I'd go slate..if you're going to go light render..it will contrast nicely.. light roof tiles tends to date.. cloudpants the second house look gorgeous..

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.

Hi Pele - I hope you don't mind, but to my mind the thing that immediately jumps out at me as not fitting is the colour of the orange terrace tiles! The wall colour and roof colour seem in the earth/cool ochre range, and sort of complement the cool grey driveway even though they are different. The terrace tiles being bright orange clash! If you do/don't have the budget, I would prioritise painting or staining these tiles the Basalt colour which is a deeper grey like bluestone! Or even better switch your budget to retiling this area with a deeper grey or bluestone exterior tile. Add a few plant pots - and I love your timber garage door and possibly timber balustrade - and it would be dramatically transformed! I think this would be a better impact-for-dollar than painting the roof tiles which look to me to be in good condition. Good Luck!
