Home Additions · Fort Worth

Add the room your house has been missing

When you’re out of space but not out of love with your home, an addition is the answer — a primary suite, a second story, a bigger kitchen, a room that finally exists. We design, draw, permit, and build it under one roof, matched to the house you’ve already got.

Done right, nobody can tell which part you added.

The stuck part

Need more space — but not more stress?

You’re bursting at the seams. The new baby, the parent moving in, the home office that’s really a corner of the bedroom. Moving means leaving the street and the schools you chose.

But an addition has its own landmines: will it match the house, will the city allow it, where does the roofline go, and who keeps the new part from looking bolted on? Done wrong, an addition looks like an addition. Done right, the house looks like it was always that size.

Three directions

Every addition goes up, out, or over

Which one you get is usually decided by the lot before anybody draws anything. It’s also the decision that sets your budget and your structural risk — so we settle it on the first walkthrough, not three weeks into design.

Up

When the lot is full

A second-story or pop-top addition, which on Fort Worth’s smaller historic lots is often the only direction left. It’s the heaviest structural lift: the existing foundation and framing have to carry a floor they were never asked to carry, so it starts with the engineering rather than the floor plan.

Out

When the yard can spare it

A rear addition, a bump-out, a sunroom, a primary suite off the back. Simpler structurally, but it’s the direction the city has the most to say about: setbacks, lot coverage, and in a historic district, what the new roofline is allowed to look like.

Over

When it’s already there

A garage conversion, an attic conversion, a room built over the garage. The cheapest square footage you will ever add, because the roof and the slab already exist. Often the honest answer when someone asks for an addition and what they actually need is a room.

What’s included

The engineer, the permit, and the crew are all ours

Every addition we take on is full-service from day one. You won’t be chasing engineers, sitting in permitting, or coordinating five vendors who’ve never met.

  • 01

    Space planning and custom layout

    We start by reading how the house flows now and how it could flow better — then draw a layout that fits your lot and the way you actually use the place.

  • 02

    Scaled floor plans and 3D renderings

    You see the addition before it exists: dimensioned plans, elevations, and full-color 3D views. Decisions get made on a screen instead of on site.

  • 03

    Zoning research, permits, and city approvals

    Setbacks, lot coverage, overlays, and the submittal itself — including historic-district coordination where it applies. We do the counter work.

  • 04

    Foundation, framing, and structural tie-ins

    New slab or pier-and-beam, and the connection back into the existing structure. Going up means proving the house below can carry it.

  • 05

    HVAC, plumbing, and electrical integration

    The new space ties into the systems you already have — or tells you when the panel or the unit can’t take another room.

  • 06

    Exterior finish matching

    Brick, siding, roofing, windows, paint, and trim matched to the house. This is the line between an addition and a box bolted on.

  • 07

    Interior finishes, storage, and lighting

    Cabinetry, built-ins, tile, hardware, and a lighting plan — so the new room reads as part of the house instead of the newest room in it.

  • Not sure how much of this you need?

    Most people don’t, on the first call. We walk the house, tell you which of these your project actually pulls in, and price only that.

The difference

An addition that belongs, or a box bolted on

The cheap version: a contractor frames new square footage that clashes with your roofline, your brick, and your windows — and now the house looks patched. Every drive up to it is a small reminder.

We design the addition to match the home and draw it to permit, so it reads as original, not as the part you added. And because we draft in-house, you’re not paying an architect to draw what a separate contractor then re-prices.

What it’s really for

Nobody adds on because they want more square footage

They add on because somebody needs a room. Almost every addition we build traces back to one of four reasons, and knowing which one is yours changes the whole drawing.

The primary suite the house never had

A 1920s bungalow wasn’t drawn around one. A suite addition is the single most common thing we’re asked for, and the one that changes the day-to-day most.

Room for your parents

An attached in-law suite keeps family close without putting everybody in the same hallway. Privacy, a real bathroom, and its own way in.

An office that isn’t the dining table

Working from home stopped being temporary. A room with a door, wired for it, is worth more than the square footage suggests.

