Apart from the paint colour there are a few other things I would change first. Are you able to change the vertical blinds? They are contributing to the dated look. I would lose the table clothes completely and get some modern art for your walls. The lighting is also something I would look at changing especially the ceiling pendant ( too traditional) and the floor lamp. I would also get rid of half the sofa cushions. Changing the paint colour alone will not make your place look modern, IMHO.

Hi L Shum. I think it depends on the style and colour/s of your house, whether it's brick, weatherboard, or other cladding, and where the planters will be placed in relation to it. ?? Not knowing this, I'll suggest there are lots of warmer whites you might like to sample: Antique White USA, Natural White, White Duck, White Duck Quarter....

With such a large house I think it would need some other darker colour along with white to help "ground" the look. Also, as mentioned above, pure white on an exterior looks very glarey - surfmist would be perfect. I would strongly suggest getting a colour consultant to help with such a large project - and get some mock-ups done with different colour ideas.

It is impossible to say without seeing the unit and understanding the natural light and the other colours. I would check out this link from Dulux, then run down to Bunnings to get some samples. https://www.dulux.com.au/colour/whites-and-neutrals/most-loved.html Dulux Vivid White always works well on 1960's trims and doors, but it would be too clinical for walls.
