Sorry about the delay posting more on this build.  Real life being what it is put this on
hold.  Back to business.  
Once the windows are built I usually start on the floor to
create the footprint for the building.  Here
I am using Hirst arts tiles and blocks for parts of this build.  I glued the tiles together face down on a
cutting board so I had a level floor. 
Once I glued it down I reinforced the back with more glue and then some
putty on the portions of the tiles that were not level for added stability.  When the floor was completely set I turned it
over and filled all gaps between the tiles. 
 
Next I again use the Hirst blocks to build the bottom edge
of the walls and corners of the building. 
After these parts dry I roughly cut foam core walls to fill the open
areas and roughly set the windows.  You
will notice lots of gaps here as I did not worry too much about the fit since I
will be covering the walls inside and out and I was in a bit of a hurry at the time. The windows are
shimmed in and leveled with coffee stirrers.  When the walls are set in place I cap them with popsicle
sticks so I have a level surface to put the roof on and to edge the façade for
the exterior walls.   
After gluing the popsicle sticks on I use coffee stirrers to
fill any gaps between the foam core, wood and Hirst blocks.  
 When I have a good surface for the wall faces, I cover the
whole wall with PVA glue and then dump clay kitty litter onto the surface.  This will appear similar to a flint
nodule surface.  After the PVA sets up I use
super glue dribbled over the surface to protect the kitty litter with a hard
acrylic surface and to set it firmly in place.  
 
Hope you like.
