (think a game room or wine cellar) or quiet spaces (a library or study), so when building your secret room you may want to consider its versatility for when you’re ready to sell.
