We at Texas Select Builders, LLC, specialize in full service design-build remodels and additions with exceptional quality and function. More importantly, after more than 30 years in the luxury residential market, we continue our passion for perfection--providing consistent five star quality, value and customer service on every job we do.

"Jim Johnson is an exceptional builder and honest businessman. You can tell he does this work because he loves it and genuinely wants his work to be the highest quality. He was referred to me by a co-worker with very high standards, and I am so grateful we were able to have his team do our addition and remodel. We have an older home and needed more space, so we added a bedroom above the garage and connected the new space to the existing home. We also remodeled most rooms, including a full kitchen expansion and remodel, new floors throughout, all new electrical wiring, HVAC, interior and exterior paint, plumbing upgrades (and moved a bathroom), and we added a front porch. There were problems along the way, which you'd expect with a project of this size, but Jim did his best to stay within the agreed-upon timeline. Every problem or decision was discussed in a transparent and collaborative way, and his suggestions saved us from future headaches. We now have a solid home that is well-designed and functional. From the big items such as the flow of a new room, down to the motion-detecting lights he suggested for our driveway...no detail is overlooked by Jim, Harvey, and the team. With Jim, you get a builder who is extremely knowledgeable, available, creative, trustworthy, and best of all, he does what he says he will do. It's not easy to find these qualities in a builder."

FAQs for addition to existing structure building service projects in Katy, 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.
