Joined the journal a while ago and long overdue to present my labor of love. I moved to the US almost 5 years ago and was mostly accustomed to brick and steel construction. Wooden buildings were something new for me, and after getting over the initial shock of the idea that my house can be eaten by insects, I’ve grown to like the ease, speed, and relative low cost of a stick built house/garage. I bought a fixer-upper 3 years ago, with the idea that this is my practice house and I will learn all the skills to be able to build the true dream house.

When I started on my house, I had none of the skills required. I learnt everything by thoroughly researching, and doing. At home(Belgium), prior to moving to the US I had worked weekends in steel construction, and did a bit of brick-laying on occasion, but I’m actually an aerospace engineer. While that prior experience wasn’t directly applicable, it did teach me one thing: the confidence to tackle a project like this. And that is really all you need, sometimes I’m intimidated by a project I’ve never done before, and I will postpone it and over-research it as I slowly overcome the psychological barrier to get started, but once started, it has never turned out to be difficult or impossible. And that is a key reason I do (almost) everything myself, it gives you a degree of independence and confidence that is hard to beat.

As plans go, they tend to change, and things took a little longer than initially anticipated in fixing up the house. Adding a nice garage to this house became a must as I’ll likely be here for at least a couple more years. And so it started two years ago. Lots of research, planning, sketching, and constructing later, I am now almost at the point where the tools can be moved out of the living room and into the garage! The idea was: simplicity. Since this is the biggest project I have ever tackled, I didn't want to make it any more challenging than necessary. Some of those choices are to extend the house’s roofline straight out, makes roofing & flashing a breeze. But it does result in a pretty boring, long & straight house Ah well. Can’t have it all. Whenever presented with a choice, I chose the path of least complexity. Remember, this is the practice house! The dream house will come some other day.


This is a rough layout of my lot, the house as it was, including the old carport. The carport is the bit with the flat roof, a terrible idea in New England.

Here’s the same plan, but now with a garage in place to replace the carport. Much better. The house is about 1000sqft, the garage will be about 750sqft, 27.5ft by 27.5ft interior dimension. I like to think I have my priorities right.

And here is a bit more detail on the garage structure. While it wasn’t really necessary to go into this much detail in the drawing for the garage, it did make me think about in a lot more detail, and ask questions in the planning stage, rather than in the execution phase. One more simple thing: I learnt some of the terms I would need in English! It may sound trivial, but it can be difficult to express yourself at Home Depot or with the town inspector when you don’t know what a cripple stud is :)

First step was to tear down the old carport. It has an open portion, and a small utility room in the back. Being a flat roof, it was partially water logged, and generally decrepit. As I found out, the construction crew also cut some corners: the hurricane clips were only nailed to the joists, but not to the house! The effectively did nothing. Want another example? None of the anchor bolts had nuts on them! Later on, when breaking up the old floor pad in the utility room, I found a little rusty bundle. Guess what? The nuts! The must have poured the concrete over them, couldn’t find them anymore a week later when putting the walls on, and let things be things. I am thoroughly amazed the whole thing didn’t blow away in any of the last 60 years worth of hurricanes (on the other hand, gives you a feel for safety margins in construction)

Here’s a view from the top. I rented a boomlift to cut some 100ft oak trees. Had to be done before starting on the garage, didn’t want one of them to come down in the next hurricane on my brand new garage. Both the craziest, and stupidest thing I ever did. The carport is to the left, with the black roof.

She served me well, but boy does it **** to work on a car in the winter in an open carport.

Maximum destruction!

And all gone…

NqCM4GV.png



Alright, with that out of the way, and peak destruction point achieved, it is time to start building up again. The first order of business is, much like the financials involved, to dig a hole. Got a guy to do it with his little tractor, not the greatest job but it worked. I ended up cleaning up the trenches a bit with a shovel so everything was nice straight & level for the footers.

x7HxrVV.jpg



Speaking of footers, that’s up next. Here they are. I insulated the inside of the wall with 2 inch pink board, 2ft deep. Where to insulate (inside, outside?) and how (horizontal, vertical?) was a whole research project in itself. In the end, I figured this was the easiest, and as I said before: keeping the project scope manageable was a key requirement.

