         5 . Building unit according to  claim 4 , characterised in that said poles ( 42 ) are tubular and their lower ends fit onto said end-pieces ( 38 ).  
     
     
         6 . Building unit according to  claim 5 , characterised in that the upper ends of said poles ( 42 ) are fitted with end-pieces ( 44 ) which are inserted in openings made in the four corners of the upper frame.  
     
     
         7 . Building unit according to  claim 6 , characterised in that it includes, moreover: 
 four new walls ( 34 ) set on the vertical members of the upper frame, which becomes an intermediate frame;    a new upper frame ( 20 ) identical to the first two, the vertical members of which rest on said walls, and    four new poles ( 42 ) which are arranged in pairs, one at the front and the other at the rear, outside the walls and connecting the intermediate frame and the upper frame together by their corners.    
     
     
         8 . Building unit according to  claim 7 , characterised in that the four new poles ( 42 ) are tubular and their lower ends fit onto the end-pieces ( 44 ) of the four lower poles.  
     
     
         9 . Building unit according to one of the  claims 1  to  8 , characterised in that it includes a slab ( 32   a ) arranged inside each of said frames.  
     
     
         10 . Building unit according to one of the  claims 1  to  8 , characterised in that the vertical members of said frames ( 20 ) are sections having an external horizontal portion ( 24 ) on which rest said walls and an internal horizontal portion ( 26 ) on which rest the edges of said slabs.  
     
     
         11 . Building unit according to one of the  claims 1  to  10 , characterised in that it includes a roof consisting of a bar ( 50 ) connecting the upper ends of the two rear poles, a bar ( 50 ) connecting the ends of the two front poles, a third intermediate bar ( 56 ) parallel to the first two, raised above them and carried by the upper frame, and a tarpaulin ( 58 ) placed on said bars.  
     
     
         12 . Building unit according to one of the  claims 2  to  10 , characterised in that the chassis ( 12 ) is extended, at the front, beyond the lower frame, and in that it also includes two external access balcony poles ( 46 ) attached at its end.  
     
     
         13 . Building unit according to  claim 12 , characterised in that it includes a roof consisting of a bar ( 50 ) connecting the upper ends of the two rear poles, a bar ( 50 ) connecting the ends of the two external access balcony poles, a third intermediate bar ( 56 ) parallel to the first two, raised above them and carried by the upper frame, and a tarpaulin ( 58 ) placed on said bars.  
     
     
         14 . Building unit according to one of the claims  11  and  13 , characterised in that the tarpaulin is attached to the first two bars by means ( 48 ) allowing it to be stretched.
