We have shared problems.
I met with my architect Tuesday of this week to rebuild the existing three car 900 sf garage to a three story 8 car garage with one floor being below grade gameroom, wine cellar, and bomb shelter. Middle floor at grade is for trucks, motorcycles and bicycles, top floor pinballs and an ADU for future skilled nurse (if we live long enough, I will want this to avoid long term care outsourced at all costs), with the basement having a full spread of pinballs. Elevator with standby generator is also planned.
Typical Arizona building materials of two by fours, chicken wire, Styrofoam and stucco are replaced with 12-inch thick reinforced concrete.... bunker style. No, not Archie Bunker...... Never moving again!!!