RyZXVDz.jpg



I decided to cut down the old footer from the utility room so it wouldn’t have any funky effects on my to-be-poured new slab, and wouldn’t cause any cracks. That’s yours truly.

havtclW.jpg



At some point after this, the slab was poured. Concrete by the way is the ONLY thing I didn’t do myself. I was in a time crunch to get started in the summer, so I would have the roof over it by winter. And I didn’t want 30 yards of concrete in the wrong place, it tends to be hard to move later on. I ended up with an 8 inch slab, which is definitely overkill, but I like overkill. It also meant I didn’t need to call a guy to bring in gravel to bring everything to grade, it was logistically simpler to just have the concrete cowboys pour an extra 4 inches. And now I can rest easy that this thing won’t budge.

Next up were the walls. I will take any excuse to buy a tool, so I got a framing nailer and a very nice compound miter. It was the right thing to do, I told myself. The walls are 2x6’, for maximum insulation later on.

4E36C9o.jpg



Walls went up in a few weekends, I made the 27ft sections out of one piece, so it took some manpower to lift them in place. Luckily I have great friends & neighbors, and the cavalry was happy to assist. My friends particularly were fantastic throughout the whole project, I got lots of helping hands. And I taught them everything I learnt, fair trade. They’ll be ready to build their own garages, and I will go and return the favor.

p50bPjb.jpg



View from the inside. I really got a feel for the space for the first time.

KsK0Pbl.jpg



I only have 8-8.5ft ceilings, which is undesirably low, but a result of sticking with the house’s roofline for simplicity. I toyed with the idea of scissor trusses to gain some height, but the simplicity argument ruled in favor of pre-manufactured standard trusses. Sacrifices must me made, said the Aztecs, as they carved out the heart. I wasn’t sure at all how easy it would be to put the trusses in place, but me and 1 friend got all 13 of them up in 5 hours, with no prior clue on how to get that done. It turned out to be easy, the metal truss spacers definitely assisted in making it even easier. You can absolutely do without, but for the money, it makes it a lot quicker. Don’t even need to break out the measuring tape, these guys hold them at the right distance, and yes, I did keep an eye on any cumulative errors. All remained within tolerances on its own by using the spacers.

x6xLhU3.jpg



Here’s everything up, and a start on the sheathing.

UdMWnvQ.jpg



At this point, it was time to verify my measurements.

f4OBLmD.png



I really wanted to get the roofing on before winter, but temperatures were getting low by now and I didn’t like the idea of suboptimal temps, the shingles won’t bind properly. I’m sure I would have still been ok, but it was one of those cases where my OCD kicked in and I wanted to wait for warmer weather. So tarps were installed, and neighbors were jokingly told they better like the color blue for a winter. They did, but I think they were being kind.

Oh yes, at some point in here also installed the doors, windows, and garage door. I was told installing a garage door is difficult and should be left to professionals, so I said psssh, and did it myself. It was easy. I also installed a Liftmaster 8500, and is that thing ever awesome. If you so much as consider another type of garage door opener, Sir or Madam, you are a fool & an idiot. This is the bees knees. The garage door is insulated, 2 inch, and double pane windows, most R-value I could get. I focused heavily on insulation throughout the project.

After the long winter, it was time to start roofing. Tarps finally came off, and stripped the old roof. It was still good for another 10 years I reckon, but I wanted to do it right and get everything nicely matched, and of the same age, so that it will all be on the same replacement cycle. This also gives you a rare look from the rear, 2 windows and a door to the backyard. The windows don’t open, which was chosen to maximize their thermal performance. Less seals that can leak. It’s a garage, if you need a breeze you can open the door.

With the help of many friends, the roofing was completed in one day! Pretty good for an inexperienced crew, we put 22 square down on Saturday as there was a chance for rain on Sunday. I did rip almost everything off the Friday night before, tarps and shingles, so we could get crack-a-lackin at the break of dawn. It was a long day and I was beaten, but my friends are so awesome I didn’t even have to feed them, they brought their own BBQ :)

You sure are brave running your calculations with such a narrow margins of error. I'm glad the car fit :rocker:

I personally would of added an extra 10 feet just to be safe :lol:

Post more that is looking great!

