Yes, our harsh Australian environment does hammer our external finishes but if exposed timber is coated with a good quality finish initially ( i recommend 4 coats minimum ) then an ongoing maintenance coat every couple of years, your timber can still look great many years down the track. People just need to understand if you want that beautiful natural timber look you have to put time in to maintain it.

I think if you replace front door and glass panels as well as the old fashioned lights with something more contemporary it will make a huge improvement. I'd also remove the ironwork and as you cannot re-glaze place some pots and plants on the sides of the large windows to draw the eye away from all the green cross pieces on the windows. Eventually paint the gutters fascia in a light grey/green.

The silver will look quite good with your colour scheme. I would probably change some weatherboard for Scyon Axon just to change it up a bit. Also use Scyon Axent for architraves and wall corners. Don't forget eaves and veranda ceilings, etc. as a really nice looking feature use HardieGroove or maybe even some timber to break up the acres of painted surfaces.

looks good... it could be timber or an aluminium cladding like UltraClad why don't you knock on the door and ask one of the tradies or phone the builder it looks like the number is on the pink sign?
