Okay. This will take a bit of effort to explain, but here goes:
First take a look at the angled concrete edges on the left. Those are completely arbitrary forms in relation to their use. They are load bearing (supporting the stairs, retaining the exterior foundation, and supporting the windows), yet their form is not intended to produce the most efficient structural strength. Structure is highly rational by nature, as it's meant to oppose orthogonal and lateral forces acting on it, hence the reason it is most suitable when used orthogonally (wall or post perpendicular to floor) or transpositionally (a dome, which gradually distributes loads from horizontal to vertical to convert tensile stresses to compressive stresses). The way that lower edge extends over the floor without meeting the floor is totally contrived, because it doesn't distribute the weight of the stairs and exterior wall down to the floor like domes and walls do. So in essence, it's ornamental structural and only wastes materials. This makes sense, because the silly form is only meant to mimic the ridiculous irregularity of the windows behind it. It's basically an extrapolation of a bad idea from the exterior to the interior, which the architect must have felt obligated to do to maintain the intended level of abstraction and irregularity.
A big problem with using that excessively abstract geometry is that it provides no beauty, because it exposes no truth to the nature of architecture, which is bound by physical resistance to forces. It's entirely superfluous, in contrast to complexity or ornament that is rationally integrated within the form of the building (such as decorative brick pattern or stain glass windows). Even worse, it further complicates the construction. Concrete has to be molded by building formwork out of something (wood usually, or re-usable PVC molds). So to make that stupid jagged edge, they have to spend a whole bunch of time cutting and fitting those acute forms together, which is antagonizing to the economy of structure (repetition: good ; anomalies: bad). You'll also notice how the expansion joint runs vertically, but it divides the concrete facing into irregular portions. This is bad, because expansion joints are meant to allow for the concrete to expand and contract without cracking it, so they are typically designed on very rigid modules to maintain equilibrium in stresses along the entire concrete surface (see Kahn's Salk Institute wall below). But because a larger portion of that face is further distributed from the expansion joint which terminates at an acute angle to the facing, that area will be more prone to cracking, which compromises the entire structure. So in effect, the retarded window shape on the outside is contributing to the future failure of the interior wall, all because the architect was too stubborn to recognize the unintended consequences of making architecture a mere game of creative formalism.

Properly designed expansion joints that equally distribute stresses:


So now look at those fucking wood slats. First of all, it's hard to tell whether they are meant to conceal something or not. They conceal the stairs, but for some reason the architect chose to use a stupid pattern of voids and slats which doesn't correspond to any particular need for something behind them to be concealed. If there is a void, it should be there for a reason and reveal something behind it. If the architect merely wants to reveal 33% of the space to give us the impression that something is behind the slats (like legs of people on the stairs), he should have used a continuous 2:1 ratio consistently across the entire stairs. 2" Slat, 1" Void, 2" Slat, 1" void, etc. That would be less visually cluttered than the silly 3-x-1-x-3-x pattern he's using.
As for the slats on the bottom, it appears they are entirely superfluous wall decor, hence the even sillier pattern that randomly exposes tops and bottoms. And if he feels obligated to conceal something behind it that may be ugly (like that ugly brown wall) he sure as shit should have concealed it fully, as this only allows us to notice the ugly brown wall he's making a contrived effort to cover. And why the slightly crooked angle? And why are the slats different from the ones right above it? They should be uniform, but they aren't, because they're fucking shitty. Here's what well designed wood slats look like. Notice how the void between them was used as a means to integrate light and subtle visual texture. There's a function to the ornament of void, and it's beautiful.
