Thread: Aproximate size of a underground garage (scetch inside)

I've drawn a style of a garage that I'd like. It's meant as a underground garage built in a elevated terrain so only the opening is "above ground".

Thing is, I'm really lousy with sizes so I have no idea how big this woulb be.

The scetch is as follows. It's made for seven cars and one motorcycle with the two cars on the sides having extra space.
Given the size of a "normal" car and a "normal" bike, how big would this garage be in rough numbres?

Thanks for your help!

90' wide by 45' deep

I'd say 65x35.

Average car is 10 feet long and I'd say 3 cars in length + the extra five feet.

Average car is 5 1/2 feet wide so if I use a ruler and do bad math I get my dimension.

Thanks fellas!

A Fiat 500 is 10 feet long. I'd say the average car is about 15 feet.

If you want that layout and want comfortable space between the cars I'd say 70ft wide and 40ft deep.

In building underground garages one of the biggest issues is the angle of the driveway leading in and out, you dont want cars scraping. Be careful with that.

If you have a property survey with elevations and contours of the lot you are looking to build this I could put together a rough plan showing dimensions, instead of speculating.

EDIT: I did a quick sketch using 19' as an average for vehicle length. Following your design and accounting for some extra room for maneuvering my layout was approx. 110' Across and 60' Deep. Like I said above, I can put together a realistic layout if I have a property survey.
