I see the point along the promenade architecturale [in Le Corbusier's Villa Savoye and his Palais des Congrès] where there is both outside and inside as precisely the same as Terragni's representation of Purgatory within the Danteum--the room that manifests equal measures of inside and outside. When I was a child in Catholic school, Purgatory was often described as 'limbo'--essentially being there and not there at the same time. The notion of limbo basically differs, however, from the notion of purgation. Purgatory gets its name because that is where purging (of the profane from the sacred) occurs. This notion of separation also relates directly to the notion bifurcation that you related to the heart of the Villa Savoye.
The notion of limbo also directly describes the inside/outside ramp situation of the Palais des Congrès--not only is the ramp 'suspended' (in limbo) outside the main building block, moreover, half way up the ramp, it changes from an interior ramp to an exterior ramp.
...we will find ourselves on the roof, in the solarium, in Paradiso, within 'the sacred' as our present... ...comes to an end.
Being now in limbo (at the half-way point), however, we have the opportunity to venture/explore within both the profane and sacred realms.
Re: genetic architecture
The forms don't bother me, and the method (i.e. using CAD, etc. software) doesn't bother me. What I think is wrong, however, is the hype, specifically, in this case, that all this is somewhat more authentic because it is more natural, more 'genetic' and therefore more correct. Where, in reality, it is all just more arbitrary.
I remember back in school where there had to be a reason for ones design, and the worst thing possible to be criticized for was for being arbitrary. I more or less had to comply then, but I know better now--for example, I venture to guess that most architectural clients are almost fully arbitrary, as is almost all of the architecture being built today--how else would you explain the way things really look out there.
arbitrary 1: depending on choice or discretion; specif : determined by decision of a judge or tribunal rather than defined by statute 2 a (1) : arising from unrestrained exercise of the will, caprice, or personal preference : given to expressing opinions that arise thus (2) : selected at random or as a typical example b : based on random or convenient selection or choice rather than on reason or nature 3 a : given to willful irrational choices and demands : IMPERIOUS : characterized by absolute power or authority : DESPOTIC, TYRANNICAL
There really are no statutes of architectural design, except for building codes, and even they are not beyond being side-stepped, and there certainly is no definitive common ground as to what is good design and what good design isn't. So-called 'Genetic Architecture' is no better or worst an any other architecture available; right now it's just more trendy.
Teaching designers/architects (how) to be arbitrary might just be the real natural, rational thing.
