Additions from North Texas Custom Builders
North Texas Custom Builders builds home additions in Grapevine, TX and across DFW: extended dining and living rooms, primary suites and extra space tied into the house you already have. Owner Perry Roberts started as a framer, so the hard part of an addition, joining new framing and roof to old, is the part he knows best.
Who it's for
Families who like where they live but have run out of room: a dining room that can't seat everyone, no space for a parent, or a primary suite that never was.
Who it isn't for
If the house needs more than double its current size, building new on the lot can cost less. We will tell you if that's the case.
What's included
- Room additions that extend a dining room, living room or kitchen
- Primary suites and extra bedrooms with their own bath
- New framing and roof tied into the existing structure
- Matching brick or stone, windows and rooflines
- Finishing the connected rooms so old and new read as one house

What clients said about additions
5.0 from 4 verified reviews on Angi
“They also did an addition which extended my dining room, laid new floors, new roof, new windows and remodeled my laundry room. Perry is knowledgeable, stands behind his work and employees. He oversees all work. They protect your home by using plastic as barrier and daily sweep up and clean up the work site. I have used other contractors before but since finding North Texas Custom Builders, I will only use them.”

“I have hired NTXCB's multiple times. Projects include major renovations and expansion of my home and various commercial tenant finish outs. They are top of the mark. Will definitely hire them again.”

Good to know
How do you make an addition look original?
Three things give an addition away: a roofline that doesn't line up, brick or stone that doesn't match, and windows of a different style. All three get decided before the slab is poured, not after the walls are up.
Should I add on or build new?
An addition makes sense when you like the location and the house is sound. When the foundation, roof and layout all need work at once, a new custom home on the same lot can be the cheaper path. That is the one question a builder who does both can answer honestly.

Additions questions
How much does a home addition cost in DFW?
A 2026 Dallas guide puts ground-level additions at about $120 to $240 per square foot and second-storey additions at about $200 to $400 per square foot. Those ranges are not a quote from North Texas Custom Builders. Your price is confirmed in writing before work starts.
Will the addition match my existing house?
Yes, that is the point of a good addition. The roofline, the brick or stone and the window style are matched to the existing house and decided before the slab is poured.
Do I need a permit for a home addition in Grapevine?
Yes. A room addition in Grapevine needs a building permit and inspections from the city. The builder normally pulls the permit and books the inspections as part of the job.
Can we stay in the house while the addition is built?
In most cases, yes. On a typical addition the new space is framed and dried in outside the existing walls first, and the opening into the house comes late, sealed off with plastic while the work is finished.
