THE SHORT VERSION

Home additions in Grapevine, TX run $185–$400+ per square foot — main-floor additions, second-story additions, and in-law suites — with smaller projects at the higher end because engineering, roof work, and tie-ins are fixed costs. Birdseye Construction designs and builds them on a fixed-price contract, with a structural engineer’s evaluation up front and permits pulled for you.

What a Home Addition Costs in Grapevine

We publish real numbers because guessing helps no one. Every addition is priced as a fixed-price contract — the number you sign is the number you pay, with any change you request handled through a documented, signed change order.

Addition Type	Typical Cost	What to Know
Main-floor addition	$185–$400+ per sq ft	Bedrooms, family rooms, kitchen and dining expansions — built on an engineered foundation tied into the existing structure.
Second-story addition	upper end of range	Adds space without losing yard — requires a structural evaluation of the existing foundation and framing first.
In-law / guest suite	$185–$400+ per sq ft	Bedroom, bath, and living space for multigenerational living — zoning confirmed with the City of Grapevine before design.

Why smaller additions cost more per square foot: engineering, roof tie-ins, and stairs are fixed costs whatever the size — larger footprints dilute them. The National Association of Home Builders puts home additions at roughly 65–75% of cost recouped at resale.

Built on Engineering, Not Guesswork

Every Birdseye addition starts with a structural engineer’s evaluation of your foundation and framing, and every permit is backed by engineering-stamped plans — with North Texas soil conditions accounted for from the foundation up. You don’t need to hire an architect separately: design happens in-house, so design, engineering, and construction stay under one contract and one fixed price.

Room Additions for Growing Grapevine Families

Most Grapevine addition calls start the same way: the family outgrew the house, but nobody wants to leave the neighborhood. We design and build the bedroom, family room, or in-law suite that lets you stay — matched to the existing house, whether it’s a historic cottage near Main Street or a newer build, so the addition looks like it was always there.

How the Process Works

An initial consultation at your home — a structural evaluation and fixed-price quote — the in-house design phase with every material selected and approved — permits pulled by us through the City of Grapevine — then construction, with city inspections passed at every required stage and a final walkthrough before we call it done.

Frequently Asked Questions

How much does a home addition cost in Grapevine, TX?

Home additions run $185–$400+ per square foot — smaller projects sit at the higher end because engineering, roof work, and stairs are fixed costs. Every Birdseye addition is quoted as a fixed price before work begins.

Can you add a second story to my house?

Usually, yes — it starts with a structural engineer’s evaluation of your foundation and framing. If the structure supports it, a second-story addition adds space without losing any yard, with engineering-stamped plans behind the permit.

Can you match an addition to an older Grapevine home?

Yes — matching rooflines, brick, and trim on established homes is a point of pride. The addition is designed in-house to look original to the house, not bolted on.

Who pulls the permits for an addition in Grapevine?

We do. Birdseye is registered with the City of Grapevine and provides the city its list of licensed trades before work is released for construction.

Should I build an addition or move to a bigger house?

Homes are priced by the square foot — if you love your neighborhood, building onto what you own usually wins: no commissions, no moving costs, and you keep your mortgage rate while every dollar becomes space you designed.
