These are photos of the stairwell in glacier grey. I tried to take photos going up the stairwell. This is in a house that we just sold, so things are moved and missing. As you can see the colour changes in the different light. I tried to show you how I started at the ground floor and followed the same colour up to the 3 rd floor. The other colour is Dulux Whisper white. This is not Besser Block but honestly you can paint Besser block in whatever colour you think will suit the walls. As I said I used whisper white and a charcoal, feature wall. different house. Looking at your photos I would probably suggest the Glacier grey with the whisper white and white railings. Hope the photos help.

You could have the Sherwin colours mixed in Dulux, Wattyl, etc. if you're still unsure of quality. Painting is expensive as it's labour intensive yet the material part is relatively cheap so buy a quality brand you trust rather the cheaper one. I'd always buy Australian made as it's be formulated for our our climate and keeps locals in jobs.

You have some great space their for an amazing landscape. It really depends on the style you are after. There are a few that will work with the house! The picture posted above is a great example of a planted out native front garden, or you could go for more of a Palm Springs style with feature curved beds at the points of the lawn while keeping the turf through the middle. This would work well with succulents and great architectural planting. The horizontal lines of your home even lend themselves towards a Japanes inspired garden. You can perfectly frame your house with some beautiful Japanese Maples and underplant with soft foliage plants such as Acacia cognata 'Limelight'. It does depend on your climate and aspect, however so be mindful of where the hot sun might be! Here are some ideas on finding your style to suit your home: https://australianmodernistlandscapes.com/2016/05/27/establishing-your-style/ All the best with your project!

I would take the shutters off and see how it looks. And yes to painting them if they are to go back up, paint the windows, the existing painted parts of the porch, gate and the gable all the same warm white colour. The fascia and gutter a warm grey like woodland grey. Some flowering plants will complete the brightening up. You can mKe the whole gable darker, say a 1/4 strength of gutter.
