I think the structural challenges I may have in my project is mostly the height of my glulam beams. It can be a very good structural feature to design curved glulam columns for the exterior, or at least to design some curved beams to join the upper side of the exterior columns. I design a lot of beams for the floor slab and the roof for this project so there's not going to be a problem with that. My floor slab will be CLT over glulams so that will be lightweight compared to a concrete slab, resulting on a very seismic resistance structure. My biggest beam is 16.5M long as you can see below in case 2, but its 81" tall, and supports only dead loads form the roof and the beams itself.
I download from Rothoblaas's webpage some connectors and a stratigraphy design for a CLT floor slab. I will like to design the floor with that level of detail, mostly because that is the industry standard of CLT construction for tall wood buildings.
Regarding the HVAC, I insert a flexible duct to detailed the exposure that I want to have in the building, without gypsum board ceiling. My floor to floor height is 6 meters, so the HVAC space shouldn't be a problem.