A kid who finally gets their own

Sometimes the whole project is one more bedroom, and going up is the only direction the lot allows. That counts as a reason.

From walkthrough to walkthrough

How an addition actually goes

Meet Up

We walk the house and the lot together, talk through the space you actually need, and tell you what zoning and setbacks will really allow before you get attached to an idea.

Team Up

Our drafting and design teams plan the addition to match the house, coordinate the structural engineering, and put a real number on it — one Game Plan, one price.

Glasses Up

We build it and blend it in — brick, roofline, trim, and finishes — so the new space stops reading as new and starts reading like it was always part of the house.

The number

What a home addition costs in Fort Worth

Adding square footage spans a wide range — a bump-out or sunroom is one number, a full second story or a primary-suite wing is another. We bill cost-plus with a transparent markup, so you get a real number before we break ground.

Up or out

Going out buys foundation and roof. Going up buys structural work on the house that is already standing. They are different projects with different numbers, and the lot usually picks for you.

How much square footage

A bump-out or a sunroom is one order of magnitude. A full second story or a primary-suite wing is another. Size moves this more than any finish decision will.

What the room has to do

A bedroom needs walls and a closet. A suite needs plumbing, a kitchen needs gas and venting, and every one of those pulls the systems work along with it.

How hard the match is

A painted-siding ranch is a straightforward match. A 1925 brick bungalow in a historic district, with a roofline the city reviews, is not.

Where we build

Neighborhoods where we’ve already done this

Additions are construction, so our radius is the crew’s radius — Fort Worth and the close-in towns. Ryan Place, TCU, Mistletoe Heights, Arlington Heights and Tanglewood come up most, because those are the streets people refuse to leave.

The question under the question

Is it cheaper to add on, or to move?

It’s the decision almost everybody is actually making. Nobody wants an addition — they want the room, on the street they already chose.

Often adding on keeps you in the neighborhood you chose and beats buying-and-renovating elsewhere — and because we’re also a brokerage, we can run that comparison with real numbers for your area.

What your house would list for. What the bigger one down the street would actually cost you after you fixed it. What the addition runs. Same team, one conversation — and if the numbers say move, we’ll tell you that too.

Good questions

Before anybody swings a hammer

The ones that come up on almost every first walkthrough.

What we can add

Can you add a second story?

Yes — second-story (pop-top) additions are a core service, especially on Fort Worth’s smaller historic lots where you can’t build out.

Can you turn my garage or attic into living space?

Yes — garage and attic conversions are some of the most cost-effective ways to add a room, and they extend what we already do best.

Can you add a primary suite, in-law suite, or home office?

Yes — primary-suite additions, attached in-law suites, and home-office additions are among the most common.

Will my lot even support an addition?

We research your setbacks, lot coverage, and overlays before design — in Ryan Place, Mistletoe Heights, and Tanglewood especially — so we know what’s buildable from day one.

Will the addition match my house?

That’s the whole point — we match brick, siding, roofline, windows, and trim so it reads as original, not bolted on. Especially critical in historic neighborhoods.

Cost, time, and living through it

How much does a home addition cost in Fort Worth?

Wide range — a bump-out or sunroom is one number; a full second-story or primary-suite addition is another. It tracks the size, whether we go up or out, foundation and roof work, and finish level. Cost-plus, real number before we break ground.

How long does an addition take?

Depends on size and whether we’re going up (structural) or out (foundation); you get a real schedule up front.

Do you handle zoning, permits, and city approvals?

Yes — all of it, including historic-district coordination where it applies.

Do I need an architect?

Usually not — we draft in-house and coordinate the structural engineering.

Can we live in the house during the addition?

Often yes, since an addition is frequently sealed off from the living space until tie-in — we’ll tell you which one yours is before you plan around it.

The rest of the house

An addition touches every part of this company

Drafting draws it to permit, design matches it inside and out, construction builds it, and the brokerage can tell you what the added square footage does to what your home is worth. From “can my lot handle this?” to the final walkthrough, it’s the same building.
