A basic square addition might run from $150,000–$200,000, while complex custom expansions can reach well into the six-figure range. During your planning session, we provide a detailed estimate specific to your goals.
What's the typical timeline for room additions?Most room additions takes between four to twelve months from start of construction to completion. Larger or more complex additions can extend the timeline. The permit process typically represents a noticeable share of that project length.

Is a room addition the same as a renovation?A home addition adds to your home's total square footage by extending the structure beyond the current walls. A interior update reconfigures your current square footage without increasing total size. Room additions generally involve more complex construction than interior renovation.