Great project and there is no need to apologize about "Construction OCD" as many of us have it too! Good call on the LiftMaster, I love mine--so very quiet and the ceiling is so much cleaner looking without the third track.

Nice job. I was wondering how you were going to match the roofing since the roofs are contiguous, and kudos for re-shingling the entire house and for switching to black shingles, which I think will update the look of your house. Good work.

I am going to subscribe to this thread for the following reasons:

1. You are doing a great job!
2. You are doing it yourself with your buddies
3. You followed the roof line of the house, very smart!
4. You said "Bees Knees"

I am enjoying the garage build, nicely done. The stake bed on your truck is really cool, any more pictures of that?

The man-lift picture brings back memories for me, I rented a 125' lift to take down 5 trees before I started my shop. From 100 ft in the air I got real nice lake view property...haha

Little overdue, but I promised to take you through the inside next. I travel a good amount for work, so there’s not a lot of time to work on the garage in between, and when there is, no time to post about it.

After the roof was done, interior finishing was next in line. Me and a friend put all the electrical in, we installed an ample serving of outlets, 3x simplex 50A 240V, 5x simplex 20A 240V, 6x duplex 20A 120V, 2x simplex 20A 120V. I have at the most 2 outlets per breaker, so that’s on the conservative side of chainganging. I don’t have pictures of it, but the inspector said we did better than most electricians, that was a nice compliment (unless it reflects more on those electricians, but I’ll give them the benefit of the doubt..). There's a subpanel in the garage that is fed by a 90A breaker and 2-2-2-4 alu cable.

We then tackled the ceiling. I have OSB board covering the entire inside, and on top of that 5/8 FireX sheetrock, so the interior walls end up being a solid 1inch thick so you can screw something in the wall anywhere you want without having to look for studs. It'll also help add mass for soundproofing. We did the ceiling first as I wanted to have the light fixtures in so we could work in some decent light. Speaking of light, here’s my lighting plan:

kjTajmF.jpg



The matchsticks perfectly represented 4ft lights, as I scaled the piece of paper for that very reason. I had decided on 4ft 2-bulb T5’s, 28W bulbs (I think they’re Lithonia, Home Depot around $30 each), partially because the T5 look more modern, and partially because with the only cheaper option I’d need electrical boxes, and the cost of those plus the extra hassle made it less attractive. The row of lights perpendicular to all the others is where the workbench area will be. Everything was evenly spaced. I calculated I needed around 19 fixtures for the lumen/sqft required, which seemed excessive to most normal earthlings, but I checked my calculations and that really is how many I needed for about 100 lumen/sqft. We put the lights on two circuits so you can use only half of them. Walls and ceiling are going to be white as well, so it will be lit up like 1991 Kuwait.

My dad was visiting and helped with the ceiling, as well as a bit of the walls already. I bought the drywall lift after all the OSB and most of the drywall was already up, and it was still worth it.. next time I’m making sure I have one from the start.

iy89ynr.jpg



Lights installed! Also started insulating, you’ll note the walls already have all OSB on them, and are already insulated (note the blow-in holes at the tops of the walls). That was an easy job, I reckon I have about R24 in the walls. The stack of insulation on the floor is about to be blown in the ceiling, which will have between R30-R50 (the central aisle will be R30 since that will also be available for storage, less space for insulation since it will have an OSB floor).

qjsKRdI.jpg



Let me say that it is very bright in this garage. Sunglasses and SPF 30 are recommended. I love it, and I would do the exact same thing again.

I made another thread to discuss the floor, and I’ll post more there. But here’s a picture, and despite my goofup with the flakes, it looks spectacular. First car in the garage, and it isn't even mine! Friend came over to change his wheels. All walls are drywalled and ready for paint!

Primer on the walls:

And a panoramic shot of the fully painted walls. Almost finished, cover plates, some trim, and I’ll be done! That'll be for 2015 though.

