Missed opportunity Nige
mezzanine floor lol
When I built my shed it was a kit shed (Tristeel) I ordered it with a extra 1m in height its 7.5m x 6.5m with a wide sliding door at the front (7.5 side) so the front door is 1/2 of the front side when open, then I built the workbenches out of 40x40 RHS 5mm wall steel, I was the steel cutter at work at the time lol and 1/4 of my shed I built a mezzanine floor at my head height without hitting my head on the beams using steel I got and wood timber trusses from the old roof from next door when they built another level on top of their house, I am a scranger and don't like waste, it was all hard wood roof trusses and I also got the flooring from work
the good thing with a mezzanine floors it hides all the junk and storage for everything, the slot car track is under the mezzanine floor and also have storage under the slot car table.
I also over the years acquired 100mm wide steel C channel 3 lenghts at 9m long from work as well I bought 4 lenghts at 6m long when it was on special when buying steel for new house stumps at the time, the C channel sat untouched for about 12 years beside my shed and 2 years ago I built a 7.5m x 4m open awning off the front of my shed only had to pay for the new roofing iron and I mixed the concrete all by hand with a mixer so concrete, gravel and a new roofing iron all done for about $1k, did the mixing, pouring and screeting myself in 3 stages, that's where the snooker table is now as well the table and chairs as well open work area when it gets to hot in the shed during the day, we get good sea breezes here as not far from Moreton Bay.
You can never have to much room as you always find things to fill up the space, my shed workshop is all about the bikes and can't even get a car up to my shed even if I wanted to lol.
FE your workshop looking good, to clean for me but then my shed was built in 1991 and there is always room for improvements, as for new bikes I am down sizing my collection of bikes 4 is enough but thinking of selling the dirt bike and the project Norton build has been sitting to long it might go to the next swap meet and see what I can get for it and just keep my Hotrod Norton and the 1200 Thruxton.
