if the original asbestos walls are in good condition then they can re-be painted but if the walls are too damaged to be saved the asbestos needs to be removed by professionals and the cladding replaced, no reason you can't have different profiles on the front and sides as long as joints and corners are sealed properly but if you plan to install new windows it could be better to wait to repair sections of wall as the windows are replaced (i'd prefer to have all the roof and external walls in good condition and then do the internal work at leisure)... .modern fibrous cements are excellent ...we've just used flat fibrous cement with curved battens over joints and very happy with the results for our 50's house (there are several different brands available through the big hardware stores and research on line is much easier than trying to work out the variations in store) the gabled portico can be made as a separate structure or as a extension to the roof with valley gutters depending on placement of the solar panels (and/or solar panels can be moved)

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 !

asked B&D and Gliderol .... they said, you can have any colour that you like, as long as its grey! ha! I was thinking maybe a roller door will just look poor when exposed in an outdoor setting (with other beautiful landscaping making it look shabby and out of place) ....looking for a photo to prove me wrong.
