With one completed 65 and another in progress. Plus the side projects that pop up. I am getting to the point where my 2 bay attached garage just ain't working out. It seems like my current set up has become more like a jigsaw puzzle than a 2 bay garage. I have to move 3 things out of the way just to get at what I'm really after. For about the last year I have been working the wife over on this plan. Recently she said go get it already. I went within an hour to get some pricing on some pole buildings,( before she changed her mind). Wound up selecting a 24'x40'x10', with 10' sliding door, access door, and window. The lumber and hardware is here. Just waiting on the steel roof and siding. Will be building the shop myself with the help of friends and family.

I am in the same situation, I have my Gold 72 waiting to come inside but I cant leave the Bronze 72 or 69 out plus the DDs sometimes need repairs.

Good luck with your building.

Wish I had the room, I need to leave Jersey

Sounds great!

I really miss the 26 x 36 (with 10 foot walls) that I had in NY. That was a great shop. Now here in Arizona I have only the usual suburban two car garage. So far I'm managing, and there's no way I can have more without moving. It's a tiny lot.

I hope it goes together smoothly and you have a blast with it!

Scott I would reconsider the 24 ft wide. With a work bench in front of the car with the door down to tight to work all the way around the car. Go at least 28 and 30 would be better. My garage is 28 by 30 and bigger is always better but mine works well. My father-in-law has 25 and its to tight.

I am building my frame off 70 in my driveway, 12' x 16' shed in the back ( built more like a small house extension and serves as a warehouse of parts, blast cabinet, assembly area and lawn mower etc. storage ) and an attached 2 car garage. I can build a larger shed / shop in my back but the taxes here in Westchester county, ny are the highest in the country, so that makes doing almost anything larger not cost effective. I may put up a 12 x 20 x 8 pre engineered tent for $400.00 as they have not been taxing them. My next place wherever it is when I retire to Low Taxes, America, I will build a 20' x 40' X 16' h

I'll 2nd the 24' being too narrow. Mine is 26X28X10 and I wish I had gone 2' wider and 4' longer. I centered my O/H door too which was a mistake. If I'd have offset it I would've been able to tuck a car in the corner and have room for 2 more. In-floor heating would've been nice too.

Put floor pots in now. If you have steel around you can make your own but they are not that expensive.

I envy you guys ith enough room to build anything. Ive got a 1 car garage and its packed full of junk and useless stuff. Plus I have to share it with the washer and dryer and big freezer and a big water heater and a....you get the idea. My garage is more like a puzzle than a work area. When I leave Miami, Ill be building the biggest shop I can afford, I would love something like a 36x48 with 12' walls. Ahhhh, one can dream lol

I also agree with going to the wider width. I finally decided on a 30X40X10 and was surprised at how much room gets taken up with two cars, tractor and a mondo snowblower. I am also glad I have two 10' high garage doors. Makes it easier to get things in and out without losing all your heat in the winter.

I am considering another garage also.

I just have to laugh at these "I would build it another 2 ft wider and 4 feet longer" replies. As soon as someone advocates 2 ft wider and 4 feet longer someone else chimes in and wants to add another 4 feet in width and 10 feet in length above the second expanded foot print. If this process continues we will be talking about 100 ft long (4 bays wide) and 30 ft deep. Keep in mind as you throw out these ever expanding numbers....some people live in neighborhoods that don't want an eyesore that ruins the area. People don't want their neighbors building huge warehouse size structures in the back yard and the is a reason for that.

Someone will surely quip "Why not 100 ft long 4 bays wide and 30 feet deep LOL" . The reason why not is to avoid creating an eyesore that detracts not only from the neighbors property value but from the value of the property that the warehouse size garage is placed on. These garages people are advocating will be larger than the house in some cases. If you live on a huge wooded lot ...multi acres heavily forested... well then whatever goes goes. If you live in an area where other homes are within eyesight these enormous "barns" are a luxury of dubiuos value.

