Home Additions FAQ for Kirkland Homeowners
How do you match the addition to my existing home?
We carefully study your home’s architectural style, materials, and proportions. We source matching or complementary roofing, siding, windows, and trim so guests never know where the original ends and the addition begins.
What does a home addition cost in Seattle?
Home additions in Seattle typically range from $250-$500 per square foot. A simple room addition might cost $80,000-$150,000, while a master suite addition runs $150,000-$300,000+. Second story additions start around $250,000.
How long does a home addition take?
A bump-out or small room addition might take 2-3 months. A master suite addition typically takes 4-6 months. Second story additions can take 5-8 months. Seattle permitting can add 6-12 weeks.
Will my addition be more energy-efficient than my existing home?
Absolutely. We build every addition to exceed current energy code, often to near-Passive House standards. The new space will likely be the most comfortable, efficient part of your home.
