Author here. Thanks for the comments everyone!

There are many comments on the price point. I would like to comment on one thing.

"$20k is too much"

I agree $20k is an investment. Could I have done it for cheaper? Absolutely. Would a DIY shell been cheaper? Would doing more of the work myself have been cheaper? Could I have saved by putting in the smaller stock windows and not having a skylight? Of course!

But I am a dad with a young kid, he was 1 when I built the office. I didn't want to spend my limited free time on this project. There was a trade-off between paying for labor and the time it would take to do it myself. At this point in my life I always look at these decisions through a lens of: is the cost savings worth my time. In this case I valued my time more than the cost savings. I was lucky enough to be in a situation where I would rather spend money for someone else to build this then spending my nights and weekends on this project.

I am almost 4 years in I would have paid over $20k for a co-working space. We were able to stay in our smaller house with a ridiculously low mortgage rate. We made the right choice for us.

Cheap is relative. Sometimes your time is worth more. There are litteraly entire companies built on this premise, cough DoorDash

> I am almost 4 years in

Also worth mentioning 2026 - 4 = 2022. Not a great year to be stick building from a cost perspective.

I'm in the middle of finishing out my own (significantly larger) shed I just had built, basically all DIY except for the structure itself. The number that popped into my head at the start of your post was $30k - each step adds up when you're paying small job overheads. That you did it for $20k is pretty great.
Re:Building a backyard office, the build and cost breakdown by bellowsgulch on Tuesday August 25, 2026 @05:05PM (#49440627)
That you think $20k was a good deal for this shack in your backyard is indicative of how little we know about building.

You got raked over the coals. You can downvote me, but as someone who knows how to build structures man, I feel so sorry for people reading your message thinking this is OK.

This is really, really poor quality for the cost.

I’m not even a commercial builder. A bag of Portland cement concrete is $5/bag. You don’t need to pay $2k for such a small foundation.

Re:Building a backyard office, the build and cost breakdown by MattGrommes on Tuesday August 25, 2026 @06:16PM (#49441439)
Beyond the fact that there's absolutely no reason for you to post this, I'm not sure what you're looking at. I'm not a pro but I've been building sheds and things for decades and based on the pictures here I don't see low quality. Maybe I'd put more joists in the roof but Portland doesn't get a ton of snow so I'm sure it's fine. $2k is a fine price for that slab, especially compared to the pain of lifting 80lb bags of concrete yourself all day. People shouldn't be afraid of spending the money on a pro if they've got the money to spend.

Maybe he could have saved a few thousand with different subs (maybe) but your comments are nonsensical. I see tons of janky builds people post on Reddit and this is not one of them. You should spend your commenting time over there.

i think it is pathetic that your rebuttal to a comment you dont like is go back to reddit

youare the same type that tell foreigners to go back to their country because you dont like being called stupid more than you dont like actually being stupid20k for this is a joke like yoi

And he built a $20k shack with asphalt shingles and T1-11 siding. A fool and his money are quickly parted is the current state of building in America.

It looks poor, it is poor.

But we also have a whole nation who thinks paying rent, an HOA, who can take your home from you, is a good idea so everyone can look equally poor together in lower middle class homes with textured walls.

That you don’t is a problem.

The expectation is higher.

PS I was saying that $20k is too little to spend for this type of thing - not a great price for this result.

Re:Building a backyard office, the build and cost breakdown by jasonpeacock on Tuesday August 25, 2026 @05:41PM (#49441069)
It's not $5/bag. There's also tools to be bought or rented, knowledge and skills to learn, and time spent. $2k is the cheat code to skip all of that.

My calculus is to evaluate time, cost, and quality. If someone can match or beat me on 2/3 of those dimensions then I'll hire them.

Re:Building a backyard office, the build and cost breakdown by bombcar on Tuesday August 25, 2026 @05:52PM (#49441200)
He's getting downvoted, but he's not wrong - however, finding someone who specializes in doing this would be hard, and knowing how to word it so you can use "standard crews" would itself be $2-3k for a GC.

This is the danger of "cheap projects" - they can grow legs before you know it, and you end up paying half the cost of increasing the square footage of the house (or the garage).

Re:Building a backyard office, the build and cost breakdown by turtlebits on Tuesday August 25, 2026 @07:30PM (#49442143)
Yeah of course you could DIY this or find your own subs much cheaper, but in the grand scheme of things, it's not that bad.

You get a finished and conditioned room, and it most likely added value to his house.

Re:Building a backyard office, the build and cost breakdown by tclancy on Tuesday August 25, 2026 @10:23PM (#49443430)
Unless he’s a commercial builder, I’d suggest he is wildly wrong about what is involved in properly pouring, leveling and making sure concrete has properly set in various weather conditions. And if you take a look at his post …
Re:Building a backyard office, the build and cost breakdown by lelanthran on Wednesday August 26, 2026 @02:29AM (#49444823)
Some things are deceptively complex (foundations and roof trusses come to mind) and the cost if you get it wrong can easily double the total cost of your build 6 months after you think you are done.

