Why Katy Homeowners Choose IAS for Room Additions
IAS Boutique Remodeling designs and builds room additions for homeowners across Katy, TX — from established homes in Cinco Ranch and Grand Lakes to newer construction in Cane Island. Whether the goal is a primary-suite addition, a second-story expansion that uses the existing footprint, an in-law or guest suite for a multigenerational household, a single-room addition, or a garage conversion, we approach each addition as part of the home rather than a bolt-on. That means coordinating the structural, foundation, electrical, plumbing, and HVAC work together with the architectural design so the new space integrates cleanly with what's already there and the exterior reads as original to the home. As a boutique remodeler we take on a limited number of projects at a time, so your Katy addition gets owner-led attention from the first consultation through the final walkthrough.
- Primary-suite, single-room, in-law, and second-story additions tailored to your home
- Garage conversions and ADU-style additions where the floor plan and lot allow
- Structural, foundation, electrical, plumbing, and HVAC coordinated with the design
- Exterior matching — siding, roofline, and trim — so the addition reads as original
- HOA architectural review coordinated across Cinco Ranch, Grand Lakes, and Firethorne
- Owner-led from consultation to walkthrough, and fully insured throughout construction

Frequently Asked Questions
Do you build room additions in Katy?
Yes. IAS Boutique Remodeling takes on additions throughout the Katy area, including Cinco Ranch, Grand Lakes, Cane Island, Seven Meadows, and Firethorne. If you're not sure whether we cover your community, just ask when you reach out.
Do you handle permitting for a Katy room addition?
Yes. Additions typically require more permitting than interior remodels — structural, foundation, electrical, plumbing, and any roofline changes — and Katy spans Harris, Fort Bend, and Waller counties, so we confirm the correct jurisdiction for your address. Additions also involve exterior changes that need HOA architectural review across Katy's master-planned communities, which we coordinate alongside the permits.
What makes IAS different for a Katy room addition?
We're a boutique remodeler by design — a limited number of projects at a time, direct contact with ownership through every phase, and an addition designed specifically for your home rather than a stock package. We coordinate structural and architectural work together so the result integrates with the existing home, and we're fully insured throughout construction.
How do Katy HOAs review room additions specifically?
Because additions change the exterior, HOA architectural review committees in Cinco Ranch, Grand Lakes, and other Katy communities apply more scrutiny to them than to interior remodels — typically reviewing materials, siding, rooflines, height, and how the addition reads from the street. We prepare submittals with that review in mind and design the exterior to fit the community so approvals stay on track.
