If you've ever received an e-mail from me you'll see this phrase at the bottom of it:
"Good design is a process, not an event."
This is so true, and my own contribution to Quotable Quotes.
My Fees and other expenses - (I am not an engineer. Even thought I've been designing homes for over a decade, I always have my plans reviewed and approved by a licensed Professional Engineer.) Many states require this, Florida is one of them.
My design fees are fairly simple. $45.00/hr. The average 2 story colonial home will take about 35-45 hours ($1575.00 - $2025.00). Time required will very on a number of different factors, such as how well you are prepared, changes, product research, permitting process. I do require a 50% (of the estimated total) deposit.
Other factors to consider: Permit fees, Engineering fees. Engineering fees can run anywhere from $200 for small projects up to $1200 for entire houses.
