What should Flower Mound homeowners know before building a backyard?
Flower Mound has real elevation change on a lot of its lots. Grade is the first thing we solve: retaining and drainage, then the pool, then everything that sits around it.
That ground decides how a slab, a pool shell or a footing has to be built here. Here is what it does to a patio.
In Flower Mound the job is reviewed by the Building Inspections Department, and we file and follow the permit through that office ourselves. Flower Mound requires a permit for any in-ground pool, for an above-ground pool deeper than 24 inches, and for hot tubs and spas. Our permit guide lists the office for every city we have checked.
Longhorn has built across Denton County and the wider Metroplex since 1984, and every project starts with a free design visit and a firm price.

How a Backyard Project Runs in Flower Mound

A free design visit in Flower Mound
A designer comes out to the house, measures the space a backyard project has to fit, walks the access a crew would need, and talks through what you want it to do. You leave with a firm price. On Eastern Cross Timbers ground, that is also when the grading, drainage and movement details get decided rather than improvised on site.

Drawings, permit and HOA
We file the permit with Building Inspections Department at the City of Flower Mound and follow it through review. Where an HOA wants a submittal, we prepare the drawings it asks for.
- 3
One crew, one schedule
The same team builds the whole backyard project in order, so the slab, the structure, the electrical and the finish work are not three different companies working around each other.

Walkthrough and warranty
We walk the finished backyard project with you, settle the punch list and leave one warranty on the work, and we are still Denton County-local if you need us later.
Homes and Yards in Flower Mound
Flower Mound is a residential suburb that grew rapidly after 1970; its 1970s planned new town on the north shore of Grapevine Lake became the Timber Creek community.
Yards from those decades are usually established, with grown trees, a fence line and an original patio that is often too small. Most projects become a retrofit, planned around what is worth keeping.
Flower Mound borders Grapevine Lake in the Eastern Cross Timbers and is named for a 12.5-acre wildflower-covered mound. Where an older oak survives on a lot, it is an asset: its root zone is marked before any digging, and its shade goes into the layout.

Flower Mound sits on Eastern Cross Timbers ground in Denton County. The ground decides how a slab, a pool shell or a footing has to be built, so we plan the drainage and the footings for it at the first visit rather than after something moves.
