Great colour choices! I agree to go with the grey rug, but you can use the yellow as a subtle highlight colour in the design. Here is a photo of our Clover rug in grey and cream , but you could easily make the cream a light yellow. At Tsar we custom make rugs to the exact right size and colour combination to ensure you get it 100% right. Have a look at tsar.com.au. We'd be happy to assist.

My other bush of Rhodys, taken today, I'm on top of the steps, it's about 6 ft. I've cut them back each year, they were huge when I moved in. Not good to have huge bushes near the house if there's a bushfire. The first bush has finished flowering. It's a hotter pink.

guess you would have completed the update by now but just in case, They built great houses in the 70"s, a lot had concrete tiled roofs, have them checked and if sound paint them grey along with gutter and barge boards as you suggested but please do a soft grey otherwise it will look too top heavy, down pipes same colour as bricks (photo of soft grey roof) Paint garage doors same as brick colour minus the stripe, Front entrance update would help, does this open into a small foyer Railing, windows painted, I prefer black for this, I have attached a photo of a house that the owners had the roof painted, they painted all the metal windows themselves, said it was easy. Paving in front of entrance, this photo shows they used white pebbles and pavers with a small screen, plus a new hedge. similar entrance doors to these let in much needed light as these houses can be quite dark

We underplanted our ornamental pears with viburnum ‘Emerald lustre’ I just love this plant, it withstands all weather conditions and always looks great with shiny lush foliage, I would add a watering system so your trees and hedge don’t compete for water and it saves you time also.
