Rae's Custom Home Services is a one stop shop for all your home renovations and projects. We are known for our ability to achieve your goals, and sometimes we even achieve results others said was not possible or couldn't be done! Our company standards are: Fairness, Integrity, Honesty and Reliability. Communication is something we go above and beyond to ensure customers are just sometimes in the know, but always in the loop from start to finish. Come as a customer, leave as a friend!

"Bryan and his team did a great job with our kitchen remodel! We only wanted to remodel the backsplash and countertops, and they did not try to upsell us on the cabinets as well. Instead, Bryan worked with us to find the best products for what we wanted to upgrade, provided good pricing, and was flexible with us on last minute changes and negotiation. Most importantly, Bryan and his teams were super speedy and turned around things in a week's time, AND Bryan was extremely communicative throughout the whole process which was hugely helpful as we were out of town while the remodel was happening."

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 Austin, TX

Yes, you can add a bathroom on a concrete slab, but the crew will need to saw-cut the slab, trench in new supply and drain lines, and then patch the concrete without weakening the foundation. Working with an experienced plumber and concrete pro keeps the structure intact and helps the new bathroom pass inspections.

schedule covers planning, permits, framing, rough-ins, finishes, and punch-list items. 

Larger spaces or extensive plumbing and electrical upgrades can stretch the timeline, while a simple powder-room conversion may wrap up faster. Hiring licensed pros helps keep the schedule on track and the work up to code.

The best location depends on how your family uses the space. An upstairs bath keeps nighttime trips close to the bedrooms, while a first-floor powder room is handy for guests and everyday traffic. 

Think about where plumbing lines already run, how much square footage you can spare, and what layout changes fit your budget. A pro can map out the smartest spot and handle any code hurdles.

With the right planning, you can carve out a bathroom in almost any part of the house. A successful addition requires sufficient space, proper ventilation, and access to plumbing and electrical systems. Structural modifications and adherence to building codes are essential. 

This process demands careful planning and the coordination of specialized professionals who ensure that the new space meets all code requirements and functional needs.

Under specific conditions, adding an extra bedroom can boost home value more than adding a bathroom. Home value is driven by overall configuration, market demand, and functional balance. A new bedroom influences the property’s appeal in different ways, while an additional bathroom enhances living convenience. Evaluating the current layout and market trends determines the optimal choice for maximum value.
