The transparency part is quite easy if your structural elements are in separate layers to your architectural elements.
If so you can just make the layers for the architectural elements wire frame in the layers settings dialogue.
This can be set as wire frame or solid in different layer combinations so it is very easy to switch between solid or wireframe.
As for the colour you could set the surface material for all structural elements to a material that has the appearance that you want.
However once set it will be the same always unless you manually change the surface material again.
But you might be able to use the renovation filters if you are not using them for their intended purpose.
Set all structural elements as either 'new', 'existing' or ' to be demolished' and make sure all other elements are set to one of the other reno states.
Then make sure your reno filters show all reno states but over-ride the surface colour of your structural elements (i.e. the 'new' reno state if you used that).
Now by changing the reno filter being used you can alter the appearance of the materials and together with the layer combinations you can control the wire frame/solid appearance.
I hope this is correct as I don't usually use the reno filters but I am pretty sure they can be used for this purpose if you are not using them for their intended purpose.
Of course this assumes you are using version 15 or above which has the renovation filters.
