had an idear - maybe stupid - but I was thinking about an modular tower (and more to place it in the city, not at the outskirts). The base structure was the building model, generic and always the same - only differ in heights - but the top is a prop and exchangeable.
So you could build up antenna parks or build tk-masts in your city with a variety. Don't know if this makes sense.
Abusing of the use of 'philosophically', I think that we could think on commercial buildings more as apparatuses or tools, and residential buildings as shelters. Those meanings have some graphic and physical correlates, so a business tower could look as a high-tech device, but not as a comfortable place to seek shelter from the outside; this was, anyway, less pronounced in older architectonical styles: up to early modernism (~1940s) or even brutalism (~1950s and 1960s) commercial and residential buildings looked similar and even were merged together, mainly because the idea of building as a shelter was stronger then.
With the development of the architectonical paradigm of shape separated from structure (and the technical methods to archieve that), newer commercial buildings begun to hide structural masses and to look more light, less 'protective', opening the aforementioned gap.
I think this couple of google images result pages explain this better than me:
