Well i converted my garage into an office, sound and thermal proofed it, layed out drywood walls and the structure needed, painted, did the flooring and underlaying too. Took me a week and a half. A fun project. But i do admit i forced my self to step out of the tech bubble and learn other skills a few years ago, just for myself. It was a really cool project. It can take longer when you have zero experience but once you build it up just a little bit it can go fast.

As an added bonus, i made sure my network cables running through the walls are 10 Gbe. Just in case :-)

I absolutely recommend to anyone working in tech that they try it.
