You have a lot of great features included that aren't replicated in modern houses due to costs. The semi circular stairs, thats wow right there! ^^petapea is spot on by the way! I'm currently working on plans for a house that was rendered in 2006. It has the wow factor; WOW that's bland as bat sh!t.... We're adding things like a bay window, new porch in painted timber and some masonry back to make it look good again. Then the new landscaping will really lift it! You could render garage facade and paint it, pressure clean the rest and do those maintenance jobs like cracked flooring, leaking gutters etc. The stairs are too narrow to be any use so widen them up to 1000-1200 wide. I'd spend more on landscaping (which includes fences/letter box/etc).

Congrats on choosing blocks for your garden bed. If you're looking for trees, I suggest considering a maple tree. They grow nicely over time, providing shade and privacy. I recently moved to a new house myself, and I'm also exploring plant options. Back in my hometown, we had a reliable tree service that helped us with planting and maintenance. Maybe you can find something similar in your area. I came across this website, https://www.deepdale-trees.co.uk , which might be helpful for you. They offer a variety of trees and services.

I would definitely remove the animal on the floor and cushions. And the Italian pedestal and floral display. Try the deer print on the black wall in the lounge area. Try it on the right hand side of wall at eye level, after you take the pedestal away. Put your tall table decoration onto the white buffet, where the deer was. Can you remove the shiny light fittings that are in the dining room space. They seem not to work. Install led down lights. As the existing lights seem not to be where you have your table. This is my opinion. Everyone's tastes are different.

I do love native violets but they show their best with some shade. For full sun a very rough forums cover with small white flowers is myoporum. The Gardening with Angus site has a great plant selector for other options. Good on you for looking at standard Lilly pilly - they give you greenery all year around unlike roses, weeping cherries etc.
