If I must, I would provide a carspace/carport in the front lawn of your main property for the house and I would leave the driveway to be fully accessed by the granny flat with a carport in the back for them
Remember though, will the return you get from adding a extra carspace (thousands) be worth it?
Whilst on the topic, I remember during my first granny flat build, I spent a lot of energy and most importantly time in obsessing over all the fine details of the granny flat like carspace arrangements when at the end of it all will probably make very little difference in the returns, which at the end of the day, is really all that matters as an investment. This obsession ultimately led to a much longer build time which cost me significantly more in not having the bloody thing up and ready to produce an income - remember to keep things cheap and simple and use logic rather than emotions!
In a current granny flat I have, the tenant who pays me more rent will have the one carspace on the property and the other gets to park on the road
