When kids grow up, their childhood rooms just don’t work anymore. At that point, you know that it’s time to make a more teen-appropriate space. It’s emotional sometimes, but it can also be pretty awesome.

That’s what GeekDad blogger Randy Slavey experienced. What he recently posted on his blog is probably one of the most impressive kid’s room makeovers we’ve seen in a while. His son just turned 13, and it was clear that he’d outgrown his childhood room. Slavey knew that his son was really into the Portal video game franchise, so he and his wife took that idea and ran with it.

If you didn’t know better, you might think this was a screenshot from the game. But it’s actually even cooler.

First, his son’s old furniture was broken down and dismantled.

Slavey wanted to repurpose it at first (partially, he admits, for sentimental reasons), but it ended up not working for this project.

After the walls were primed and painted, they mapped out the desired pattern with tape.

These circle details were painted by hand.

The new furniture also had to be painted.

Slavey and his wife learned a valuable lesson: don’t by the two-in-one paint and primer. It chips too easily! It’s totally worth it to sand, prime, and then paint.

Under the desk, Slavey included a secret message. Fans of the game will get this reference.

For a cool centerpiece, Slavey used mirrors and colored rope lights to create “portals” in the room.

When positioned across from one another, the mirrors reflect infinitely, creating the illusion of an endless tunnel.

The room finally came together!

And it looks pretty awesome.

The closet doors were painted to look like the doors between rooms in the game.

Any fan of the Portal series knows that it wouldn’t be complete without these two elements.

The turret is a wall decal, in case you were wondering.

…it’s obvious how their son felt about the new room.

There are even more awesome shots of the room on his blog, along with a few of his son’s birthday cake (which was not a lie). You can see those photos and more over at GeekDad.
