Price: Cost of plans are base upon how many units(4-plexes) are to be built. The more units built, the cheaper the cost per unit will be charged. We have some developments with at least ten units(4-plexes). We will require an engineered plot plan with the layout of units on the property to determine the number of units to be charged for.
