hi,
i tried to do little modifies on your design
1- i straightened the front put the garage and storage space , as for the solar cells i decided to put it above the garage to have the batteries in the room beside the garage
2- then i put the swimming pool to have some privacy and not be open to road
3- i put some high trees to make between the passage for the entrance to the first floor to act as a fence
4- i changed the ceiling to straight one but i did not change in the interior
