How deep is the lot? the further from the curb you build, the gentler the driveway slope can be. You could build an attached garage to the side. A dome is a better choice for a stilt mounted home due to it's shell strength. Your covered outdoor area could be under the dome floor, between the stilts. Freebeard?
I see West, (evening Sun) facing pretty much down the street, and South facing the Cul D' Sac and Sun blocking two story homes. Maybe your Grandparents would sell you a home lot to build on until you inherit the whole.
