A primary suite addition in Keller adds 450-700 square feet of new conditioned space — bedroom, spa-grade bath, walk-in closet, sometimes a sitting nook or coffee station. Most Keller additions land in the $250,000 to $450,000 range as of 2026 depending on finish tier, foundation complexity, and roofline tie-in. From first consultation to keys: 8-11 months, of which 16-24 weeks is active construction.

Primary suite additions for Keller, our home town.

Swanson Renovations was founded in Keller in 2007. We know the neighborhoods, the lots, the ARBs, and the exact way the 1995-2010 Keller builds age out of the original primary-suite footprint. Almost every primary suite addition we’ve done in Keller solves the same problem: the original suite was sized for a decade with fewer clothes, smaller baths, and less closet expectation than the homeowners now have.

Adding a new suite is our recommendation when the existing primary is under 400 sq ft, poorly oriented, or too far from where the family actually spends time. The new suite gets sited deliberately (usually off the back or side of the home, sometimes as a second-story addition above an existing single-story wing), sized for today’s expectations, and the original primary becomes a guest room, office, or dressing suite for the kids.

The four Keller neighborhoods we build additions in most.

Marshall Ridge.

Larger lots, room to grow off the back or side. Additions here typically run 550-700 sq ft with a substantial spa bath and a real walk-in closet. ARB review is required for exterior changes.

Old Keller.

Original 1970s-1990s ranches and traditional homes. Additions here have to respect the original architectural character — matching roof pitch, matching exterior materials, correct proportion at the tie-in. No HOA in most of Old Keller, but the town’s Historic Preservation Board reviews some blocks.

Hidden Lakes + Estates at Hidden Lakes.

Newer builds (2005+), most already have generous primaries — additions here are less common. When they happen, they’re usually large scopes: primary suite + adjacent office or media room, or a second-story addition. Estates at Hidden Lakes has active ARB.

What’s included in a Swanson Keller addition contract.

  • Design coordination with your interior designer (or one we introduce). We coordinate the interior finish plan in parallel with the shell design so shell dimensions match interior intent.
  • Architectural drawings. Complete construction documents from our architect partners.
  • ARB submission + City of Keller permits.
  • Foundation. Slab-on-grade typically; pier-and-beam or raised when the site or design requires. Drainage and grading integrated.
  • Framing + roofing. Wood frame, engineered lumber for spans, roof tied into existing home’s rooflines. Roofing matched to the existing home’s material.
  • Exterior finishes. Stucco, stone, brick, or siding — matched to the existing home.
  • Full MEP. New HVAC zone, electrical service extension, plumbing to new bath and any wet-room, gas if needed.
  • Interior finish-out. Insulation, drywall, trim, flooring, cabinetry, tile, fixtures — coordinated with your designer’s spec.
  • Project management. BuilderTrend daily updates, weekly walkthroughs with you and your designer, single point of contact (Nancy).
  • Site protection. Ram-board flooring in the existing home’s traffic corridor to the addition site, zip-wall dust barrier at the tie-in point, daily cleanup.

Frequently asked questions

Why add a primary suite instead of remodeling the existing one?
Two reasons. First, the existing primary is often too small — most Keller homes from 1995-2010 have primaries in the 250-380 sq ft range, which was ample then but feels tight now. Second, the existing primary is often in the wrong place — either too far from where the family actually spends time, or oriented badly for morning light or the lot's best view. Adding new suite square footage lets you site it deliberately, size it right, and convert the original suite to a guest room, office, or media room.
What does a primary suite addition cost in Keller?
Most Keller primary suite additions we build land in the $250,000 to $450,000 range. Budget lever one is size: a compact 450 sq ft addition (bedroom + bath + closet, tight configuration) runs $250-325K. A generous 650-700 sq ft addition with a real spa bath and a walk-in closet sized for both partners runs $375-450K. Budget lever two is finish tier: spa-grade primary baths with steam shower, freestanding tub, integrated cosmetic lighting, custom vanity millwork, heated stone floors push you into the upper band.
How long does a Keller primary suite addition take?
Active construction: 16-24 weeks. Pre-construction (design coordination with your designer, architectural drawings, HOA architectural review where applicable, City of Keller permits, material lead times): 10-14 weeks. From first consultation to keys: 8-11 months typical.
Can we stay in the house during a Keller primary suite addition?
Almost always yes. We're building new square footage onto the home, so the existing primary stays fully habitable until the new one is ready. The two disruptive moments are the foundation dig (a week of loud equipment) and the roofline tie-in (5-7 days of exterior noise). Interior mess in the existing home is minimal because we're not opening its walls — the only interior scope is the small cut where the new suite connects to the existing hallway.
What Keller neighborhoods do you work in?
Our core Keller work is concentrated in Marshall Ridge, Old Keller, Hidden Lakes, and Estates at Hidden Lakes. Additions are common in Hidden Lakes and Marshall Ridge (larger lots, room to grow). Old Keller additions require more attention to the original 1970s-1990s architectural character.
Do you handle HOA architectural review for Keller additions?
For neighborhoods with active ARBs — yes, we draft the submission package as part of the contract (elevations, site plan, materials board, renderings). Marshall Ridge and Estates at Hidden Lakes have active ARBs. Old Keller and much of the older neighborhoods don't. City of Keller permits are required regardless.
Do you provide 3D renderings, or do I need to bring my own drawings?
Yes — every Swanson estimate includes 3D renderings of your addition as part of the design phase, so you can see how the new suite ties into your home before construction starts. If you're working with a designer who needs an extra hand, we also draft floor plans and renderings in-house. If you don't have a designer yet, we can develop the drawings ourselves or introduce you to one we trust.
