I think the main problem with this build is the discontinuity of the balconies where they meet these obvious shear walls.
The original design included radiator-style wrap-around end balconies, punctuated by the alternating diving-boards on the long faces. This is a more or less continuous balcony feature, with a nice mid-century hit on the end walls.
In the bastardization/cost saving process, these blank corner shear walls were added, which led to disruption in the rhythm of the balconies, and now our heads are exploding.
Even if they had gone with the cheapest possible material, the loss of the long balconies is a shame, in favour of cost over style.
You see, she's got rhythm:
