We are discussing support for a new EPSG code (probably going to be EPSG:-1
or EPSG:9999) designed for this very use case
on Geotools devel.
For the moment just associate your data with whatever projected SRS having a
large domain of valid coordinates, don't use EPSG:4326, but maybe
ESPG:900913.
For the treatment of the floor, do you have an attribute in your data
indicating what the floor is? If so you can apply a CQL filter
to select the floor to be displayed.
Otherwise I guess you can have one separate WMS layer per floor.
Hope this helps
Cheers
