Digging beneath the garage floor to accommodate Simulator build?

[ernie900]

Hi everyone

I'm so eager to create a simulator in my garage, with Skytrak most likely. I have a square-ish garage at 17x16.5 ft deep and wide but it is just 8.5ft high and i can't swing properly at that height. My options include number one raising the roof (flat roof to a pitched roof) but I think the neighbours would kick off due to light etc.

I don't know if a second option is feasible which would be to dig beneath the garage floor (concrete) so I had a 3-4ft depression in the garage which I could resurface and place the mat onto with the screen at the end. It could be a comofrtable 12ftx11ft or so in length and width but i don't know if it is doable.

I know i'd have to consider whether anything important runs underneath the garage (eg electrics/pipes).

It might be a bit of work but i imagine it would be cheaper than having a whole new roof put on.

Any thoughts/comments would be appreciated.
Thanks

Some things to consider.

If you dig up your garage, you lose the future use of that space as a garage. That's going to affect the house's resale value no doubt.

Not sure that digging, reinforcing the substrate or footings and doing a concrete pour is in any way going to be cheaper than redoing the roof.
