Congrats!!
I'm no accountant but I'm not sure I understand your theory with putting that money into PPOR and then withdrawing for development. Can you please run the ideas by your accountant to make sure you do it the most effective way.
yes I think you've added value.
From my perspective the next cosmetic things I'd do would be to get rid of the green on the elevation and replace it with a grey/charcoal and paint/seal the driveway.
