03 · What we build

Types of room additions.

Room & Bedroom Additions

A new bedroom, office, or den on a fresh foundation — matched to the existing ceiling height, flooring, and trim so it never reads as an afterthought.

Primary Suite Additions

A new owner’s retreat with bedroom, walk-in closet, and spa bath — often the single highest-impact addition for both daily living and resale.

Bump-Out Additions

Extending a room two to fifteen feet to enlarge a kitchen, bath, or dining area. Often cantilevered, which keeps cost and schedule down.

Sunrooms & Four-Season Rooms

A glass-forward room tied into your HVAC so it lives all year — and one of the strongest resale returns of any addition type in DFW.

In-Law & Guest Suites

A private suite — bedroom, full bath, often a kitchenette or separate entrance — designed for accessibility and aging in place when needed.

Second-Story Additions

When the lot can’t grow outward, we build up — engineered and reinforced foundation first — to nearly double living space without losing a foot of yard.

Kitchen & Bath Expansions

More room, not just a new room — part addition, part interior remodeling, reconfigured into the layout the original plan never allowed.

Garage & Attic Conversions

The lowest cost per square foot, because the structure already exists. Proper insulation, egress, climate control, and code-compliant ceiling height.

From the field · Dallas–Fort Worth

“An addition is really a tie-in — new foundation, roofline, and HVAC married to a house that’s been moving for twenty years. We engineer that connection before contract, so the price you sign already accounts for what’s behind the wall.”

What types of room additions does UHS build?

All of them: single-room and bedroom additions, primary-suite additions, bump-outs, sunrooms and four-season rooms, in-law and guest suites, second-story additions, kitchen and bath expansions, and garage and attic conversions. As a design-build team, UHS handles the drawings, structural engineering, permits, and construction.

How much does a room addition cost in DFW?

Full home additions in Dallas–Fort Worth typically run $120,000 to $400,000+, while bump-outs, sunrooms, and garage or attic conversions cost considerably less per square foot. Every UHS project comes with a fixed written price before demolition. See our DFW home addition cost guide for a full breakdown.

How long does a room addition take?

A bump-out or single-room addition usually runs 10–18 weeks of construction; a larger wing 20–28 weeks; a second-story addition 30–48 weeks. Add roughly 4–8 weeks up front for design, permitting, and HOA approval before construction starts.

Will the addition match my existing home’s exterior?

Yes. We match roofline angles, brick or siding type, window style, fascia, soffit, and trim profiles, and source matching brick where needed. The goal is an addition that looks like it was built with the original home.

Which room addition adds the most resale value?

In DFW, sunrooms and four-season rooms and primary-suite additions tend to return the most, followed by second-story additions. Returns are capped by the neighborhood resale ceiling — in an area where top-of-market homes sell for $600,000, a $250,000 addition will not return 100%.

Can I live in my home during construction?

For most ground-floor additions, yes. The new construction happens outside the existing home, and the “break-through” that connects it is usually a one-to-two-week phase. Second-story additions are the exception — homes are typically unlivable during the three-to-six-week roof tear-off and framing phase.

Do you handle permits and HOA approval?

Yes. We prepare the full permit and HOA packet — elevations, site plan, materials list, color samples — submit it on your behalf, and manage every inspection through final sign-off.

Which DFW cities do you serve for additions?

UHS builds additions across 20+ Dallas–Fort Worth communities including Plano, Frisco, McKinney, Allen, Prosper, Dallas, Richardson, Carrollton, The Colony, Little Elm, Highland Park, University Park, Addison, Farmers Branch, Flower Mound, Garland, Rowlett, Sachse, Rockwall, Wylie, and Murphy.
