How much does it cost to dig existing detached double car garage further down about 4.5 feet and to level along the slope out to the driveway?
My driveway has a slope. So to level along the driway to inside the garage.
Please kindly advice. Thanks
You can assume your garage has foundations. The foundations were designed to hold a slab at the level it's at now. You would have to do some extensive structural work to achieve a deeper garage. You may be better off building a new garage.
With the information you've given, I would recommend a budget of $100,000.
Good luck with your project.
