01 · Before — an open yard, a tired patio
The homeowners came to us with a classic mid-2000s Dallas County brick home: a great floor plan, mature shade trees, and a generous side yard begging to be put to use.
The back of the house had an undersized concrete pad, the arched feature window overlooked nothing in particular, and the family was running out of room.
The goal: add square footage without making it look like an addition.
02 · During — foundation to finish, in order
A good addition isn’t a project — it’s a sequence. Site layout, foundation, plumbing rough-in, framing, roof tie-in, dry-in, envelope, MEP, insulation, drywall, and finish.
Skip a step and the whole stack suffers. Here’s how the Grand Prairie build went, in the order it happened on-site.
Step 01 — Layout & site prep
Batter boards and string lines establish the addition’s exact footprint, setbacks, and finished floor elevation before a single shovel of earth gets moved.
Step 02 — Plumbing rough-in
Drain and supply lines routed for the master bathroom — every fixture located before concrete locks them in.
Step 03 — Concrete prep
Patio formwork built tight to the house, with plumbing supplies staged for the addition slab pour.
Step 04 — Slab & rebar
Engineered rebar grid in place for the ADU slab.
The patio slab is already finished — visible in the background.
Step 05 — Concrete poured
The new patio concrete, freshly troweled.
This becomes the floor under the new flush patio cover.
Step 06 — Framing begins
Bottom plates locked in.
The first wall is up and braced — the addition starts taking shape.
Step 07 — Walls go vertical
Wall framing raised by hand, plumbed, and braced.
Step 08 — Full framing complete
All four walls of the addition framed, ceiling joists set, and the new structure was tied into the existing house.
Roof framing comes next.
Step 09 — Roof tie-in
The roof tie-in is what makes an addition disappear — done right, you can’t tell where original ends and new begins.
Step 10 — Matching brick delivered
Brick sourced and matched to the existing veneer.
The wrong brick is the fastest way to make an addition look like an addition.
Step 11 — ZIP System dry-in
ZIP System structural sheathing provides the air- and water-resistive barrier in one product — taped seams and all.
Step 12 — Side elevation, fully dried in
The addition fully sheathed and dried in.
The transition to the existing brick is mapped, and brick masons are ready.
Step 13 — Roof shingled to match
Architectural shingles installed, color-matched to the existing roof.
The arched-window section reads continuously from the street.
Step 14 — Patio cover framed flush
The patio cover rafters tie directly into the existing fascia and roof structure — flush, not bolt-on.
From the yard, the cover reads like it was always there.
Step 15 — Closed-cell spray foam
High-performance closed-cell spray foam in walls and roof cavity.
In Texas heat, the envelope is everything.
Step 16 — Master bath waterproofing
CertainTeed GlasRoc backer with waterproofed seams on the master shower — the right substrate behind every tile, and a standard on every master bathroom remodel we build.
Step 17 — Interior takes shape
Inside the new bedroom: drywall up, crown molding installed, a new window letting Texas light into a room that didn’t exist 90 days earlier.
The best additions aren’t noticed. Walk the back of the house, and the new ADU reads like it was drawn into the original plans — same roofline, same brick, same hand.
03 · After — a seamless connection, designed to live in
The finished addition connects to the original home through a soft arched hallway — the same arch motif as the existing feature window, carried through to the new wing.
Below is the connecting hallway and the design intent renderings for the master bedroom: warm gray walls, twin windows, a double-barn-door walk-in closet, and a master bath tucked behind the bedroom.
The connector hallway, finished — Arched entries on both sides match the original home’s arched feature window. Dark hardwood, flush-mount lighting, fresh paint throughout.
Master bedroom · design intent — Twin windows flanking the bed, soft gray walls, and a single-track barn door leading to the walk-in closet.
Master bedroom · the other wall — Double barn-door walk-in closet, TV wall over a white dresser, and a doorway to the master bath on the far left.

