Enjoying flooring..

I have finally got some space in this workshop of mine, the platform I used as a flat surface to build the side panels on has now gone and I am a woodworker again.
  I have moved the trailer out into the space a little so I can get all the way around it and jacked it up level on its stabilisers,  feels really steady now.
   Then. This afternoon I started to really enjoy myself,  I finished cutting and laying the underfloor insulation and started laying the floor.  This feels like a major step forwards..
