Home additions in Mistletoe Heights
Most blocks here have historic review, and the narrow lots put additions in back. We check your address first.

What a home addition in Mistletoe Heights involves
An addition either disappears into the house or announces itself forever, and which one you get is settled on the drawing board rather than at the paint store. Rooflines, window proportion, brick coursing, the way the new eave meets the old one. Get those right and nobody can find the seam. Get them wrong and everybody can.
Which is the good part, because the list of things an addition can be is long: a primary suite the plan never had, a second story on a lot too small to grow sideways, a sunroom, a bigger kitchen, a real home office, an in-law suite for a family that got closer together. Our team draws it, walks the permit through the city, and builds it.
In Mistletoe Heights
An addition is the Mistletoe Heights project where the rules genuinely bite, and which rules depends on your address: about two-thirds of the neighborhood sits in the city's historic overlay, where the street elevation is reviewed before a permit is issued, and one corner carries no overlay at all. The lots are about 58 feet wide at the median either way, so additions here go back, and sometimes up. We check your address and draw the massing against the guidelines before we price anything.
Design and drafting, in house
The drawings come from the people who have to build them
Plans, elevations and selections are done here, by the team that will be on site — so the thing you approve on paper is the thing that gets built, and the number under it is real.

What the houses here actually ask for
1922
A genuinely pre-war neighborhood — the median house dates to 1922, four in five went up before 1940, and the original deed restrictions banned frame construction, which is why brick and stucco run these streets.
Houses this old have good bones and a floor plan built for another century. Most of the work here is reorganizing what's already there, carefully — and knowing exactly which rules apply to your address before anyone draws.

The ground rules in Mistletoe Heights
About two-thirds of the neighborhood is in the historic overlay. One corner is not.
This is an address question, never a neighborhood one, and it is the first thing we check. Inside the overlay, exterior work needs a Certificate of Appropriateness before the permit issues. Outside it, the standard permit path applies. Anyone who answers this from the neighborhood name is guessing with your schedule.

Your front setback is set by your neighbors, not by the table
Fort Worth's contextual front-yard rule lets the required setback follow the block face rather than the base 20 feet. It is the rule that most often moves a Mistletoe Heights addition on paper, and it is not something you can read off a zoning map — it comes from measuring the houses on either side of you.

What it runs in Mistletoe Heights

a bump-out at the low end, a full second story at the top.
Ranges for a home addition in Mistletoe Heights, not a quote. Before there are drawings, a range is the only honest number anyone can give you — the spread between a high and a low bid on the same job is routinely 20% or more. We bill cost-plus, so when there is a plan you see the actual materials, labor and subcontractor costs, plus our overhead and profit, rather than a single figure with the unknowns padded into it.
What moves it
- Which kind of addition. A bump-out borrows the roof and structure you already have; a second story needs engineering, a staircase, a new roofline and every system re-integrated.
- Whether a bathroom is in it. Plumbing into new square footage is $15,000–$35,000 on its own, and how far it sits from existing lines decides where in that band you land.
- What the existing house can carry. Whether the foundation extends, whether a bearing wall is in the way, and whether the framing can take a floor above it are answers that come from opening things up, not from the curb.
- Matching the character. In the neighborhoods with an overlay — Ryan Place and Mistletoe Heights among them — custom millwork and matched exterior materials add 10–15%.
- Per square foot

The moves that matter in Mistletoe Heights
Every neighborhood rewards something different. These are the three that come up on almost every home addition we take on.
-
Back, and sometimes up
The lots are long and narrow, about 58 feet at the median, so a side addition is almost never the answer here.
-
Draw the massing before the budget
On overlay addresses the street elevation and height are reviewed before a permit issues. We draw the massing to be approved the first time, not revised into it.
-
Measure the neighbors' setback
On a 1920s block your buildable front line is set by your neighbors' houses, not by the zoning number. It is the cheapest thing on the job to get wrong.
Both numbers, one conversation
Remodel it, or sell it?
You love the street. The house is the question — and in a pre-war neighborhood, it's a real one.
What the work would cost
Priced by the people who'd build it.
Design, drafting and construction, in house.
What it'd sell for as-is
Valued by the agents who sell this market.
6th Ave Homes is a licensed brokerage.
A remodeler can price the work. An agent can price the house. We do both.
We're one of the few companies in Fort Worth built to answer it straight — our agents sell in this market and our design and construction teams price the remodel, so you can weigh a real renovation number against what the house would actually sell for. Sometimes the answer is a second story. Sometimes it's a listing. We'll tell you which one we'd pick and why.
How it works
A home addition in Mistletoe Heights, in three steps
The people who draw it, price it, and build it share a hallway — which is why the plan you fall in love with is the plan that actually gets built.
Meet Up
We walk the house, listen to how you actually live in it, and talk honestly about budget before anyone draws a line.
Team Up
Our designers and drafting team put a real plan on paper — layout, selections, and a number you can build around.
Glasses Up
We build it, keep you in the loop, and hand back a home that feels like you. Pour something good.

