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.

Look at Monument instead. Wallaby looks ok but I don't think it works so well with your brick.

(echoing others here) No, no, no NO! ............The issue isn't the brickwork nor the roof tiles.....rather it's the currently multicoloured trim of say your guttering, garage and windows etc... I'd also argue that the idea of the "award winning" example posted above, will most likely date in time.......although I like the landscaping aspect of that one - but otherwise it's too heavy tonally for my eye and the rear extension is a harsh juxtaposition formally........anyway,I digress.... On your home here I reckon you best to work within the inherent style rather than try and force it into something that it is not. Other things, some not that expensive, will go a long way here, for example, bring the trim colours into consistency, consider relocating the downpipe on the far left brick column, and focus on a proper front landscaping design (including removing the concrete aspect) and de-cluttering the verandah will also make a world of difference. Looks like you have a beautiful established (jacaranda) tree in your front yard - perhaps make that that the "hero" of your frontage / streetscape That's what I did on this project, whilst completely different style the point is it was more about the garden - the house and structure becomes supporting and complimentary to the external landscaped spaces Good luck!
