When you render the bricks I would consider leaving some of them exposed here and there - that reminds me of old Tuscan buildings! I would include some large terracotta pots with olive trees or lemon trees, also as others have suggested some brightly coloured geraniums in hanging baskets against the wall or in terra cotta pots. Here are a couple of shots of my back deck (which isn't looking its absolute best) but to give you an idea of the large pots and colour. You have a beautiful spot to work with good luck! Sue

Restore the facade. Don't render as you'll loose the fabulous brickwork. Just re-point it. Do maintenance on the roof as needed. I'd pressure clean then see what it comes up like. If it's still a bit ordinary then paint it. I would do a bit of investigating on other original colour schemes before choosing charcoal, even though I admit the charcoal does look really good! By the way we render as we don't want to pay brickies to really use their craft so we buy cheap bricks and render. Render does look fine when used as a feature rather than a whole facade. Don't compete with neighbours make your house more desirable by keeping its character. I would however consider spending some good money on the landscaping. There are some superb gardens on these wonderful homes around the inner suburbs of Melbourne for example and would work great with yours.

The roof is in good nick and being green probably fits in with the surrounding trees. It just needs a bit of modernising, which I don't think you will get with the Paper Bark. The following image shows a 'soft' colourscheme which you can imagine with your green roof, having very pale grey-green walls, off-white architraves, darker green shutters and charcoal door. Now check out the following colour mixes that also keep in mind your roof colour. I hope this helps.

What about one of these for roof and deck railings? Trial any colour using sample pots before you commit to purchase, as how the colour look can certainly vary. If if you are hiring a painter for the roof, the downspouts could be done at same time. I would not attempt to paint the spouting myself for reason you mentioned. Otherwise, leave them as is - as lush as your garden is, they may not be noticeable. As for your decking, is it painted? If so, I’m pretty sure you cannot oil it, so could either leave it to weather or repaint it.
