INTRODUCTION - DIAGNOSIS

Now that I can post pictures let me tell you about my car hole.

OVERVIEW AND DIMENSIONS

If you're squinting a little, or maybe suffering a mild concussion, I've got a two bay garage (13 x 28 and 10 x 22, respectively) built into the side of an incline with a patio on top (16 x 22 over the narrower section and 28 x 25 over larger section). Behind the bays are two separate storage areas (both roughly 7 x 13)--rumor is they were changing rooms back when a gigantic above-ground metal pool came off the patio (seller had it removed when they bought the house in the early aughts). Behind those rooms is a stairwell from the patio to the lawn. Stone retaining walls sprout out from the front and back for the surrounding land.

Materials appear to be stone, steel, concrete, and cinder blocks. Little wood is involved (or at least left), which I thought I read on some forum was getting expensive...

CONDITION

Exterior - formerly under assault from various trees, plants, and other greenery. Vines were literally coaxed to grow onto, up, and around the building and patio. I imagine the immediate previous owner, given the chance, would've reclassified the building as some kind of art installation. Pieces of the outer wall and window are damaged, possibly from vandalism (damn those rowdy teens!), and need TLC or outright replacement.

Interior - oh, man. Water gets in when it rains, mostly tracking along the overhead beams from the wall built against the dirt, turning the bays (smaller one in particular) into giant humidifiers. This has, as you would expect, caused the little wood remaining to rot, the walls to peel, and the remaining metal to rust real nice. Despite having (mostly) functional bay doors, I now keep them open 24/7 to keep tools and equipment dry. I'm sure my neighbors love that. Otherwise the building seems structurally sound.

At least two doors inside were eventually closed off with cinder blocks, further sealing in the humidity (one leading outside and one to the changing room). There's space for a window between the former changing rooms, but nothing other than the doors going outside from these rooms. The door frames are shot but the side rooms are at least still water proof. There is dim illumination from the block windows in the larger bay.

There used to be electric service from the house, though I couldn't tell you how much or for how long. The original section of the house is super old (1780s) and the addition came in the 1970s, and I'm wondering if the garage didn't come about some time prior the addition.

VISION

Somebody clearly had grand plans for this garage when they built it, which I want to restore and expand upon without breaking the bank (full disclosure: I am not much of a craftsman, so though I'm willing to learn and to do a lot of manual labor this will be largely contractor work).

Most of the garages I've seen here are like palaces, and you have my respect for building and maintaining such impressive spaces. In terms of my garage I'm a simple man--I want to do things right but definitely don't need to "HGTV" what amounts to a bunker. Having a dry, well-lit small work area and the ability to garage vehicles and tools (mostly landscaping) would be amazing. I'm also looking to future-proof my car hole with enough service to charge an electric truck (they're coming!) without worrying about water seeping in and ruining everything.

As far as the electric is concerned, I can see where the old conduit exits my crawlspace bound for the garage and I'm confident I can at least do the trenching myself.

QUESTIONS

Phase I of the renovation--where I tear down and root out all the trees, vines, and bushes growing around it, is just about complete. I'm asking for your frank and friendly analysis here as I look toward the future. Below are my initial questions:

1. How old do you think the original electric is, based on the pictures?
2. If you were to blindfold yourself and shoot from the hip, how much do you think it would cost to get this place decent again? Given the nature of the design I am NOT looking to expand the rooms here, just to reclaim and repair. Feel free to get as granular or broad as you want. Reckless speculation is encouraged and any "minimum" and "reach" numbers are welcome!
3. Dealing with the water seems like the top priority, which I assume means digging out the wall built into the incline and getting it fixed up (runoff from the patio roof, rather than straight leakage from the top, seems to be the main culprit). What would you do to keep the water out?
4. If this was your car hole, what potential do you see? What would be your priority?

Interesting "car hole" you got there. Reminds me of a rotting WW2 era bunker somewhere in Europe. I've got no advice to offer, but I'll be watching to see what you do with it.

Great bones! Love the roof patio. Once you get it cleaned out and some surfaces painted it will look completely different. Only suggestion: Don't scrimp on lighting and outlets.

It's definitely a good place for rotting right now!