I am struggling with what to do as far as dimensions but I will be HAPPY to get 24 x24. It is all a matter of where you are starting from. I am down to a 22 x 30 garage that handles 3 cars (one crosswise on "skates" in front of the other two). It is a PIA getting at that 3rd car plus there is no room for anything else in the garage.

I had a HUGE under the house basement custom framed (special framing with I beams to eliminate some supporting walls ) that accomodated 3 cars, a lawn tractor and a motorcycle leaving a workshop and on open "junk" room. We downsized before the housing crash and losing that underhouse "playspace" makes me think that 24 x 24 of garage space all to myself would be the WIDE OPEN SPACES.

It is all where you are coming from.

I wouldn't build one with less than 12' ceilings. If you ever want a lift you'll be happy for the extra height. Extra width is nice too! A friend has a 40x80 with 16' walls and he needs more room.

My shop is 24X60-two story but IF I had it to do over and know what I know now, I would opt for taller ceilings rather than having an upstairs for junk.

I could only make mine 24' wide because of a main sewer running across my yard and 24' is not deep enough for very much of a work bench in front of normal vehicles, much less a van or extended cab pickup.

Did someone say "woods and land"? 26X30X14' ceiling

yeah, I think you need to make it 150x75x30 with floor and forced air heat, central air, 300 light fixtures, hoists, etc.........at least. You couldn't possibly work in anything smaller. That's the bare minimum. :sad::sad:
I love listening to how ridiculous a lot of these guys are saying how they are sooooo cramped in these big garages. Having worked easily comfortably doing every possible job imaginable in 2 car garages all my life, I just laugh at some of these garage snob posts.
I agree with you Oman.

Thanks...I sorta thought I was gonna get flamed for that. Junk finds a way to fill the space available. If ya can get two cars inside, have a bench in front of the cars and still be able to open the doors on one car (the car ya are working on) the rest is just ...well..... BS.

Living in HOTLANTA the A/C makes sense unless you insulate the S----t outta the building and /or have good flow thru ambeint air ventialtaion. The rest is just well I guess BRAVADO.

Opposite goes for the Northern guys ...Ya gotta have heat in the winter. I know because I lived in the North East for a long time. I had garage heat and worked in awful blizzards while living at the top of a faily big hill. It was sorta neat...working on my car while the rest of the world was freezing /shoveling. I LIKED having the "Man Cave" where I could ignore the snow / cold.

I also had a backup generator that ran the furnace and the therefore the heat for the house if Connecticut Light and Power dropped the ball. Working on the car I could look out the window now and then and watch the snow whistle by the windows.

Same / opposite goes for the Atlanta heat. Nothin like working in that basement garage I had while the outside temp was 93 or 95 and the morning humidity was 96%. I was at a cool DRY 65 / 70 all the time!!! If you can self police your acquisition of "Stuff" you just don't need these Garage Mahal size buildings to have fun.

I know a guy in Connecticut who has a garage that easily can handle 10 cars. 3 on an upper level and 6 or 7 (depending how ya pic em) on a lower HIGH CEILING level. One level is three or four steps lower than the other to accomodate the topography of the lot. It is so full of junk...several non running riding lawn movers, a boat that won't float more than a few minutes...old cars that have NO CHANCE of ever being restored...large entry way light fixtures that belong in the "Gone with the Wind" flick, rust bucket 57 Buick, 29 fiberglas Model T replica, 29 Model T (Phonebooth) sedan, 40 Ford Sedan, 49 Merc, 65 Chevelle.

Only two of those cars run, the rest NEVER will run. JUNK JUNK JUNK...the list goes on and on. Last time I was there the place was a maze of walkway size pathways between the junk. Such a waste. He would say that "Ya cannot have a garage that is too big" along with others of the same mindset.

....I just have to laugh at these "I would build it another 2 ft wider and 4 feet longer" replies. ......

.....I just laugh at some of these garage snob posts.
I agree with you Oman.
Garage snob? Um, I don't think so. I could give a rat's ass if somebody's garage is bigger than mine. What would be really nice is if I could get my Chevelle, my extended cab long box diesel and my wifes car along with everything else inside the garage when it's 40 below.

