A University Park home addition is one of the most architecturally sensitive construction projects in North Texas. Every addition inside the City of University Park is built on a home valued at $1.5M–$10M+, reviewed under strict setback and height restrictions, and executed on lots where every square foot of lot coverage matters. The new addition must look as if it has always been part of the home — the same brick or stucco, the same roof pitch, the same window profiles, the same crown moldings and ceiling details. Done right, a University Park addition adds livability and significant property value without disturbing the architectural integrity of the original structure.
UHS Remodeling handles every phase of University Park addition projects: feasibility studies, architect and structural engineer coordination, City of University Park permitting, 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.
University Park is an upper-tier market. Every addition here must meet architectural review standards and match the craftsmanship of $1.5M–$10M+ homes. Here is how our University Park addition work breaks down.
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: 14–26 weeks including permitting.

The core of University Park addition work. This tier serves homeowners who want to add a full wing to the home — typically 800–1,800 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: 9–14 months including design and permitting.

The most ambitious University Park additions reshape the entire home or the property. Scope includes: full second-story additions over an existing ranch or single-story home (1,200–3,000 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, and changing area; detached garages with living space above (car collector garages with 3–5 bays plus second-level apartment, gym, or studio); basement excavations and lower-level additions (wine cellar, home theater, wellness suite, gym); and outdoor living pavilions with fireplaces, kitchens, pools, and spas. These projects require full architectural and engineering coordination and City of University Park permitting. Timeline: 12–24 months including design, permitting, and construction.

Every University Park property presents different opportunities. Here are the additions we build most often for University Park homeowners.
The single most requested University Park addition. Original 1920s–1940s Tudor and Colonial homes were rarely designed with the oversized primary suites University Park families now expect. We add 500–1,200 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.
The second most requested scope. Most original University Park homes have kitchens that are too small and closed off from the rest of the home. We bump out 400–1,000 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.
University Park has a significant inventory of single-story ranch and contemporary homes that homeowners want to expand vertically. Second-story additions add 1,200–3,000 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 to the existing home.
University Park lot sizes and setback allowances often permit a detached accessory structure. We build full detached guest houses (600–1,500 sq ft with kitchen, bath, bedroom, living), pool houses and cabanas (300–800 sq ft with bath, kitchenette, lounge), and car-collector garages with living space above (3–5 bay garage plus a second-level gym, studio, or apartment). These structures match the architectural language of the main house.
The line between interior and outdoor living has blurred in University Park. We build covered outdoor living pavilions (300–1,000 sq ft) with outdoor kitchens, fireplaces, built-in lounge and dining, heaters, retractable screens, and integrated automation. Many University Park projects also include new pool construction, spas, outdoor showers, and full landscape coordination alongside the hardscape addition.
The City of University Park enforces stricter architectural standards than surrounding DFW cities. Every addition must pass through the city’s building department and, depending on the scope, architectural review. Key requirements that affect design:
UHS Remodeling has walked the City of University Park permitting process dozens of times and maintains working relationships with the building officials. We handle the entire submission, review, revision, and inspection cycle on behalf of our clients.
“We added a 1,100 sq ft master wing plus a 550 sq ft rear kitchen extension to our University Park Tudor. UHS matched the original 1932 brick and slate roof perfectly — you cannot tell where the original home ends and the addition begins. They handled every meeting with the city and kept the project on the fixed-price contract through 11 months of construction.”