Built for Grand Prairie, the way Grand Prairie builds.
Grand Prairie sits in Dallas County between Arlington and downtown Dallas, with housing stock that runs from 1990s production builds in 75052 to newer construction in 75054.
Most additions in this part of the metroplex involve matching a 20-to-30-year-old brick veneer, working around clay-heavy soils that demand engineered slabs, and tying roof framing into a home where the existing trusses weren’t designed with an addition in mind.
Every residential addition in Grand Prairie — including covered patios — requires an approved permit from the City of Grand Prairie Building Inspections Division.
Home Build and Designs handles permitting, engineering, and inspections on every job we run, from a single room to full ADU construction in Grand Prairie.
Service Area: Grand Prairie · Arlington · Mansfield · Cedar Hill · Duncanville · Irving · Dallas · Fort Worth · Mesquite · DeSoto · Midlothian · Burleson
Frequently Asked Questions
What was included in this Grand Prairie ADU addition project?
The addition included a new living room, a bedroom with a walk-in closet, and a master bathroom.
The outdoor scope added a new concrete patio surface and a patio cover that ties in flush with the existing home roofline.
Do you need a permit for a home addition in Grand Prairie, TX?
Yes. The City of Grand Prairie Building Inspections Division requires an approved residential addition permit for any added living area — and that includes decks, patios, and covered porches.
Home Build and Designs handles permitting on every addition we build in Grand Prairie.
How long does an ADU addition like this take to build?
A typical permitted ADU addition of this scope — roughly 400 to 600 square feet with full plumbing, electrical, and a tied-in roof — runs 12 to 20 weeks from permit issuance to final inspection.
Weather, inspection backlogs, and selection lead times are the most common variables.
Can a patio cover be built flush with my existing roofline?
Yes. A flush patio cover ties new rafters into the existing roof structure so the new cover reads as part of the original house rather than an attached awning.
It requires engineered framing, matching soffit and fascia, and (in most cases) reshingling the tie-in area.
That’s exactly what we did on this Grand Prairie build — see how our flush patio cover installation across Dallas–Fort Worth is done.
Does Home Build and Designs serve cities beyond Grand Prairie?
Yes. We serve the greater Dallas–Fort Worth metroplex, including Arlington, Mansfield, Cedar Hill, Duncanville, DeSoto, Irving, Dallas, and Fort Worth.
Most of our project pipeline is within a 50-mile radius of Grand Prairie.
How do you make a new addition match an older brick home?
Three things matter most: brick match, roofline continuity, and trim/detail carry-over.
It’s the same eye we bring to every exterior home renovation in Grand Prairie: we source brick from yards that stock or can pull legacy runs, design the roof tie-in so pitches and overhangs align, and continue trim, fascia, and architectural details from the original.
On this Grand Prairie home, we even mirrored the existing arched-window motif into the new connector hallway.
Does Grand Prairie allow ADUs (accessory dwelling units)?
Yes. Grand Prairie permits them, though the city’s Unified Development Code calls them “accessory apartments” rather than ADUs.
An accessory apartment can be added inside an existing single-family home or built as a separate structure on the same lot, as long as it functions as a complete, independent living space.
Under the city’s code, an accessory apartment must be at least 400 square feet and cover no more than 35% of the original home’s total floor area, have no more than two bedrooms, provide one parking space per adult resident, carry certified water and sewer service, and keep the owner living in one of the two units.
There’s also no single “ADU program” with grants or incentives — it’s handled through the City of Grand Prairie’s standard permitting process, which we manage for you as part of the build.
Because requirements can change and depend on your specific lot and zoning, we always confirm the current rules with the city before design.
Planning an addition in Grand Prairie or the Dallas–Fort Worth metroplex?
We design, obtain a building permit (in compliance with zoning regulations), and build everything from accessory dwelling units and outdoor living spaces to full home remodels across Dallas–Fort Worth.
