Nested hotlinks in multiple projects

[GG_rakurs]

I have a series (4) of projects which are all separate in the administrative sense: each has its own plot and its own administrative process.

The projects share the same building and are positioned on four consecutive plots from north to south. Each plot has a difference of 1m in elevation, sloping from the northmost to the southmost.

I have created a module which represents the buliding only, I have another module for everything outside all four plots (road, neighbouring plots) and I have all four plots in separate files, so six files in total.

Since I cannot disable SOME modules from being loaded (it's either skip all or load all nested modules), what is the best way to not have an absolute cluster*** of loaded files and recursive loading? I am at a loss because no solution seems obvious to me. Do you have any suggestions?

The reason I'm loading them all in all four files is that I want the sections and elevations which go all the way through the plot and partially on the next one to have context. And I would like to have a site plan that has all four plots, in each of the four projects. I mean, I can toggle layers on and off - put nested modules onto project-specific layers so I can turn them on or off in individual files - but the modules are still being loaded recursively multiple tiimes and filling up memory.

If i skip nested modules, then I would need to put the "building" module manually three additional times for each outside plot in each project file. Is that really the best way to do it?

I would have a siteplan with masses only ,  one set for construction documents for that building and 4 first floor showing sidewalks, roads , etc ... The levels related - (level +0 )to the building and on the siteplan based on sea level per building equivalent to the level +0. 

 Because you are going to rotate the building (maybe) the names of the elevations should be generic instead of west, north, etc .
