if you put a road in from kings you are going to get about 10 lots backing onto the existing homes on dean. that will have park view from their front lawns. so those lots will sell well but likely upset the dean residents that like backing onto a park.
im not sure there are good options here. without putting a road into it you’ll get less lots fronting kings.
A better option may be a condo lot on Kings. Plenty of other condos/apartments there.