I built my garage as big as I thought I'd need. I need it bigger. I wish I had somebody advising me before I poured the pad.

As far as flaming, I don't have the time or energy.

That's why you must need a 150x75x30. I need one also. I need to get all my cars, my boat, the cars I am working on, my brothers' cars, my sisters cars, my aunts cars, the neighbors cars, and a 20 ft pile of salt in my garage or else I won't be happy. If the garage snob fits, wear it.

I need a bigger garage and you need a hobby other than this forum.

I need a bigger garage and you need a hobby other than this forum.

My hobby is now feeling sorry for you. Do you hear the miniature violins playing for you?

My garage is 28 by 30 and bigger is always better but mine works well.

Your shop is 840 square feet. Mine will be bigger at 960 square feet. Therefore mine must be better than yours.:D Now actually I think most everyone that builds their shop will almost always wish they would have gone bigger after they build. Also everyones needs and space to build will be different. I have a fairly narrow lot that also has an awesome view out back. There is a beautifull pond ,woods etc. Lots of wildlife at the pond. If I went wider I would lose the veiw. The 10' door will be on the 24' wide end of the building. Work bench will be at the opposite end. I could store 4 Chevelles in there. I know I can't work on 4 Chevelles in that space. Keep in mind I also have the 2 bay attached garage. The wife will be very happy to be able to park in her bay again. Cost for me is also a big consideration. I was able to buy this building outright, no loan. I feel that for just over $6,000 I got one hell of a shop. Of coarse this does not include excavating, electric, or the concrete slab. All of which I hope to do myself. I feel very fortunate to be able to enjoy this hobby of ours.

I didn't notice you had another garage to park in. The reason I said to go wider is to be able to park 3 cars side by side. That's going to be a great shop. Great price too. I'm jealous. Mine's only 732 sq ft. I think I'll burn mine down and start over. ;)

Congrats! Nothing better than a big garage. Although my 28 x 34 isn't quite finished, it's now usable. Much better than my old 12 x 22.

That Low clearance lift is nice. I know that in a few years when Im ready to build my shop on my back acre that Ill be going 30' deep by 40' wide. Flow through doors for ease and ventilation.

Nice garage, I'm drooling over that one. I have a one acre lot that I'm planning to build a garage in the backyard eventually in a subdivision and a lot of neighbors have steel buildings for secondary garages. One guy has this huge beige steel building right on the property line. I would guess 40'x100' with one of those sodium lights that lights up his yard and the next 4 yards in all directions. I'm glad I don't live near him.

Just finished adding on to my garage went from 28 ft x 40 ft to 28 ft x 96 ft. yes added 56 more feet to the building 4 more doors for a total of 6. the new side has 10 foot ceiling height. Plus I have two bays attached to the house. 3200+ sq ft worth of garage
house I live in is 2200 sq ft

Well, I have been busy the last couple weeks. The new shop is starting to take shape. I rented a Bobcat along with a post hole auger. The area is very rocky, yet the auger did a great job of digging the 42" holes. The weather has been great for this time of year. Going to keep pushing forward, trying to beat the harsh weather.

Oh come on Mike. Bigger is better and you know it. Thats why you have 632ci right? So I have to dissagree with Oman. This is a shop related forum so obviously there are going to be differing opinions. I'm building what would be considered a large workshop. My chevelle, well thats a neglected area. To each his own. -MATT

Looking great! Brings back some horrible memories.:D Rain, sleet, mud and deep holes. Do you ever go to http://garageforum.com Check it out and start a build thread. No garage snobs over there.:noway: Just guys helping guys offering up unsolicited advice! Keep up the good work! -MATT

You've got the cruddy work out of the way, now comes the fun! When I put my pole building up a possum fell into one of the holes, being the chump I am, I snared it and set it free to terrorize the neighborhood once again. My brother had his holes dug and the bottom footing poured, called for inspection during a workday. The inspector dissaproved because he wasn't there to provide a ladder to crawl down in the hole to inspect the footing. :confused:

Fixed it for ya. BTW Matt, the car looks fantastic in its new home! That nice BIG shop is exactly what I would build if I had the space.


