This morning I went to the hardware shop and bought the base, sides and a few packs of wood for the structure oh and some screws. Totalling around £150 - not an insignificant amount of money, but as this will be the bulk of the trailer I didn't think it was too bad. I didn't buy the ply for the roof, that'll be another £30.
My budget for the total build is £300...
My woodworking skills are minimal at best, although I'm a "handy guy" the last time I did anything anywhere near this was at school - that project did not turn out well though! I'm hoping that common sense and the great wealth of information on this forum will see me through!
This is my plan, rough I know:

Anyway, back to the build. After collecting my supplies I set to pulling the old rotten floor off of the trailer including all the supports/joists which needed replacing:

After it was all clear, I offered up the fresh wood:

Trimmed them all to the correct size - note the extra length, although the trailer is 4' wide it was only 6' ish long so needed extending. Originally I was going to go forwards but decided to go rearwards to try and even out the weight as it was already a bit nose heavy.

Started adding cross-members, I did the middle section too but forgot to take a photo:

Lastly for the day I fitted the wall supports:

This will be double skinned with a basic framework between the skin, not really sure yet - will think about that tomorrow when I draw, cut and fit the side profiles. If I get time I'll fit the roof ribs, then next weekend the roof
