THE SHORT VERSION

Birdseye Construction builds home additions across Fort Worth and North DFW — bump-outs, room additions, second stories, and primary suites — under one design-build contract. Most Fort Worth additions run $150 to $400 per square foot depending on whether you build up or out, with a fixed price set before demolition begins.

Additions we build in Fort Worth

Fort Worth housing stock runs from 1920s Craftsman bungalows near the urban core to 1990s tract homes in the Alliance corridor to newer builds on acreage north of Loop 820. Each one fails the family differently, and each one needs a different addition.

Bump-outs — two to fifteen feet added to one room. The cheapest way to fix a cramped kitchen or bathroom.
Room additions — a new bedroom, office, playroom, or family room on new foundation.
Second story additions — the answer when the lot is full and the family is not.
Primary suite additions — bedroom, full bathroom, and walk-in closet as one suite.
In-law suites and ADUs — independent living space for aging parents or adult children.
Garage conversions and bonus room finish-outs — square footage you already own.

These are typical Fort Worth ranges, not a quote. Every Birdseye addition is priced under a fixed-price contract after a walkthrough and design — the number you approve is the number you pay.

Permits and inspections in Fort Worth

Additions in the City of Fort Worth require a building permit, and most require an engineer’s stamped drawings for the foundation and framing. Depending on where the house sits, the project may also touch Tarrant County or Denton County requirements, a historic overlay district, or an HOA with its own architectural review. Birdseye pulls the permits, carries the drawings through review, and schedules every inspection as part of the contract — the homeowner is not left standing in line at a permit counter.

Why homeowners hire Birdseye

We are a design-build contractor, which means design, engineering, permitting, and construction sit inside one contract with one point of accountability. There is no separate architect bill, no gap between the drawing and the build, and no finger-pointing when the two do not match. We run in-house crews on the core trades, and we price the job as a fixed amount before demolition — not as a cost-plus estimate that grows.

Frequently Asked Questions

How long does a home addition take in Fort Worth?

Plan on four to seven months end to end. Design and engineering take two to six weeks, permitting in Fort Worth typically runs three to eight weeks depending on scope and review load, and construction runs 14 to 28 weeks depending on the addition type.

Do I need an architect for a home addition in Fort Worth?

You need permit-ready drawings and, for most additions, an engineer’s stamp on the structural work. As a design-build contractor, Birdseye provides both inside the construction contract rather than as a separate architectural fee.

Can I stay in the house during an addition?

Usually yes. Additions are built outside the existing envelope for most of the schedule, so the house stays livable until the connection is opened. Second story additions are the exception — there is typically a period during roof work when staying elsewhere is easier.

Will an addition require a new foundation?

Ground-floor additions need new foundation. Second story additions need the existing foundation and framing evaluated by an engineer to confirm they can carry the load, and reinforcement is common. That evaluation happens during design, before the price is fixed.
