Home Additions in Highland Park, TX

A Highland Park home addition is one of the most architecturally sensitive construction projects in North Texas. Every addition inside the Town of Highland Park is built on a home valued at $2.8M–$25M+, reviewed under strict setback and height restrictions, and executed on lots where every square inch matters. The new addition must look as if it has always been part of the home — the same brick or stone, the same roof pitch, the same window profiles, the same crown moldings and ceiling details. Done right, a Highland Park addition adds livability and significant property value without disturbing the architectural integrity of the original structure.

UHS Remodeling handles every phase of Highland Park addition projects: feasibility studies, architect and structural engineer coordination, Town of Highland Park permitting and architectural review, excavation and foundation work, framing and structural, envelope matching (brick, stone, stucco, roofing), full interior finish, integration with existing HVAC/electrical/plumbing systems, and final punch-list. Every project is delivered with one dedicated W-2 crew, fixed-price contracts with full line-item transparency, daily photo updates, and a written 3-year workmanship warranty.

Highland Park Home Additions — 3 Project Tiers

Highland Park is an exclusively upper-tier market. Every addition here must meet architectural review standards and match the craftsmanship of $2.8M–$25M+ homes. Here is how our Highland Park addition work breaks down.

Tier 1: Single-Room Addition ($180,000 – $450,000)

This tier covers targeted additions that solve a specific need without reshaping the home. Scope includes: master bedroom expansion, walk-in closet addition, sunroom or screened porch, rear family room, home office addition, mudroom and laundry expansion, dedicated gym or yoga room, or primary bathroom expansion. Typical size: 250–800 square feet. Scope: new foundation (pier-and-beam or slab depending on existing), framing, matching exterior envelope (brick, stone, stucco, roofing), matching window profiles, integration with existing HVAC, electrical, and plumbing, full interior millwork and trim, finishes to match or complement the existing home, and updated insulation. Timeline: 16–28 weeks including permitting.

Tier 2: Multi-Room Wing Addition ($500,000 – $1,200,000)

The core of Highland Park addition work. This tier serves homeowners who want to add a full wing to the home — typically 800–2,000 square feet covering multiple rooms. Common scopes: rear great room + kitchen extension + covered porch; master suite wing (bedroom, bath, dressing room, sitting area); kid or in-law wing (bedroom, bath, playroom, study); formal entertaining wing (bar, wine room, powder room, media). Scope includes everything in Tier 1 plus: structural engineering, possible second-floor impact analysis, tie-in of HVAC zones, new plumbing rough-in, dedicated electrical sub-panel, windows and doors matched to the existing home’s period and profile, full interior finish with custom millwork and built-ins, and coordination with interior designer and landscape architect for flow to outdoor spaces. Timeline: 10–16 months including design and permitting.

Tier 3: Second-Story, Guest House & Estate-Scale Additions ($1,200,000 – $2,500,000+)

The most ambitious Highland Park additions reshape the entire home or the property. Scope includes: full second-story additions over an existing ranch or single-story home (1,500–3,500 sq ft upper level with master suite, additional bedrooms, office, laundry); full detached guest houses (casitas, in-law suites, nanny suites with kitchen, bath, bedroom, living); pool houses and cabanas with full kitchen, bath, lounge, outdoor shower, and changing area; detached garages with living space above (car collector garages with 4–6 bays plus second-level apartment, gym, or studio); basement excavations and lower-level additions (wine cellar, home theater, wellness suite, gym); and extensive outdoor living pavilions with fireplaces, kitchens, pools, and spas. These projects require full architectural and engineering coordination, Town of Highland Park architectural review, and often neighbor notification. Timeline: 14–28 months including design, permitting, and construction.

Highland Park Home Addition Cost Breakdown

Where does the budget actually go on a Highland Park addition? Here is how the total breaks down across the three tiers.

Common Highland Park Addition Types

Every Highland Park property presents different opportunities. Here are the additions we build most often for Highland Park homeowners.

Master Suite Additions & Primary Bedroom Wings

The single most requested Highland Park addition. Original 1920s–1940s Tudor and Colonial homes were rarely designed with the oversized primary suites Highland Park families now expect. We add 600–1,500 sq ft master wings including new primary bedroom, spa bath, dual walk-in closets, dressing area, sitting area, and private outdoor terrace. The addition ties into the existing home through a gallery hallway that maintains circulation and preserves the original floor plan.

Kitchen & Great Room Extensions

The second most requested scope. Most original Highland Park homes have kitchens that are too small and closed off from the rest of the home. We bump out 400–1,200 sq ft to the rear of the home, expanding the kitchen and adding a connected great room, breakfast area, or family room. The new space features oversized islands, walls of glass opening to the yard, and coffered or beamed ceilings matching the rest of the home.

Second-Story Additions Over Single-Story Homes

Highland Park has a significant inventory of single-story ranch and contemporary homes that homeowners want to expand vertically. Second-story additions add 1,500–3,500 sq ft and typically include the new primary suite, additional bedrooms, bathrooms, and sometimes a media or study loft. We engineer the new floor system carefully (steel beams, wall reinforcement, foundation upgrades) and match the exterior envelope (brick, siding, roofing) to the existing home.

Detached Guest Houses, Casitas & Pool Houses

Highland Park lot sizes and setback allowances often permit a detached accessory structure. We build full detached guest houses (800–1,800 sq ft with kitchen, bath, bedroom, living), pool houses and cabanas (400–1,000 sq ft with bath, kitchenette, lounge, outdoor shower), and car-collector garages with living space above (4–6 bay garage plus a second-level gym, studio, or apartment). These structures match the architectural language of the main house.

Outdoor Living Additions & Terraces

The line between interior and outdoor living has blurred in Highland Park. We build covered outdoor living pavilions (400–1,200 sq ft) with outdoor kitchens (Wolf, Lynx, Kalamazoo), fireplaces, built-in lounge and dining, heaters, retractable screens, and integrated automation. Many Highland Park projects also include new pool construction, spas, outdoor showers, and full landscape coordination alongside the hardscape addition.

Highland Park Addition Architectural Review Requirements

The Town of Highland Park enforces stricter architectural standards than surrounding DFW cities. Every addition must pass through the Town’s building department and, depending on the scope, the architectural review committee. Key requirements that affect design:

• Setbacks. Front, side, and rear setbacks are strictly enforced. Certain lots have additional building envelope restrictions based on neighboring structures.
• Height limits. Maximum building height is regulated by zone. Second-story additions and tall roof pitches must be confirmed in design development before construction drawings.
• Lot coverage. Maximum lot coverage (impervious surface) limits how much of your property can be built or paved. Pool decks, driveways, and terraces count toward this limit.
• Exterior material matching. Additions must match the existing home’s exterior envelope (brick, stone, stucco, roof material and profile). Sourcing original brick or slate may add 6–12 weeks to the schedule.
• Roof pitch and line matching. New additions must respect the original roof lines, pitch, and visual massing. This is the most common reason architectural review sends plans back for revision.
• Neighbor notification. Certain addition scopes (second-story, large rear additions) require notification to adjacent property owners before permits are issued.

“We added a 1,400 sq ft master wing plus a 700 sq ft pool cabana to our Highland Park Tudor. UHS matched the original 1928 brick and slate roof perfectly — you genuinely cannot tell where the original home ends and the addition begins. They handled every meeting with the Town and kept the project on the fixed-price contract through 14 months of construction.”
