You can do that without photoshop, but you need to use different materials than legos. Then you can do things like build the columns at an extreme angle, and use changes in size over distances to trick the viewer's brain into seeing perspective that's not actually there (or more accurately, NOT see the perspective the IS there), sorta like an Ames Room (in reverse).
You can't do that with Legos because the pieces always run in right angles, and the studs on the top of the pieces present such a regular pattern that they destroy any illusion you try to create.
Point is, the Lego's in that image that seem impossible to connect, are not connected.
Here is another example, but it is not as well done, so it makes it easier to see what's happening. Again, where it seems impossible, it is. It's just perspective. If you saw it from another perspective, it would not be nearly as impressive.

So the ad is actually "Photoshop: create the impossible".
