JHD builds ground-up luxury estates throughout San Diego County, including but not limited to Rancho Santa Fe, La Jolla, Del Mar, Encinitas, Carlsbad, and Lake San Marcos.
JHD’s ground-up estate commissions generally begin around $4 million for preconstruction and construction, excluding the homesite. The final investment depends on your homesite, the scale of the estate, and the design and finishes.
