Building on a slope usually requires more time, planning, engineering, and site preparation than building on a flat lot. In many cases, the cost of building on a slope can be around 20–30% higher, depending on the steepness of the site, soil conditions, excavation needs, retaining walls, foundation type, septic system, drainage solutions, home size, access, and selected finishes.
As a slope home builder, we evaluate the property early and help define a realistic budget for a custom modern home designed around the site.