Oh and I think you should build it as big as you can afford. Dont really care what anyone else says about "garage snobs" or whatever the hell they are talking about. If you have the space, you will find things to fill it up with. One of my favorite shops I have ever seen....and its 72x56. Here is the link.
http://www.garagejournal.com/forum/showthread.php?t=25112

Thanks Will, yeah I've drooled over that shop many times! Garage inside of a garage! Little over the top huh?:D

A little maybe, but it sure is awesome. I would have made the office into a small bedroom and just lived out there instead of in the house lol. Maybe put a pool table anda big flat screen upstairs on the loft and BAM, you have the ultimate Man Cave.

Will if you have any questions feel free to ask. I'm no professional but I do study a lot. (OCD) Can't help it.:D Prozac can only do so much.:cool:

Oh BTW. Where did all the garage snob haters go anyway? Must have realized theres more important things to gripe about in life.:confused:

With a 28 foot deep garage I have room for work benches across the front and still have room to maneuvre an engine hoist. I sure wish that I had gone with the 10 foot ceiling.

Sure will Matt, I appreciate it. Get much more done in there other than wheeling the '65 inside? Did you decide to stick with the rec room deal you were going to do over by the sliding door or did you change plans? You guys are lucky up there. If I were to even think about digging down like you guys did, the water table would fill up the hole faster than I could dig it. Plus, 6" down into the ground around here you hit coral rock and thats like trying to dig into straight rocks...

Well the rec room is 20'x40'. 6x8 bath with crapper and shower. Shop side has urinal and was tub. Also 6x8 utility room for boiler and water heater etc. I'll be updating the build shortly! Enjoy your build. Kind of hard not too! -MATT

Thanks for the words of encouragement. I'm thinking only a car guy would come up with using an engine hoist as a crane to lift trusses into place. I trimmed a 2"x4"x8' to fit into the end of my hoist. I put the hoist in the back of my truck. It worked awesome as a crane.

No, we just realized there's no trying to talk sense to an idiot. Besides, I'm too busy building my 250'x1500'x30' garage. I realized the garage snobs were right and there's no way I could possibly function in any garage smaller than that.

Were you picked on a lot in grade school?

Nice set up Scott! When I bought my barn they set the trusses as long as it was done in 2 hours they didn't charge extra. Having an experienced boom operator was a great help. -MATT

Were you picked on a lot in grade school?

No, I was the kid who laughed at the kids that were getting picked on because they insisted that you had to have the 64 crayon pack and that you couldn't possibly do anything with only the 16 crayon pack. They were crayon snobs......now they are garage snobs. They are still searching for the attention that their mommas didn't give them. LOLOLOL

:D Good comeback.

Some people get off on big garages. Some get off on 600+ cube engines. It's all good.

I sure wish I could turn back the time and have posts like this to read before I built my shop.

There are always a lot of "I wish I had done this or that" things that a person might not think about until reading them in these type threads.

:thumbsup: :beers:

After reading many of these posts I have decided that when I redo mine I am going to rip my existing 2 car off of the house and build a 6 car garage and at the same time increase the size of the master bedroom using the area above the garage. My reasoning is that the power is already at the house, water is there, the bathroom is there, HVAC will be easier to do and my wife will be happy because of the bedroom and bathroom space upstairs.

Since our house is modular I may look at a modular edition / garage.

A friend of mine had a nice setup. His 2 car attached garage stuck out the front of his house a fair bit. He had another 2 car behind it with a single overhead door and a man door between the two. The bedrooms were up above.

:D Good comeback.

Thanks, it's taken a lifetime of hard work to achieve this degree of tactlessness. :)

24 X 40 is a nice size. I did a lot of work in a 24 X 26. built 2 street rods, a 55 chev, painted lots of others. I put the work bench and all shelving on a sidewall and kept the front and back walls clear. I had full floor above and lots of storage room. A 26-30 foot depth would be better, but 24 will work. I eventually added 14 foot to the side for my truck parking and junk I didn't really want in the main garage. When you have nothing or a 1 car garage a 24 X 40 is like the Taj Mahal! I did the 65 Chevelle in a 1 1/2 car garage and a 2 car car port. Wish I had room for even a separate 24X 22 garage!

