Can you photo shop your house white, for a true colour choice.
At the moment we are comparing your current facade with the garage door colour.

Good idea I’ll give that a go today

I think that you will ruin the classic look of your house by rendering.

I'll throw in a left-field idea . The problem IMO is the house has no highlight , and is a bit dark . Not that it needs rendering and modernising .

The front gate in Rust Treatment Red is wrong . The concrete drive is unloved . The existing garage door I gather is black . The terrace railing looks a grey , the barge board around the roof is black , gutters are black . There is no garden that can be seen , and the only colour is the bricks . Admittedly , a pretty meh shade , but its workable . Of course , you can cover and hide it , and spend $$$$$ , and change other colours , but you may end up shifting the problem , not solving it .

I'm flying blind a bit because there isn't a full street view , but heres some suggestions -- paint the front gate and presumably front fence in a metallic charcoal . Build a garden along just in side the fence line , with a range of heights and colours of plants -- even if you build it up 60-70cm from the concrete , and fill with soil .

Waterblast or chemically clean the concrete . Paint the gutter and barge board in white or grey or cream or similar to lighten the look 'upstairs' -- maybe even do the board and leave the gutter black . Minimise the heaviness of the roof .

Paint the upstairs balustrade/railing in charcoal . Put a couple of big ( 80cm tall x 60cm wide or bigger ) shiny bright Eygptian or Mediterranian pots on the upstairs terrace ( bright red or orange would be my choice , but blues or greens if you are shy haha ) , with leafy plants -- the pots can match , but use different heights and colours of plants .

Then , and only then , could you do a nice timber garage door , option a which is the 2nd picture looks nice and light , and a good match IMO .

There you go -- probably saved you the cost of rendering !

Don’t render. Paint everything that can be painted charcoal. Clean driveway. Add lots of landscaping and greenery.

Is there enough space between the windows on right for shutters? If you are painting the house white, then prob go with a grey that is picked up on gutters. Need to look at how hole picture of the future concept
