A fixed-price addition project from our Plano-based DFW team serving Highland Park homeowners, with designers, project leads, and tradespeople who finish on the day they said they would. Eleven years, one promise: your quote is your price.
A home addition in Highland Park typically runs $120,000 to $400,000, and in this market it routinely exceeds that ceiling, because Park Cities additions involve estate-grade materials, custom millwork, and exacting architectural matching. Permits and inspections go through the Town of Highland Park’s Department of Building Inspection, under the Director of Development Services, with digital submittals handled via the Town’s OpenGov system. Every trade on your project, general, electrical, plumbing, and mechanical, must be both licensed by the State of Texas and registered with the Town. The biggest cost driver here is the built-out nature of Highland Park: with no vacant land and strict lot-coverage and zoning standards, additions push upward or into tight rear yards and must match the slate, brick, stone, and detailing of a century-old home, all of which raises engineering, design, and material costs well above a typical suburban add-on. We work on a fixed-price model with a 1-year workmanship warranty. For a line-item look at where the money goes, see our DFW remodel cost guide.
We handle survey, setbacks, engineering, HOA and permits before demolition. If your lot cannot take the footprint, you will hear it at the first walkthrough.
Fixed scope and a written schedule before anyone breaks ground in your yard.
Adding square footage in Highland Park is a different exercise than in a newer DFW suburb. The Town was platted in 1907 by John Armstrong and Hugh Prather, laid out by Wilbur David Cook and George Kessler, and it has been fully built out for decades with roughly 8,500 to 9,000 homes and no vacant land. So a Highland Park addition almost always means expanding an existing 1910s-1920s estate or a Tudor, Mediterranean, Georgian, or Colonial Revival home on a finite lot, not building on open ground. That changes everything: matching original brick, slate, stone, and steel-casement details; respecting the Town’s strict zoning and architectural standards; and threading a second-story or rear addition into a mature, tree-lined street. UHS Remodeling has delivered projects across DFW since 2014, and we design additions that read as if they were always part of the house.
We build home additions across Highland Park, including Willow Bend, Legacy West, Deerfield, Hunters Glen, Russell Creek, and West Highland Park Estates.
Site walk, scope (bedroom, master wing, second story), zoning + setback review, budget alignment.
Architectural drawings, structural engineer review, exterior match planning, MEP routing.
City of Highland Park plan review, HOA architectural committee, energy code compliance. Average 3-5 weeks.
Foundation, framing, roof tie-in, MEP rough-in, insulation, drywall, finish-out. 12-22 weeks per scope.
Final inspection, punch list, certificate of occupancy filing, 1-year warranty active.
New slab and framing tied into the existing structure.
Matched brick and tinted mortar at the old-to-new seam.
Design and structural engineering run first, and city plan review plus the HOA architectural committee average three to five weeks before anyone breaks ground.
“An addition in Highland Park is half permits, half craft. We pre-meet with the city’s plan review before drawings are stamped — that’s why our additions break ground 6 weeks after contract, not 14.”

Which one is right depends on your lot line, your slab and your roof — not on a catalog.
Renderings from our design studies — the finished Highland Park projects are above.
Ranges include foundation, framing, roof, systems and finishes — everything but landscaping.
All ranges include architectural drawings, engineering, materials, labor, permits, foundation, framing, MEP, finishes, and 1-year warranty. Sourced against NARI Cost vs. Value 2025 and your city building code requirements.
Single-room addition (250-450 sqft): bedroom, office, sunroom. Exterior match, standard finishes, full MEP.
Master wing or large family room (450-800 sqft): primary suite + bath, formal dining add-on, or great room expansion.
Second story or full custom (800+ sqft): structural foundation work, full second floor, matched exterior, custom millwork.
Additions live or die on setbacks, easements and lot coverage — and every DFW city writes those rules differently. We have permitted additions across Highland Park and the neighboring cities, which means we can tell you in one visit whether the footprint you want is legal on your lot.
We deliver home addition across the northern DFW suburbs. See our home addition in Frisco, Allen, and McKinney.

Most Highland Park additions run $120,000 to $400,000, and they frequently exceed that because this is the most expensive residential market in Texas. Estate-grade materials, matching century-old architecture, and the engineering needed for second-story or tight rear additions all push costs higher than a typical suburban add-on. UHS quotes every project on a fixed-price basis.
Yes. Highland Park has no vacant land, so additions expand the home you already own rather than build on open ground. That usually means a second-story addition, a rear addition into the existing yard, or a reconfiguration that stays within the Town’s lot-coverage, zoning, and architectural standards. We design within those limits and match the original brick, stone, and rooflines so the new space looks original.
The Town of Highland Park’s Department of Building Inspection, under the Director of Development Services, issues addition permits, with digital submittals through the Town’s OpenGov system. All trades, general, electrical, plumbing, and mechanical, must be licensed by the State of Texas and registered with the Town before work begins.
A home addition in Highland Park typically ranges from $120,000 to $400,000, depending on size, foundation, and whether it is single- or multi-story.
Single-room additions take 16–28 weeks. Multi-room wing additions run 10–16 months. Second-story and estate-scale additions take 14–28 months. Add 3–6 months for design, engineering, and permitting.
Yes, subject to height, setback, and lot coverage limits. Architectural review, structural engineering, and sometimes neighbor notification are required. Not every foundation is adequate for a second-story load — we check feasibility early.
Yes, subject to lot size, setbacks, and lot coverage. Guest houses (800–1,800 sq ft), pool houses (400–1,000 sq ft), and garages with living above are common. Each requires its own permit.
We source original or visually identical brick, stone, slate, windows, and trim. For Tudor stucco, we work with plaster artisans. Matching materials may add 6–12 weeks to procurement.
Yes. The Town has architectural review requirements for additions affecting exterior appearance, height, lot coverage, or massing. UHS handles the full submission and review cycle.
Usually yes, especially for detached and rear additions. For second-story additions, most homeowners relocate for 6–14 weeks during structural and weatherization phases.
Yes. Every addition is engineered by a licensed Texas structural engineer. We handle full foundation scope and all structural framing including steel beams, load transfers, and second-story floor systems.
Yes. Highland Park strongly discourages additions that clash with the original architecture. Mismatched additions reduce home value. We design in the same architectural language — Tudor, Colonial, Mediterranean, or modern.

North Texas sits on highly expansive clay soil that swells during wet months and shrinks during summer droughts, which can shift foundations by several inches over seasonal cycles. That is why every room addition we build in Highland Park and Frisco starts with a foundation plan designed by a licensed structural engineer for the specific soil conditions of the lot. Typical solutions include steel-reinforced slab foundations and concrete piers that reach below the active soil zone, so the new addition moves with the original home instead of pulling away from it. Skipping this step is the most common cause of cracked brick, sticking doors, and separated rooflines in DFW additions.
Tell us what you need more of and we’ll walk the lot, check the setbacks, and give you an honest budget range before you commit to anything.
