cost of architectural design
A negotiated flat fee can be as low as $700-$1,000 for up to a specified number of hours spent creating a concept design. Or an architect might agree to design a 25x25-foot room addition for $5,000-$10,000, or a 3,000-square-foot custom home for $50,000-$75,000 or more, no matter what the final construction price is.
