Survey and soils first
Topography, soils, the water table and where the rock is. What comes out of the ground decides the foundation, and the foundation decides a great deal of the budget.
By-right, before design
Zoning, setbacks, height, coverage and any overlay. We establish the envelope you are allowed to build inside before anybody draws a house that will not fit in it.
Services to the street
Water, sewer or septic, power and gas: what is at the kerb, how far it has to run and who owns the easement it crosses.
