A white interior is classic and envokes a s ense of spaciousness, freshness and luxury. However, using all white wihtout knowing what makes white interiors work is tricky starting from scratch. The insiders tip is to build upon many shades of it with as much neutral based whites as possible. Use warmer shades on larger areas such as walls, and then layer with tactile surfaces in the form of fabrics, rugs, and upholstery. Tones and textures in this natural colour scale will unify it and help the key accent items come to life amongst a white space. Mostly, when we refer to a 'white' interior, it's actually referring to how it feels as opposed to the colour- or lack of one. Think of a a grey scale, starting from white, and shades of grey right up to black, this is what you need to do, replacing the black at the top of the grey scale with your version of a natural white, taupe, beige, griege or whatever your chosen warmest shade of white is. For some it's right up there at caramel, yours migt be a stone colour, then work backwards incorporating these shades and tones of white using key pieces to Soften or invigorate the space. As you build upon this, it will start coming together, and in fact, the more you do, the better it will become. Picture for example, a Sisal rug which is a natural rope colour, then a linen sofa in a warm white calico, with a cashmere cream throw and rich, ivory blended cushions, in velvet or tactile fabrics. Use glass, reflective elements or metallic furniture where fabric is not possible, like reflective mirror to reinforce the sense of light that white evokes, coppers, burnished bronzes or even polished metals in coffee tables, lamp bases and accent pieces. Lighting will make a huge contribution to this layering, casting (warm)beige shadows over your white room by evening. this is called 'ambience'. Start collecting your white swatches, and lay them out collecting tones you like along with fabrics etc. It will come together, just select your key pieces (expensses) like sofas and rugs first in your fave shade of white, then be bold with pillows, scatter,s lampshades and the rest. Have fun!

I notice you have an aluminium screen door. Are the window frames aluminium as well? If so, you can re-paint them using a bonding substance called ESP. This is a link to Bunnings spray version but it also comes in a liquid you can wipe on and off: https://www.bunnings.com.au/flood-300g-esp-surface-prep-spray_p1560212 It's pretty easy once you get used to removing the screen and re-installing it (makes overpainting go away). It means that the paint won't chip off if someone knocks it which usually happens with aluminium and some other surfaces. Answering your questions, if you make the entrance lighter you may not need to make the walls either side lighter. I like dark - it is very dramatic and not as common. If you start with the entrance you can stand back and look at how it goes with the other walls. Also remember they don't all have to be the same. Variation in colour and texture adds interest, just make sure it doesn't look too busy and all the surfaces blend (not necessarily match). Your back wall is plain and straight, so regardless of the colour you end up choosing it will need to be augmented with something. You could try a large mirror on the blank space between windows. Something with a chunky frame in a contrasting colour and you will have a reflection of the greenery opposite. You could also try a reclaimed timber feature or something rusty or possibly a small timber pergola over the back door (similar colour to the window frames) that will give some depth. It's only paint, so try using patches with sample pots before you put too much effort into painting all the walls. Good luck.

I'd go a paler wood personally. But given the choice of surfmist or dune....surfmist all the way!

Perhaps a dark paint on the lower band of brickwork to anchor the house and tie in the dark window frames and door. Can make a big visual difference and if you use a good quality paint is easy and not that expensive. Lasts really well as the brick is rough. Woodland grey would anchor and blend and has a recessive effect as well. Monument is probably too dark. Scrub or power wash the grey drive to bring it back up if possible. Also agree with others about a darker green to tie down the railings lower trim and posts.
