The most recent work involved considerable tweaking and testing to get the roof to roll off correctly. The roof works by rolling on casters and there are counterweights to make it move easily. This was completed on Wednesday and Thursday. The only change still needed is to replace the weights (cement bricks) with something a little heavier. It's easy to move the roof down but requires a good tug to get it back up again.
Also on Thursday the electrician was here to dig a trench and install the electrical service to the building along with a data cable for my Internet connectivity.
