drive way & concrete help.

[Brendan Seals]

I need some help and some ideas how I can change this to keep or bring more value. I don't know if should extend the drive way knocking down that attached small shed that is in the back. The attach garage/small shed you can see in the back is sunk in by the missed up concrete. Plus, how much you think it will all cost for what you think I can do. I wanting to do the less cost as much as possible of course if it can be done. Thanks
