There was a lot of work to do, and with a fully closed shed with 5m high walls, no windows, there was very limited light to start building the floor, so the first step was to cut a hole in a wall and fit the first window.
I purchased a secondhand, awning opening, double aluminium window for around $200.
I had basic tools, and put the angle grinder to good use, after lifting the window from floor to upper level height with the block and tackle, then worked out where to put the window, add cross timbers to support the window and wall opening.
Then it was lower the window out of the way, cut the hole, and being fine weather, there wasn’t too much pressure to get it fitted in the one day, but I managed to cut the hole, place the window and get it secured with timbers across top and bottom, then sides.
