Knox-Henderson Fireplace Installation & Design — Space Fireplace Services

Knox-Henderson is the part of Dallas where the floorplate matters more than the lot size. The corridor along Knox Street, McKinney, and Cole has filled in over the last fifteen years with luxury mid-rise condos, new-build townhomes, and lofted single-family infill — most of them designed around an open great room with a single, deliberate fireplace wall. Space Fireplace Services installs into those walls. Our typical Knox-Henderson client lives in a 2,400-square-foot condo at The Ritz residences, a 3,800-square-foot Hines or Robert Elliott townhome on Travis, or a Briggs Freeman new-build off Bowser, and the fireplace is the most photographed feature of the unit. It needs to be perfect. It needs to be linear, often 60 or 72 inches, often see-through between the living and dining room, often clad in honed limestone or a poured concrete surround that runs floor to ceiling. We do that work — gas, electric, ventless when the building doesn’t allow flue penetration — and we do it with the building’s HOA, the unit’s structural engineer, and the homeowner’s designer all in the same conversation.

## A Different Kind of Fireplace Problem

A Knox-Henderson fireplace install is not a Lakewood install. The walls aren’t brick. The flue doesn’t exist yet — or, if the building was designed around fireplaces, the chase is steel-framed inside a fire-rated shaft that runs to the roof, and the venting has to terminate at exactly one approved cap location. The HOA has rules. The construction docs from the original architect have rules. The interior designer has rules. Our job is to find the unit that satisfies all three and then install it so cleanly that no one ever sees the seams.

We don’t do chimney sweeping in Knox-Henderson. Almost no unit here has a traditional masonry chimney. We do new fireplace installation, gas conversion (when an existing builder-grade unit needs upgrading), linear and see-through statement installs, and the occasional removal and replacement when a 2008-era builder fireplace looks tired next to a 2024 renovation.

## What Knox-Henderson Homeowners Actually Install

### 60-Inch and 72-Inch Linear Gas Fireplaces
The single most-installed unit in the district. A long, low, glass-fronted linear — 60 to 72 inches of flame, no visible logs, often with a black glass interior or a custom driftwood media set — anchors a great room wall the way a piece of art used to. We install Heat & Glo Mezzo and Primo, Montigo Prodigy, and the Ortal Clear series most frequently.

### See-Through Fireplaces Between Living and Dining
Knox-Henderson condos with open floorplans love a see-through unit dropped into a peninsula wall between living and dining. Glass on both sides, flame visible from both rooms, zero structural intrusion. Stuv, Ortal, and Hearth & Home Mezzo See-Through are the units we install most often. These require careful coordination with the HVAC return-air layout and the building’s fire suppression — we handle both.

### Power-Vent Direct-Vent for Mid-Rise Condos
Many Knox-Henderson condos sit too far inside the building shell to side-vent a standard direct-vent unit. Power-vent gas units — with a small inline fan that pushes exhaust through 30+ feet of horizontal venting — solve that. We’ve installed power-vent in units at The Ritz, The Stoneleigh, and several Cole Avenue mid-rises. HOA-approved termination is the make-or-break detail; we know which buildings allow what.

### Electric Linear for Buildings That Won’t Permit Gas
A handful of Knox-Henderson buildings — usually older converted office or institutional structures — won’t permit gas in residential units. For those, the electric linear category has matured into something genuinely beautiful. 60-inch and 72-inch electric units from Modern Flames Orion and Dimplex IgniteXL throw realistic flame with no venting, no gas line, and no HOA approval needed beyond the basic electrical permit.

### Gas Conversion of Builder-Grade 2005-2015 Inserts
A common Knox-Henderson scenario: the unit was built in 2010, the builder put in a standard 36-inch insert with cheap logs, the new owner is doing a $400K renovation and the old fireplace looks wrong. We remove the original unit cleanly, reframe the opening, and install a current-generation linear in its place. Two to four days on-site.

### Fireplace Removal for Loft Conversions
Lofts in Knox-Henderson sometimes have a vestigial fireplace from a previous build-out that no one wants. We remove the firebox, cap the gas, patch the venting penetration, and frame the wall flush — leaving a clean slate for the new design.

### Service and Repair on Existing Units
Pilot ignition failure, blower replacement, glass cracking from thermal cycling, remote-control board failure. We service every major brand installed in Knox-Henderson over the last twenty years.

## The HOA Conversation

Half of a Knox-Henderson install is paperwork. We’ve worked with the HOAs at the Stoneleigh, the Ritz residences, Park 17, the Travis Walk condos, and most of the major McKinney-corridor buildings. We know which require an architectural review for any vent termination on the exterior, which require a licensed fire-protection engineer’s sign-off, and which want a deposit before any contractor enters the building. We assemble the package, submit on your behalf, and don’t break ground until approval is in hand.

## Working With Knox-Henderson Designers

The Knox-Henderson design ecosystem is small and high-end. We have standing trade relationships with the firms most active in the district — the ones doing Briggs Freeman new-builds, the ones doing Robert Elliott townhome interiors, the ones working out of design offices in the Plaza of the Americas. For trade pros: we hold inventory on the linear units that ship with the longest lead times, and we’ll spec, supply, and install on a designer-confidential basis. Email for trade pricing and pre-construction consultation.

## What a Knox-Henderson Install Costs

The range is wider here than almost any other Dallas neighborhood. A clean swap of a builder-grade insert for a current-generation 42-inch linear lands at one price. A 72-inch Ortal see-through with custom honed-limestone surround floor-to-ceiling in a Ritz unit lands at four to six times that. We don’t quote sight-unseen. A free in-unit consultation gives you a fixed written number within 72 hours.

## Frequently Asked — Knox-Henderson Edition

**My HOA says I can’t penetrate the exterior wall for venting. Can I still have a real gas fireplace?**
Yes, in two ways: a power-vent unit may route to an existing approved chase, or an electric linear delivers the same visual without any venting. We’ll review your building’s documents and tell you which path works.

**My condo has a 2008 fireplace that looks dated. Can the old surround stay?**
Sometimes. If the firebox dimensions of the new unit match the existing opening within manufacturer tolerance, the limestone or marble surround can stay. More often the new unit is wider or taller, and the surround comes out. We’ll measure and confirm before you commit either way.

**Can you install a see-through fireplace between two rooms in an existing condo?**
Almost always yes, if the wall is non-structural. We coordinate with a structural engineer when it isn’t. The biggest constraint is venting path and the HOA’s approved termination — both solvable.

**What’s the lead time on a high-end linear unit?**
Domestic linears (Heat & Glo, Montigo): three to six weeks. European linears (Ortal, Stuv, Spartherm): eight to fourteen weeks. We order the moment you sign so the cabinet is in the warehouse when framing is complete.

**Will the fireplace heat the room or is it just decorative?**
Modern linear gas units throw between 25,000 and 45,000 BTU — enough to heat a 600-square-foot great room comfortably on the lowest Dallas January night. Most Knox-Henderson owners run them on flame-only mode 80% of the time and bring heat up for ambiance during dinner parties.

**Do I need a permit if I’m just swapping one gas unit for another?**
Yes, in Dallas, any gas appliance swap requires a permit and inspection. We pull and close every permit on every job.

**How disruptive is install day in a high-rise condo?**
Less than you’d think. We use building service elevators, lay protective film on hardwood floors, contain dust at the work zone, and clean before we leave. Most installs are one to three days, with the building never aware we were there beyond the elevator log.
