Is there a logical way to distribute the termination?  You might be able 
to get better performance (not that you perhaps care, in this case) at 
minimal additional cost if you can do building-local termination of each 
customer circuit and then backhaul on e.g. bonded VDSL2 or G.FAST over 
shorter distances (perhaps hopping building to building).

I'm assuming there's no data grade copper or fiber if there's no coax. 
Obviously if you've got those, distributed termination makes even more 
sense.

If you do want a centralized solution, an Adtran TA5006 (the small 
chassis) with 6x 48 port VDSL2 combo modules (with or without vectoring, 
depending on your needs) would do the job (though it fills the chassis 
and doesn't allow for expansion, so the full-size TA5000 may be 
desirable).  I've played (and am playing with) the same system but with 
GPON termination and have been happy with it so far.
