THE「Exterior Work」Converting a 20-tsubo backyard into a concrete parking lot! How much does it cost?

The dirt zone behind the factory—we recently completed the exterior work.
It would have been much more affordable if we’d done it during the factory construction.

I was thinking maybe we’d build another small factory on that dirt area. If we did that, pouring concrete first would mean paying to remove and dispose of it later.
That’s why we put it on hold.


Four months have passed since we moved, and it’s not realistic to build something else in this space.
So we decided to turn it into a parking area instead.

It costs more than expected—1.76 million yen! (*´ω`*)

Since I have no idea about the market rate, my comparison is more like “I could buy a light truck for that!” I’m grateful it’s reasonable, but I’m satisfied with the work, so no complaints.

About 5 days of work. Fortunately, the weather was great!

I completely forgot the work was starting that day.
Fortunately, I’d moved everything out, so they got started right away.

DAY 1

That day they dug up the soil and removed unwanted materials.
Then they dug trenches for the blocks.

DAY 2

The work progresses smoothly.
The blocks are laid down and the base is taking shape.
Thinking that this soil will soon disappear gives me a bittersweet feeling.

DAY 3

They repeatedly removed excess soil and then added crushed stone and compacted it.
The small machine is powerful—it vibrates all the way into the shop.

They also raised the septic tank a bit since it was slightly too low, making it accessible for inspection.

DAY 4

That day they laid wire mesh in the concrete area.
And they extended the PC fence.
Using PC fence gives it a cool, rural American vibe.
I can see why it’s become trendy lately.

DAY 5

It was a busy day with concrete trucks and pump trucks everywhere.
Since it was a Tuesday, I asked them to proceed and went out.

Three workers smoothed it out together.
We really had perfect timing with the weather and temperature.
If it had rained during the process, it could have been significantly delayed.

Wow—when I got back, it looked like this!

The space of about 20-plus tsubo is now usable.
I could put a storage shed there, or line up visitors’ motorcycles.

I could also just place some chairs and relax here—there are lots of possibilities.

It’s more spacious than I expected, and both the appearance and usability have improved significantly.

Still drying?

They’ll come back to remove the remaining wooden frames at the right time.
It’s probably safe to use now, but since I have no immediate plans, I’ll leave it as is.

This 20-plus tsubo of land would cost 60-70 million yen in Tokyo’s Jonan area. It’s amazing, isn’t it?
The countryside is affordable and offers great environmental freedom.
Plus, there are no restrictions around here, so it’s a wonderful environment for running a motorcycle shop.

In these 5 days, it’s been completed like this. I’m pausing equipment investments for the rest of the year.
I’ve spent too much money this year, and the coordination and decision-making are quite tiring.
For the rest of the year, I want to focus on work and refine the smaller details.
