For example:- Architect/drawing fees- Engineering fees- Site clearing- Demolition/removal- Permits- Site preparation- UtilitiesSo, you'll have to get familiar with those facets of building as well, and you'll have to get a reasonable idea of what those things will cost you.2.

They will not be in a closet but may be separated by a 4 feet wall on the side.The reason I am asking is that there are already all connections available if I keep the washer/dryer location same but then it is in the master bath.The alternate design is to move washer/dryer to a side, in a closet and be totally separated with master bath but then it will cost more as I will have to pay for extra plumbing/electrical and vent.any ideas?

I do not have the 20k to 40k for the extras they are asking. 

If you really just want to have something paid off you can put extra principle down at your discretion. 

The addendum is for extra credit to the buyer for paying extra but strictly optional.
