Frequently Asked Questions
Will the addition look like it was always part of the house?
That's the goal. We match the roofline, stucco texture, and color so the addition doesn't look bolted on.
Can you add a workshop area instead of just vehicle space?
Yes, we frame garage additions for workshop, storage, or vehicle use depending on what you need.
