Construction
Home Additions & Expansions in Houston TX
Room additions, second-story builds, garage conversions, and ADUs — engineered, permitted, and built right.
Service Overview
Built for serious residential decisions.
Saadi Construction Group builds home additions and expansions across Greater Houston — room additions, second-story builds, garage conversions, and accessory dwelling units (ADUs). Every addition project includes structural engineering to properly tie the new construction into your existing home, city permit submission, and full construction delivery under one contract.
Home additions are more structurally complex than new construction because new work must integrate with an existing foundation, framing, and MEP system. Getting that tie-in right requires proper structural engineering and experienced framing crews — not a contractor who treats an addition like a standalone box.
Best For

Frequently Asked Questions
Do you handle structural engineering for home additions in Houston?
Yes. Every addition we build includes structural engineering to design the connection between the new structure and your existing home — foundation tie-ins, load bearing modifications, and roof structure changes are all engineered before construction begins.
How much does a room addition cost in Houston TX?
Room additions in Houston typically range from $125 to $275 per square foot depending on scope, finish level, and structural complexity. A 400 sq ft bedroom addition generally runs $50,000–$110,000. Second-story additions and kitchen expansions run higher due to structural and MEP scope. We provide a detailed quote within 5 business days.
Do I need a permit for a home addition in Houston?
Yes. Any structural addition in Houston and surrounding municipalities requires building permits. Saadi Construction Group prepares permit drawings, submits to the appropriate jurisdiction, and manages the review and inspection process — you do not handle any of that yourself.
