Building my Backyard Office

In 2020, I build my backyard office. Here are some finished pictures first:

First, some background

When Covid hit in 2020, my company shifted to being fully remote. We had one child and another on the way, and while we were fortunate to have a nice house to live in, I didn’t have a dedicated space to work from. With working from home as my new normal, I started thinking about what my ideal working environment would be.

My dream was to have my own office detached from the house. It seemed like this would be less expensive than adding on to the house and potentially something I could tackle on my own. But could I actually do this?

I was intimidated by the fact that I did not have the skills yet that I would need to do the project, and I also knew it would consume our family’s time and energy for several months. For those reasons, despite the urging to go for it from my wife (who might have been ready for me to not be working out of our kid’s room!), it was difficult getting to the point where I was ready to say “I can do this” and pull the trigger. But, in June of 2020, I decided to go for it and got started on the project!

Some preliminary research

I spent a few months researching various aspects of the project prior to starting it. The first step was checking my local building codes. In my city, we don’t have to get building permits for detached structures that are less than 200 square feet, but we do still need to permit any trade work, like electrical or plumbing. Where I am, homeowners can also pull their own permits and do that work themselves.

I then looked up the required property setbacks in our building codes and examined my property survey for boundaries and easements to determine how close to the property lines I could place the office. Where I am, it would have to be five feet from the side of the property, and I have a 7 1/2’ easement at the back of the property for underground electric utilities.

After determining the size and placement of the office, I used my favorite design tool, SketchUp, to design the office, which you can view here. At this stage, I was determining the height of the walls, pitch of the roof, and sizes and locations of windows and doors. I had found a huge window off Craigslist and designed much of the space around that window.

The build

Building the office required me to learn a lot of new skills and do some hard work. I spent the evenings during the week learning and planning, mostly on YouTube and other construction sources, and then dedicated the entirety of most weekends to building the office. My in-laws were a huge help here. My father-in-law helped out almost every weekend with the construction, while my mother-in-law assisted my wife with watching our one year old daughter. I couldn’t have done this project without their support and the support of my wife!

Here are the main milestones of the project:

June 10: Kicked off the build. Started leveling the ground for foundation

Jul 18: Roofing installed
Jul 25: Doors installed
Aug 8: Trim on corners, door, some windows. Started siding
Aug 26: Dug trench for electrical
Aug 31: Most of Hardie Plank siding installed around three sides, two left windows installed

I was able to work out of the office just under five months from the day I broke ground on the project. The only work I hired out was an electrician to install a sub-panel on the back of the office.

Photo progress

I haven’t gotten around to doing a detailed writeup about the build, but here are some pictures of the process:

Office SketchUp render — I designed the project in SketchUp. The designs evolved a bit as I went, and this is actually what it looked like at the end of the project.

Inside render — Another render, of the inside.

Tilling for foundation — I rented a tiller to dig up the grass for the foundation.

Foundation in place and adding chicken wire to keep skunks out, which are prolific in our area. The foundation was cinder blocks sitting on about 6" of sand and pea gravel. Three 4x4 skids were placed on top of these blocks followed by the base foundation. I don't live in a cold climate where it's necessary to tie posts below a deep frost line, and our lot sits on solid limestone, but if I could do one thing over with this project, it would probably be to make this foundation more robust, mostly to prevent eventual deterioration or rot. I haven't had problems with it yet, but I do worry about how close to the ground it is.

Foundation and walls up — Starting to get the walls up.

Walls up — I was surprised how quickly the walls went up. I bought an inexpensive framing nailer for this project.

Sheathing started — Starting to add sheathing.

Sheathing mostly on with some imperfect weatherproofing.

Inside — A shot inside the office with the big window installed. My daughter, Wren, liked to check up on the progress.

Metal roof — I rented a truck and picked up the 18' long panels for the metal roof. Since I don't have a large vehicle, I rented Home Depot trucks quite a bit during this project in addition to having lumber delivered.

Doors and windows installed — Doors, windows, and metal roof installed. This is not a brand advertisement. My neighbor who works at Home Depot was not excited about the blue logos.

Starting siding — Added cedar trim and starting to add Hardie Plank siding, which was easy to cut with a carbide blade in the circular saw.

Electrical plan — I drew up this *wayyyy* overcomplicated electrical plan that I attached to my permit paperwork. Five circuits was pretty overkill for the space.

Lighting layout in SketchUp — Planning the lighting layout. Not sure why I took a picture of my screen.

Electrical roughed in and ready for inspection!

I dug this 50 foot long trench with a shovel. I hired an electrician to run electrical from the panel on my house to a new sub-panel on the office. While the trench was open, I also diverted some sprinkler heads, and added ethernet and water to the trench, both of which I tapped off of the house for.

Adding insulation — I passed the electrical rough-in inspection and was able to start with insulation and drywall!

Electrical turned on, adding drywall — Power on, finally! It was so nice having plugs and lights. You can see that I also started getting the drywall in place.

Drywall mudded and pine wall and ceiling added. I finished after this by skim coating all the walls for a completely smooth finish.

Moving in — I skipped a few steps in the pictures, but engineered oak floors went in after drywall, and I was able to start working from the office! It would be another month or two before I finished the bathroom and kitchen and trimmed the windows.

The bathroom. This isn't tied to the sewer and drains to a "dry-well", which is basically a large trash can buried underground with perforations in it. The toilet, which is actually an RV toilet and is used for "number one" only, has been incredibly convenient to have.

Careful bathroom design — I had to design this tiny bathroom very carefully. It is the smallest width allowable per code (15" on each side of the toilet), and the door barely clears the sink.

Kitchen complete — I had a Covid exposure during Christmas of 2020, so I quarantined from my family in the office for a week and used that time to build this kitchen. The cabinets and countertop are 18mm baltic birch, and I added a glue-down laminate to the countertop.

New shelf — In 2022, I built this shelf for the wall next to the couch. This is the backdrop for all of my video calls. I don't usually use pine much for my house, but I really embraced it on this project. I like the casual, understated feel that it gives in this space. I also used pine for the console table that the TV sits on (which I built in 2016), the window trim, ceiling, and one wall.

Side wall, another view — Here's another view looking to the left side of the office.

Wrapping up

I have been working out of the office for almost three years now and am so happy I chose to build it. It was a wild and exhausting ride planning and building it, but very worth it. I still enjoy stepping into this space daily and feel the deep connection that comes from pouring labor and creative energy into something.

And now, for symmetry’s sake, I’ll wrap up with the couple pictures this post started with:
