For understanding: why do you fear sitting in the shade at 85? Do you have a building line that requires the house to be at the front by the street? Why not place the house at the top end at the edge of the property and then set the driveway to the carports on the right (east border of the property)? This is done quite frequently. Otherwise, lot 85 is better shaped for me, it is less restrictive. Roughly estimated: 22m - 3m - 3m - 6m -> leaves 10m width for the house, rather less due to building height-dependent setback areas. At 17m, I would have too little flexibility. How tall shall the little house be? Please consider setback areas early on.
