Room Additions in Katy, TX

Expand Your Living Space with Seamless Home Additions

Custom Additions Designed for Katy Homes

As a leading room additions contractor in Katy, TX, we design and build new spaces that feel like they’ve always been part of your home. From a master suite in Cinco Ranch with backyard access, to a bright home office in Grand Lakes, we create additions that match your style, your needs, and your neighborhood’s character.

Our process includes structural integration, finish matching, and climate-conscious construction — so your addition looks flawless and performs beautifully for decades.

When You Need More Space — Without Moving

• New bedrooms for a growing family
• Expanded kitchens for entertaining
• Private in-law suites with separate entrances
• Sunrooms and enclosed patios for year-round enjoyment
• Second-story additions for more square footage without losing yard space

Local Expertise for Katy’s Neighborhoods

Cinco Ranch – Large lots often allow for single-story expansions without sacrificing outdoor space.
Grand Lakes – Perfect for adding home offices or hobby rooms above existing garages.
Kelliwood – Architectural style preservation is key when matching brick and rooflines.
Firethorne – Newer construction often requires HOA pre-approval for any external changes.
Katy Heights – Historic charm means extra care to maintain period-appropriate details.

Our Attention to Detail Shows in Every Addition

From matching existing hardwood flooring to blending brick patterns and roof pitches, we make sure your new space doesn’t just attach — it belongs.

Featured Katy Project: Master Suite Retreat

Before: The family loved their home but needed more privacy and a true retreat space.
After: We added a master suite with:

• Walk-in closet featuring custom built-ins
• Spa-style bathroom with soaking tub and dual vanities
• Private covered patio access
• Soundproof insulation for maximum comfort

“You’d never know the addition wasn’t part of the original house. IAS Boutique Remodeling made the transition completely seamless.” — Sarah & David L., Cinco Ranch

Why This Project Stood Out

This addition blended indoor and outdoor living with a patio connection — a feature many Katy homeowners request to take advantage of the mild winters.
