Overhauling and Structure

The material palette I wish to utilize remains much the same as the interim, but I now have a more refined facade resolution.

Dealing with structure I have looked at the St Mary Axe Foster precedent and have fiddled a bit with my floor plans, but am leaving them be until I finalize the positions of the sheer walls which will dictate the new unit dimensions along with the beams. With that said I am looking at some alternatives and need a little bit of clarifications on the limitation of the systems at my disposal. Which is a result of the following explorations.

The above two drawings describe an alternative system with hss columns and long diagonal members which would run through multiple floors which would relieve the shear. Further I'm wondering whether or not I can have vertical members in this set up. instead of the diagonal ones foster uses in the facade because it is imperative I retain the vertical quality that relates back to my idea of the privacy gradient and deliniation of spaces as such. The diagonal elements are remnants of a printout of the model I made please overlook them for this scenario.

This illustration is fairly self explanatory. I have stuck to the shear walls capped with hss beams and supported by another set welded perpendicular to those. I understand that foster accomplished an unobstructed floor plate with his design but as appealing as the idea is it seems out of reach due to the nature of my form and relationship to the buildings next to me.

the decision to utilize hss is coming from the fact that I wish to expose my ceilings even in the residential levels to provide a more industrial yet clean aesthetic and as a system to deal with cables for the DMZ. I am also looking into a raised floor system to distribute utilities.
