What We Build
Dallas Home Additions, Done Right
A home addition only works if it reads as part of the original house. Matching the roofline, the window trim, the brick or stone, and the eave detail is where most additions break down. We design and build additions in Dallas with those details locked at the start so the finished build feels intentional from the curb in.
Whether you are adding a single room, putting a second story over an existing footprint, building a casita off the main house, or converting a garage into living space, the structural tie-in and the exterior continuity separate a real addition from a bolted-on extension. We sequence demolition, structural connection, mechanical integration, and finish work so the work inside lands as cleanly as the work outside.
Addition Types
What's Included
Room Additions
Adding a primary suite off the back of the house, a sun room off the family room, or a kid's bedroom over the garage. Foundation, framing, and roof tie-in get designed alongside the interior layout so the new room feels like it always belonged.
Second-Story Expansions
Going up rather than out on a tight lot. Existing first-floor framing gets inspected and reinforced where needed before the new floor system goes on. We coordinate staircase placement and HVAC zoning so the second story works as part of the home.
Attached Suites and Casitas
Mother-in-law suites, guest wings, and attached casitas off the main footprint. Separate climate control, kitchenettes, and private entries all get specified at design so the addition serves its actual purpose.
Garage Conversions
Turning a two- or three-car garage into living space, often with a new garage built elsewhere on the lot. Insulation, finished floors, HVAC extension, and the slab-to-living-space transition all need to land cleanly.
Roofline and Exterior Match
The visible difference between a good addition and a bolted-on box is the exterior. We match the existing roof pitch, brick or stone tier, window trim profile, and eave detail so the addition reads as part of the original house.
Mechanical Integration
HVAC zoning, electrical panel capacity, plumbing branches, and the load calcs that determine whether the existing systems can serve the addition or need upgrades. Permits, inspections, and the upgrade work all run under the same contract.
How We Work
The Addition Build Process
Four stages, fully transparent. No surprise change orders, no mystery line items.
- 01
Consultation
We walk the existing house, talk through what the addition needs to do, and assess what the lot allows in terms of setbacks, height, and impervious cover.
- 02
Design & Fixed Pricing
Stamped structural drawings, exterior matching specs, mechanical integration plan, and a line-item budget all get locked in writing before demo.
- 03
Build
Demolition, structural connection, framing, mechanicals, and finish work get sequenced so the existing house stays livable when possible.
- 04
Walkthrough & Warranty
Final punchlist signed off together, then the documented warranty handoff. 1 year on all work, 2 on systems, 10 on structural.

FAQs
Addition Questions, Answered
How long does a home addition take?
Most additions run 3 to 8 months from break-ground to closeout. Second-story expansions and full attached suites usually run longer than single-room additions because of the structural and mechanical scope. You'll have a written schedule before construction begins.
Can we keep living in the house during the addition?
Usually yes for room additions or garage conversions, where the new work happens outside the existing envelope. Second-story expansions and additions that require opening the existing roof are harder; we'll be honest about it at design and help you plan around it.
How much do home additions cost?
Pricing scales with square footage, the structural work required to connect to the existing house, and how much mechanical capacity has to be added. Our DFW home remodeling cost guide covers the ranges we see in 2026.
Will the addition look like part of the house?
That is the whole job. Roof pitch, brick or stone tier, window trim profile, and eave detail all get matched at design. We source materials to match the existing rather than the closest stock option.
Do I need a permit for an addition?
Yes. Additions need a building permit plus stamped structural drawings, energy compliance, and inspections at each stage. We pull permits, coordinate inspections, and stay accountable for sign-off.