Mistletoe Heights Kitchen & Primary Expansion
Home Addition
When a historic home runs short on room, the answer is space that respects what's already there. In Mistletoe Heights, the 6th Ave Homes team expanded the kitchen and primary suite in keeping with the home's era, and the images carry the rest.

The neighborhood
A hundred years old, on the bluff over the Clear Fork.
Mistletoe Heights sits on the bluff above the Clear Fork, and the ground does what that sounds like — the western edge drops sixty to seventy-five feet before it flattens onto the plateau the rest of the neighborhood sits on. The Trinity Trails run along the bottom of it.
Forest Park physically adjoins the neighborhood. The zoo, Trinity Park and the Botanic Garden are all about a quarter mile out, Log Cabin Village a little further, and the Forest Park miniature railroad has been running across the Clear Fork since 1959.
Lily B. Clayton opened in February 1922 as Mistletoe Heights Elementary and is a city landmark. It starts what everyone here calls the Paschal pyramid — Clayton, then McLean 6th Grade, then McLean Middle, then Paschal — and it is the reason a lot of families give for moving here in the first place.
The lots are narrow by modern standards, a median a little under fifty-eight feet wide against about a hundred and thirty-five deep, and one in six is under fifty feet. A third of the houses record no garage at all. Both facts decide more projects here than taste does.

What that means for your home addition
Adding on here is a narrow-lot problem. The median lot runs a little under fifty-eight feet wide, so an addition goes back rather than out — and the back of these houses is exactly where the original service porch and somebody's 1950s bathroom already are. Getting a primary suite in without ending up with a hallway house is the entire job.

Is my Mistletoe Heights house actually in the historic district?
That's an address question, not a neighborhood one — and it's the first thing we check. About two-thirds of Mistletoe Heights sits under the city's historic overlay; one corner opted out at designation and carries no overlay at all. If your address is inside it, exterior work needs a Certificate of Appropriateness before the permit. If it isn't, the standard permit path applies. Anyone who answers this from the neighborhood name is guessing with your schedule.
How much can I actually add, and where?
Back and up, in practice. The lots here are long and narrow, so a side addition is rarely the answer — and if your address sits in the overlay, the street elevation and height get reviewed. What's genuinely achievable is a per-lot question and a drafting question before it's a construction one. We draw it before anyone commits to a budget.
How close to the street can an addition or new build sit?
Closer-to-the-street is where front additions on these blocks get stopped, because the required front setback here isn't one number. Fort Worth takes the greatest of the platted line, the district minimum, and a projected line drawn from the neighboring houses, up to a 50 foot maximum. On a 1920s block the neighbors' line almost always governs. We measure the neighboring setbacks before we draw, because finding that line during construction instead of before it is how a project loses months.
Does the review add time to the schedule?
On overlay addresses it adds a real step with a real calendar, and it's very manageable when the drawings anticipate it rather than discover it. That's the practical advantage of the people who draw your plans sitting down the hall from the people who build them — the submittal is drawn to be approved the first time.
Does finishing an attic or a garage count as an addition?
Yes, and the appeal is obvious: the roof and the slab are already there. What is less obvious is that both need real insulation, HVAC, egress, and a floor system that was never designed to be lived on, which is where a conversion stops being a weekend project.
What does an addition cost us in yard?
More than most people picture. Stake the footprint and stand in what is left before you fall for the plan, because a drawing makes twelve feet look like nothing and the back garden is often the reason people bought the house.
