well, that really depends on your starting point and the level of finishes you select. our firm tends to work on project that are custom builds. to give you a rough idea we build anywhere from $350/sqft to $600/sqft again depending on the level of finishes and details. The best approach is to develop your team, ie builder, architect, designer, engineer and flush out your plans as detailed as possible. this will give you your accurate pricing. hope this helps.
