Yes, a bungalow fits perfectly on it. Unfortunately, I can't open the attachments without WLAN, but I see 's photo. Even if it was once joined together, I would only build on the right side of the plan so that the plots can be separated again later if necessary. Even if only symbolically for the child. Do you have measurements? I would orient myself along the northern property boundary and build parallel to it. This creates an interesting area in the south that opens to the west. That would be my first impression. Of course, you can place the garage as you have drawn it. Draw the whole area or the eastern piece of land and try playing around with rectangles there.