Getting a little closer to having an enclosed shop. This weather really sucks to work in. I took today off to get more done. Had one of my hot rod buddies here all day helping. This picture is from this evening.

Looking good Scott, I'm trying to finish installing siding on one end of mine to be completley weather proof. Hard to do with either rain for 30 days or single digit temps for 2 weeks. Sure is cold out there.

I built a 30x50 with 12 foot sidewalls. Still isn't enough room. Although I am glad that I went with the 12 foot sidewalls, as I am looking to put a lift in soon. You know it gets to the point that you have enough tools and spare car parts to fill one building by its self!!!!

Hi i am not a garage snob but i have to say i love my 40x60x12 garage,i worked in a barn for years with 3 seprate bays with walls so everytime i had to go to the other bay i had to run if it was raining etc.plus my barn leaked air so all my tools and equip.would get that morning dew and rust my stuff up,that sucked.when i moved i looked at allot homes and most you are right has restrictions. that real estate agent even told me to consider selling off some of my cars!i got rid of her,found a piece of land with no restrictions and built a nice home with room and then built the garage,but i did the garage to match the house,so even though it is big i seem to have neighbors that dont mind they tell me it is nice and i have since had a couple classic car nieghbors over without a hitch. i think build what you can afford,enjoy.

Looking good, Scott. Once you get it buttoned up you can throw a construction heater in there and get some insulation up. The weather won't be a concern anymore. :)

Thanks berner. This is what I was thinking about just this morning, (insulation). I am not looking to maintain a constant temperature in there. It will mainly be used to store my prized toys in . I do have a attached 2 bay heated garage if I need to do work in cold weather. My main concern is moisture, mainly condensation on the metal panels. I understand that even without heating it, it will have condensation to the point that the ceiling will drip on my Chevelle. Well that is as most of you will understand be UNACCEPTABLE ! I'm thinking of the foil/foam/foil type products. There is one that has a white colored inside layer that seems like it might do a decent job. Looking for opinions on what others have done to deal with this situation.

Run 2x4 girts horizontal on the inside,24 inch oc, with a treated board on bottom .Install r-19 or 21 kraft faced horizontal between them for walls then run some 29 gauge white metal liner panel over that.Install the same metal perpendicular to your roof trusses,looks like they are 4 foot centers thats fine .Make an access then you can get up there and lay batts between the trusses.Plastic can be used in between.You'll be all set:yes:

Heres a couple pics of what it would look like when you are done.I have built well over 100 or so pole buildings.Here is a picture of one I recently completed.Looks great,good luck!Did you get hammered with rain today?

John that looks like a great way to go. I'll be calling 84 Lumber to price the 29 gauge metal. Thanks Scott

figure about 3 bucks a lineal foot.About 4 years ago it was half that.Its a great finish,put it up its finished.Reflects light great resist damage anr easy to clean.You will always be able to tell where your framing is to attach shelves etc.Usually I have the elec all surface mounted and run in conduit.You are close enough I can help knock it out if it helps.Usually wrap window jambs with white alum.To really do a nice job you can run a rodent guard trim along bottom.:beers:

I am seriously considering using Prodex Total Insulation to insulate the building.
Check it out here. http://www.insulation4less.com/
It has a good r value, superb moisture barrier, easy to install. Has anyone used or heard anything about this stuff ? The metal panels sweat quite a bit. I'm thinking fiberglass might be prone to get damp, hold the moisture, cause mold, etc. Total cost for my building is $1,200. Also includes the insulation for under the slab, tape, and shipping.

What type of interior finish are you considering over the insulation, or leave it exposed?

I will likely leave it uncovered. I would install it on the girts and purlins. This will give me 1.5" of airspace between the metal and insulation, which the manufacturer says is ideal for maximum performance. If I find myself doing any damage to the insulation, I will put up some sort of protective wall.
