Thanks for you opinion, Judy! I will ask colour selection consultant whether I can get the same colour of WIP door as joinery doors once I hear from the builder. It has been hard to reach them lately lol

Thanks bigreader for your advise. Whites are SO HARD. I have done a test patch with the Casper white half and fear it is too grey/green and too modern. The rest of the house is more warm white tones and the floor boards are warm. Confusing as the laminex bench top has grey tones and the splashback is navy? Leaning now more towards Snowy Mountains Half or Natural White - but what about trims??? Really trying to avoid the yellowish/old look that warm whites can throw as half done the bedrooms trims and doors in Antique White and they look old/tired already after 3 years. thanks for your time

Dulux whisper white. Get a sample pot, paint a large piece of cardboard and see for yourself.

To Modernise this without rendering or retiling the roof I would probably recommend to go darker with the trims. My top pick as a colour consultant would be Dulux's Domino for the trim. It will be a little bolder and create a more modern contemporary feel. You can see it pictured below as the trim. Obviously this house has painted their bricks in the shade "teahouse" however it will still look much better on your 1980s "peru" colour bricks! Don't hesitate to contact me if you need any more help colour wise!
