DFW Home Additions — Primary Suites, Second Stories & Kitchen Expansions
Regent Design Build adds the square footage your family actually needs — primary suites, second stories, kitchen and great-room expansions, and outdoor living additions across Grapevine, Southlake, Fort Worth, Dallas, and the rest of DFW. One team handling feasibility, design, permits, and construction.
Additions that look like they belonged there from day one.
An addition is one of the highest-stakes projects a homeowner can take on — the roofline, foundation, HVAC, electrical, and finishes all have to tie cleanly into the existing house, or it ends up looking and feeling bolted on. We start every addition with a real feasibility walkthrough so you know what's possible on your lot before any design fees, and we handle the architect, structural engineer, city permits, and HOA review under one roof.
Primary suite additions
Add a true primary suite — bedroom, custom bath, walk-in closet, and a private sitting area or office — without compromising the rest of the home's layout.
Kitchen & great-room expansions
Push out the back of the house to open the kitchen to a real great room, add a butler's pantry, or finally fit the island and seating the original floor plan never could.
Family-room & living additions
More living space for growing families — proper sightlines, real storage, and a roofline that looks like it belonged there from the start.
Second-story additions
When the lot won't allow going out, going up is often the answer. We assess foundation and framing first to confirm it's feasible before any design fees.
Home office & flex-room additions
Dedicated, sound-isolated home offices with their own HVAC zone, hardwired networking, and a separate entrance when needed.
Outdoor living additions
Covered patios, outdoor kitchens, screened porches, and pool cabanas that work with your existing roof and drainage — not bolted on as an afterthought.
Our process
How a Regent home addition runs.
No surprises, no handoffs, no chasing five different vendors.
01
Feasibility walkthrough
We walk the lot, check setbacks and easements, look at the foundation and roof, and give you a real go / no-go plus a ROM budget before you sign anything.
02
Design & engineering
Architectural drawings, structural engineering, MEP coordination, and 3D visualization — so you see the finished addition before we break ground.
03
Permits & HOA review
We submit to the city and to the HOA, respond to plan-review comments, and own the timeline so you don't have to chase paperwork.
04
Construction
One superintendent from foundation through finish. Dust containment, protected pathways, and clean job sites — every day.
05
Punch & handoff
Punch walk, manuals, warranty docs, and a clean turnover. Then we stay on call for anything you need after move-back-in.
Who additions are right for.
Most of our addition clients are families who love their neighborhood and school zone and don't want to move — they just need the house to keep up. We also work with homeowners staying in place for the long haul who want a proper primary suite, a real home office, or a kitchen that finally functions the way they cook and host.
Why planning matters here.
Additions fail when feasibility, engineering, and finishes are handled by separate vendors who never talk to each other. We do all of it in-house — so the roofline ties cleanly, the HVAC zone is right-sized, and the finishes in the new space match the rest of the home. One accountable team, one schedule, one budget.
FAQ
DFW home addition questions, answered.
How do I know if an addition makes sense for my house?
Three things drive it: lot setbacks and easements, your foundation, and how the addition ties into existing roof lines, HVAC, and electrical. We walk the property, pull plat and survey info, and give you a clear feasibility answer — what's possible, what's not, and roughly what it costs — before you spend money on full drawings.
How long does a home addition take in DFW?
Most additions run 5–9 months end-to-end. Plan on 6–10 weeks for design, engineering, and permitting; 4–7 months of construction depending on size, foundation type, and whether we're going up or out. We give you a written schedule with milestone dates before you sign.
What does a home addition cost?
Cost depends on size, foundation, roof tie-in, and finish level — but most DFW additions land between $350 and $600 per square foot for a standard primary-suite or family-room addition, and higher for second-story or kitchen expansions. We provide a real line-item budget after the feasibility walkthrough, not a placeholder per-foot number.
Can you do a second-story addition on my existing home?
Sometimes — it depends on the existing foundation and framing, lot coverage rules, and HOA review. A second story is one of the highest-impact adds when the structure supports it. We assess the foundation and framing first and tell you honestly whether it pencils out.
Will I have to move out during the addition?
Usually no, but it depends. For most primary-suite, family-room, or kitchen additions families stay in the home — we dust-contain the work area, protect adjacent finishes, and stage materials away from daily-use spaces. For full second-story adds or large reframes that disrupt HVAC and electrical, we'll talk through the trade-offs honestly so you can plan.
Do you handle the architect, structural engineer, and HOA submittals?
Yes. Design, structural engineering coordination, city permitting, and HOA architectural review packets are all handled in-house or by our regular partners — you get one point of contact, not five vendors to chase.
Which DFW cities do you build additions in?
Grapevine, Southlake, Colleyville, Fort Worth, Keller, North Richland Hills, Dallas, Westlake, and the surrounding North Texas communities. We know each city's permit office and the HOA review process in the most common neighborhoods.
