Garage over 4' drop off

[Stone2700]

Would like to construct a double garage at side of house but after approx. 12' of level ground there is a straight drop off down 4' that the back of the garage would need to be built over. Is that even possible?

All it takes is money. Bueller? Bueller? http://tachboard.com/ferris-buellers-friends-garage/

Backfill the 4' with dirt and compact then procede with building.

That's funny. But he is right.

Site prep sometimes equals money.

Location might help.

Not sure what your up against. Retaining wall or fill dirt. Possibly a two story garage like mitt Romney with an elevator for the car.

I doubt you'll need anything so extreme, but this thread shows what can be done. http://www.garagejournal.com/forum/showthread.php?t=279231. One of my favs, right up there with the Concrete Underground.

Without a doubt, their engineering is great but the best part is their hats.

A 4' fill area is not that big of a problem in my area. The locals will often bring in medium sized boulders packed close together, cover them with soil and thus have a minimum of settling when building over the fill area. Or, I imagine a 4' retaining wall can be built of cinder block and that be filled with soil as well. Always more than on way to solve a situation.

There is a retaining wall before the drop. The rest of the yard is a down 4' lower.

As always, photos of the area in question required.

Pour a dropped footing at the low grade area. Then pour a stem wall foundation with a slab ledge and beam pockets on the interior. Height of stem wall varies based on grade. Backfill with loose fill, pour a structural slab with grade beams, and move on. Done every day of the week here. Several times a day in fact.

Make sure the wall is reinforced with rebar and the cores filled if you are using block. There was a long thread on here a hear or so ago about a foundation wall that was not reinforced and cores filled and the whole thing went down the hill when they were trying to fill. This might be a place an engineer should be used. But just stacked mason units will not by themselves be enough.

Shouldn't be a problem. I did that for part of mine where it dropped off a few feet. Lots of big rocks covered by a layer of compacted dirt. It took a day of work work with an excavator and cost me $1000.

The back of my garage is on a hill and footers with wall measure 8ft at the lowest point. Will post picks tomorrow