And a few more pictures of the truck as requested, she'll be the first major project in there once everything is done :)

1987 Toyota Pickup. Going strong but she's a lil' rusty. Here we are picking up my woodstove from Woodstock in Vermont last year. It was a 1 degF day, perfect day to go get a woodstove. Got a tour in the factory too, nice folks.

And I have a lot of friends help me out, but you've got to feed the beast, so to speak. Time for an empties-run, that flatbed sure has a lot of utility value!

Haha, bit of both maybe :). I'm not complaining, i have everything i need and more, luckiest ~10% in the world. For sure homes are more expensive here than in the South, also building materials, labor, gas, everything really. But mostly i'm a cheap ******* and i just got something rundown, and cheap (for these parts).

I'll post a breakdown of the garage building cost, i have everything in a spreadsheet.

I'm giving up on trying to make a table... My permit was based on $20,000 (pulled the number out of my *** at the building department, if I hadn't gone overboard on a few things I would have been pretty close, certainly for a wild guess!)

Item Cost
doors $2,209 (2 entry doors, 16 ft garage doors)
electrical $969
floor $1,782 (epoxy + tools required)
framing $2,509
insulation $600 (blown in atticat)
interior walls $1,358 (OSB + drywall + paint)
lights $1,108 (this was less, other items were on the same receipt)
permit $338
plumbing $101
roof $2,476 (plywood, weatherguard, underlayment, shingles)
siding $1,484
windows $546 (2 windows)
concrete $8,520 (650 excavation, 4000 labor, rest concrete + foamboard perimeter insulation)
Grand Total $24,000

Everything is pretty close to accurate, sometimes I bought some smaller items on the same receipt and I didn't bother separating that out from the big stuff, but that won't make a material difference. Only exception are the lights, that should be more like $700, so I must have bought some other things at the same time.

Could have save $1000 on concrete (4 inch slab instead of 8 inch that I have now), and lose the OSB on the inside, just do drywall (save $800), maybe shop around for the concrete labor (I went with the guy my inspector recommended, did good work, maybe I could have gotten a little cheaper somewhere else. And I should have discovered home depot pro desk sooner, I could've probably saved on the roof, I got the plywood and shingles from the lumberyard. I would probably stick with framing materials from the lumberyard for quality reasons, but on shingles, for the exact same product, they're more expensive. All in all I could've probably shaved off about $3000, but I prefer knowing that it is overbuilt to $3000. I might do concrete myself next time, that's $4000 in labor, but for a first timer I didn't want to get that wrong, it's pretty irreversible.

Big surprise to me was that the concrete (material + labor) is about 1/3rd of the total project cost, a decent slice of the pie.

GG: nicely done. sure you could of maybe saved a few bucks by pouring your cement cheaper, but the odds of it cracking should be nil now which is worth the extra money. also the added wall boards will be nice if you go to hang shelving or cabinets.

i didn't see the stove in the cost breakdown so curious what you spent on a stove and also looking forward to seeing the installation. is it wood or pellet or gas?

my dad graduated from Yale so i know a little bit about Connecticut and i'm not sure I've ever heard of a hurricane coming through there unless you got the rains and wind from Sandy a couple years ago. do tell and when did Connecticut get put on Hurricane watch?

now that you are a GJ member i would be curious if the tool expenses will surpass the garage build costs. my guess is yes, but you'll need them all eventually just like the sheet rock lift.

cheers

It's a woodstove, Woodstock Progress Hybrid, including chimney and all accesories it ran me about $4500. I'm not counting it here because it was for the house, not for the garage specifically. I did oversize it so that i can heat up both house and garage with it, my kitchen door opens to the garage, so all I have to do is open the door and put a fan in.

Yeah, tools are going to be a decent investment! I love high quality tools... My excuse is i buy them for life.

You're from Belgium and your writing skills are better than 90% of the American population. Thanks for taking us through your project. It would be a shame to leave that all behind someday. You might even call that a garage with an attached house.

Thanks Zeke! You may not believe this, but I learnt English from The Simpsons :). And Bruce Springsteen, haha, I still remember singing along to his LP's as a kid!