Walls, floors, ceilings and everything in between them are both less complex and cheaper to fix than foundations or trusses.

It's a shed, you can just compact gravel and put it on pavers
Re:Building a backyard office, the build and cost breakdown by quickthrowman on Tuesday August 25, 2026 @05:57PM (#49441250)
> I’m not even a commercial builder. A bag of Portland cement concrete is $5/bag. You don’t need to pay $2k for such a small foundation.

An 8x10 6” slab has 1.5 cubic yards of concrete. Making concrete takes more than a bag of Portland cement, you also need gravel, sand, a mixer, a wood frame, a source of water, shovels, floats, et cetera. If you want rebar, add in steel and rebar tools and wire.

You could frame up the wood yourself and have Cemstone deliver the concrete but you still need to spread it out, float it, and finish it.

Instead of buying or renting all of that, I would sub it out. I subcontract out light pole bases and concrete pads for transformers, EV chargers, and other equipment all of the time.

Re:Building a backyard office, the build and cost breakdown by kevin_thibedeau on Wednesday August 26, 2026 @01:24AM (#49444338)
It isn't easy but you can economize with 4" in the middle. It will still be a lot of concrete to mix up if not using a truck. Fiberglass rebar is easier to wrangle for a DIY job as well.
Re:Building a backyard office, the build and cost breakdown by skew-aberration on Wednesday August 26, 2026 @01:45AM (#49444486)
60lb premixed concrete bags are $5 in the US, and getting it delivered would be cheaper at this scale - the slab could cost under $500. The other costs sound normal -> materials + markup + labor. The more realistic money saving would have been a prefabbed module that doesn't need a slab for less than half the price. It would be easier to get rid of / sell in the future too. This looks much nicer though.
Re:Building a backyard office, the build and cost breakdown by tclancy on Tuesday August 25, 2026 @10:21PM (#49443414)
Huh. I would have gone the other route if I was going to rant and say there’s no way to do this for so cheap because I’ve looked at replacing a shed in NH with something a bit more sizable and while you can get a nice looking prefab for like 6-8k, that’s before the pad. Add in real windows and a mini split and insulation and I’ve no idea how to keep it that low, but I am jealous.

You can buy all the Quickcrete you want (not sure the last time you priced it), but it won’t make you good at pouring a level pad. That alone puts me off trying to do it some days.

Re:Building a backyard office, the build and cost breakdown by conductr on Tuesday August 25, 2026 @05:11PM (#49440689)
My 12x16 took way more time, but I did it all myself. I mostly worked at night once the heavy loud stuff was done because of the young kid factor. But at only a couple hours a day, it took about 4 months. Although I did build mine down into a ~3 feet deep basement of sorts which complicated it (I didn’t want it visible from outside my fence). Even did off grid electric with solar to avoid needing contractors or permits. I won’t hate because I get the time trade off, and I really hate/appreciate a few trades more than before (drywall the most). For reference mine was $15k in 2025.

The main thing I’d advise people against and say you could have possibly saved on is the structure. Tuff Shed is usually over priced and could be built usually with $2k-3k of material and labor. But the time you did this may have made that hard too, all the contractors were slammed.

Re:Building a backyard office, the build and cost breakdown by DANmode on Wednesday August 26, 2026 @12:25AM (#49444155)
$20k is too little.

Thank you for the cool post.

I am very glad that the grainy 40 year old photos of me at that sort of age with my father are us digging a hole together or me crawling around on a freshly poured slab of concrete - rather than at a soft play venue.

Re:Building a backyard office, the build and cost breakdown by oblio on Wednesday August 26, 2026 @05:21AM (#49446089)
What are you going on about?

What memories with a 1 year old? Besides the fact that it's almost impossible to actively access memories from when you're 1 year old, a 1 year old shouldn't be anywhere near a construction site.

There are much better and safer uses of time together with a 1 year old that don't revolve on hoping they'd see a grainy (or nom grainy) photos 40 years later.

Re:Building a backyard office, the build and cost breakdown by blitzar on Wednesday August 26, 2026 @05:50AM (#49446329)
> memories

I did not reference memories anywhere at any time. I did not imply or state that I had memories of such, could access memories of such nor suggest it was possible in any way.

My handprints however are still in that concrete slab to this day.

Re:Building a backyard office, the build and cost breakdown by oblio on Wednesday August 26, 2026 @05:53AM (#49446354)
Doesn't really matter. Why would it be better to be around a construction site that at a soft play center? Since you cannot remember anything voluntarily, anyway?

I understand the choice of a different activity for a 4 year old or something, or even for a very calm and prudent 2 year old.

Just for the photo? Who cares? You could have had the same grainy photo at the soft play center and it would have been as nostalgic.

I hate these ill intentioned judgemental comments like yours.

Do you have a mirror handy by any chance?

