The office on the photo is the most interesting building in the neighborhood. It is interesting and mysterious: no one knows what's inside.
I've added something suitable on the photo to feel more comfortable about this fact.

In order to properly display this Portal turret, I had to re-create the part of the fence. It looks a bit different from the real one, but you'll notice it only if you know that it is a model.

Unfortunately, I can't say the same about the grass that I had to re-grow. There is a visible difference on the large screens, but as for me, it looks OK on Instagram (primary platform of this art).

I've made a lot of photos of this office (and probably gained an attention of its security staff), but only one photo had these beautiful guidelines.