Thanks! I will take that to heart. We have 200 amp coming into our home already and I am considering going to 400 to have lots to work with outside the house (really, though, I'd only start getting close with two electric cars charging simultaneously and...currently I have none. So, yeah.

KEErist, is that roof 1ft of concrete??


I love it! I would investigate the possibility of digging a 2ft wide trench around the side buried in the dirt, then install drain tile, gravel etc along with waterproofing membrane or *something* on the exterior of the walls, then back fill.


Electrical service appears to pre-date the invention of the candle so that would all be getting replaced.
Open up the bricked up doors, fix the windows & buggered woodwork etc
Remove/harvest the row of potato's growing across the roof...



Lot's of potential.. especially when it comes to spending money.

Well, that is certainly different.

Wiring looks like 70's-80's to me. From the pictures, and my admittedly low standards, I think I could get that fairly respectable for sub-$2000 range. That's with me doing all of the manual labor and a ton of cleaning....pressure washer is gonna get a workout.

That seam in the patio with the 'taters growing in it concerns me. Sure looks like a prime point of water intrusion. With that in mind, I am thinking a home-brewed roof membrane is in store. Perhaps a Pond Liner would be more affordable than a roof membrane? Seriously, I often substitute similar products across different applications to save lots of money.

And a trench with wall sealant, tile and gravel is an excellent idea for that earthen-banked back wall area.

Get that moisture issue solved and that will be a darn neat car hole. Should be nice and cool too, and fairly warm in winter, depending on which way faces south-west.

Subscribing!

cool place
I agree on the digging & waterproofing , drain tile etc. line the outside of the walls with delta wrap or equivalent , find a membrane to put over the patio floor, or build a large storage shed on top & a peak roof in order to stop water from coming into the lower sections ( 2 story garage /storage)
electrical has nothing worth saving . run a new service to the garage from the house .
400 amp to the house? that's a huge service . are you sure you need that much? 200 is a lot , in most cases, IMO

Cool place. My suggestion for step 1 is to clean it out entirely. Everything that's loose gets taken out. Then you can see what the existing structure is like. You will be able to see the wet spots and when you bring a contractor in he will also be able to have a good look at things.

Take your time. Enjoy the process as much as possible. When it gets frustrating take a break.

That's awesome, I love spaces like that. Rip out and start over with the electric, I haven't seen screw in fuses since I was a child.
I agree with above, clean out everything, including walls and ceiling. Water intrusion will show pretty quickly.

Congratulations! Your place looks like it has a lot of potential. The electric box worries me because of the amount of rust. In the early 1970's I rewired a house with that type of 2-fuse entry box that dated to the 1920's, changing over to circuit breakers. Yours, due to the conduit and type of wiring is closer to the 70's than the 20's. I think your number one priority has to be eliminating the cause of all that rust. Then redo the electric. How many square feet is the place?

You hooked me with “car hole” and landed me with pics of unique garage architecture. The fact that it’s been neglected to the point of becoming urban archaeology just makes this build sweeter.

I love buying houses that are similar - beautiful but thoroughly neglected. Wash that mess, give it a cost of white masonry paint inside and out, rip out and redo the electrical, and I think you’ll be in awesome shape for a few grand. The big concern for me would be fixing any roof and water leaks, but that looks like more labor than dollars spent at this point. Keep us posted!

That roof looks like it will need some sort of membrane to waterproof it and then build a deck on top of it. Quite the project you have there. Be prepared to throw a lot of money at it just to get it dried in.

While there is definitely a cool factor (pardon the obvious bias for partially buried concrete garages), it also looks like a lot of time and money to make it into usable space.

I'd start with a comprehensive structural evaluation. Assuming any shortcomings can be addressed without breaking the bank, I'd move on to making it watertight. Once those two items are addressed you can move on to architectural and utility issues.

There is a ton of potential there. I wish you the absolute best of luck and will be watching in the hope you realize it. Thanks for sharing and please keep us up to date.

Well l the electrical box....is that the ..?..sub panel I assume? That will need to be sent to I U then the trash dept. or the morgue. If it’s all in conduit, I’d evaluate the condition of the wires...pull in new if they are questionable.