Re:Building a backyard office, the build and cost breakdown by oblio on Wednesday August 26, 2026 @11:53AM (#49451273)
Yes, I do. And that's why I came down hard on the previous commenter.

Someone shared their benign personal experience and the FIRST reply was the Holier-Than-Thou typical garbage of "akshually, you're a bad parent because you did not do X Y Z parenting micro-optimization".

Re:Building a backyard office, the build and cost breakdown by n4r9 on Wednesday August 26, 2026 @06:26AM (#49446610)
You both have valid points.

One one hand, "implicit memory" [0] begins at birth and being around one's father building impressive things is a huge bonding experience. Research seems to say that even at 1yo these things imprint on our brains.

On the other hand, it shouldn't get to a point where a 1yo is crawling into freshly laid concrete. There are safer ways to do it.

Re:Building a backyard office, the build and cost breakdown by oblio on Wednesday August 26, 2026 @07:00AM (#49446870)
There are more than enough years past the first one for the "father to build impressive things", though.
Re:Building a backyard office, the build and cost breakdown by n4r9 on Wednesday August 26, 2026 @10:26AM (#49449843)
The 1yo stage is surprisingly convenient for that sort of stuff. At ages 2-4 they're much more mobile and experimental and harder to watch. Then from 4 or 5 upwards they're at school a lot and starting to lose interest in what their parents want to do.

Also, the first 18 months establish a good deal of a person's attachment security, connection to parents, and emotional intelligence. The brain continues to be flexible for some time, but gradually becomes harder to rewire.

Everyone's experience is different but:

> Then from 4 or 5 upwards they're at school a lot and starting to lose interest in what their parents want to do

I had to disagree with this. Thought this might be a European experience, in the US there probably isn't a lot of time to interact with the kids during the typical work week.

I would say that interest in what we do has stayed steady if not increased after about 3 years old because now they understand more things.

At this rate I expect the "losing interest part" to start during the tween (8-12) or teenage years.

Re:Building a backyard office, the build and cost breakdown by phil21 on Wednesday August 26, 2026 @11:19AM (#49450724)
Hard and very vehement disagree from me.

So long as it is safe, a kid even at 1 years old should be tagging along with the adults doing things. Like building, working out in the yard, helping friends with projects, whatever.

It is very settled science that brain connections happen rapidly in these years. Bubble wrapping your children is not the way to go in my opinion.

Everyone is going to have a different take on this, but for me the choice is immediately obvious. Kids should fit into your life (within reason), not have you change to revolve around theirs.

That said - I highly doubt a 1 year old did much more than watch and have short visits while being cared for by someone not doing the construction work. It’s a great bonding experience even with limited direct involvement.

Re:Building a backyard office, the build and cost breakdown by oblio on Wednesday August 26, 2026 @11:55AM (#49451318)
A half-mobile 1 year old can be quite hard to control. There is more than enough time for them to bond during a construction project in the following as-many-years-as-they-want-to-tag-along-until-adolescence-hits-hard".
Re:Building a backyard office, the build and cost breakdown by mindslight on Wednesday August 26, 2026 @10:43AM (#49450100)
That does absolutely nothing for the time crunch. I'm more than happy to give my young child tours of my small construction site or whatever other projects are in progress. But it's not like I can also be working on things while doing that. And someone else was taking those pictures, right?

Hey I just wanna say, way to go, I loved your post. I like how you went on what I think is a good combination of DIY and paying people to do stuff. This is really relatable, I feel like most of the decisions in projects are deciding on what to focus on when.
Re:Building a backyard office, the build and cost breakdown by legitster on Wednesday August 26, 2026 @11:20AM (#49450744)
If I would give a bit of pushback, it's really, really hard to understand the value assessments if you've never done the work yourself.

Part of the reason someone DIYs isn't that you're just trading time for money, it's that you understand the value of what you pay for in expertise. Even if you contract out in the future, you'll be better at getting value.

To put it another way, DIY is an investment in yourself. The things you learn doing the work you get to keep forever.

Re:Building a backyard office, the build and cost breakdown by PaulDavisThe1st on Wednesday August 26, 2026 @11:28AM (#49450871)
For myself, the biggest cost to doing DIY over many, many years has been an unwillingness to hire contractors because I know I will do the job better than them.

There are a few exceptions:

1. pouring a concrete pad (too dirty, too much work, needs a crew to really be done right) 2. adobe mud plaster (once you've seen people who know what they're doing do that thing, you'll know why) 3. diamond and venetian plaster (same as #2) 4. 3-phase anything (i understand the concept, but that's not enough)

but electrical, plumbing, framing, finish carpentry, flooring ... I'm sorry guys, but I'm better and I care more than most of you.

What I'm not: faster than you.

I'm sure there are amazing trades folk out there who could put anything I do to shame, but finding them and being able to pay them is another story altogether.

Re:Building a backyard office, the build and cost breakdown by fdgwhite on Wednesday August 26, 2026 @12:38PM (#49452013)
