We went through several local GC’s that wouldn’t give us the time of day. Shannon was immediately responsive and never stopped being so throughout the project. The usual ups and downs with any home reno were always met with “we’ll take care of it.” I have nothing but high regard for Shannon and his crew and subs. I strongly recommend you give them a shout if you want a GC that still takes pride in their work.
Working with The O’Brien Group was an amazing experience from start to finish. The team was professional, attentive, and truly cared about bringing our vision to life. They kept us informed throughout the renovation process, stayed on schedule, and delivered exceptional craftsmanship. We’re thrilled with the final result and would gladly recommend them to anyone planning a home renovation.

Frequently Asked Questions About Home Remodeling & Renovation Dallas!
Will a home addition require a new foundation?
Yes. Most “build-out” additions require a new concrete slab or pier-and-beam foundation. Our team handles the engineering and city inspections to ensure your new space is rock-solid.
Do I need to move out during a major addition?
For many ground-level additions, you can remain in your home. For second-story additions, we may recommend a short stay elsewhere for safety and comfort, which we will discuss during the planning phase.
How do you handle Dallas zoning and permit requirements?
We manage the entire process. From checking lot lines and setbacks to securing permits from the City of Dallas, we ensure your project is fully compliant and legally documented.
What is the typical ROI for adding a room in Dallas?
Adding square footage, specifically bedrooms and bathrooms, consistently provides one of the highest returns on investment in the Dallas market, especially in areas like East Dallas and the Park Cities.
