About This Service
Home Additions — What's Included
When moving isn't an option and your family needs more space, a well-designed home addition is one of the smartest investments you can make. We handle additions ranging from bump-outs and room extensions to full second-story additions — all engineered to blend seamlessly with your existing home.
Common Challenges We Solve
- Seattle real estate prices making a move prohibitively expensive
- Cramped living conditions without room for in-law or guest space
- Lack of home office in the work-from-home era
- Additions that look bolted-on rather than architecturally integrated
- Permit complexity and neighborhood setback restrictions
How We Address Them
- Architectural design coordination to match existing home style
- Structural engineering integration with existing foundation and framing
- Permit management through Seattle DCI and county offices
- Exterior matching: siding, roofline, window style, trim detail
- Interior integration: flooring transitions, ceiling heights, HVAC extension
