Gal will go grey (mid to dark grey) over 12 - 18 months. Initially VERY bright. The energy absorbed changes accordingly, from sub 5% absorbed to ~35%. Zinc maintains brightness for longer, though still suffers some dulling. Say 5% to 15% over time. This can be avoided by coating with a product called 'Sharkhide' metal protectant, used to stop aluminium boats oxidising. For there reasons many councils will not allow zinc or gal roofing (visual amenity, reflection issues), while making the houses more prone to requiring summer aircon at the same time. Surfmist Colorbond starts around 9% absorbed. If purely for energy reasons, a light colour might be the only option. If going dark, I would suggest at least doing the 'less aesthetically important' sides and rear in a light colour. Your call. If you go all dark, ensure you have good roof space ventilation for the summer that can be closed in the winter, and lots of well installed ceiling level insulation. Spray foam is more reliable over time than batts, see Spray It Solutions or similar (they have the Formaldahyde free Canadian Icenene foam).

The beautifully made bed - looks like a coin would bounce off it!! Simultaneously the view - I think the birdsong in the morning would be a wonderful way to wake up.

I agree with several other commentators. I love the look of your house, arches & all. Retro is in! I would pretty much leave as is & concentrate on cleaning concrete & landscaping. You will be amazed at what a difference good landscaping will make to the street appeal. With the right colors in your planting you might even come to like the look of your home like most of us already do. In a busy world the last thing you want is more upkeep & I think you would be making a rod for you own back if you render or paint the brick. And keeping it true to the era could add to its resale value. The only things I would change is the color of the garage doors & facia to either Dulux Natural White or Antique White USA whichever you prefer & the gates black if you want to be safe or a bolder contrasting color. As for the window frames I keep tossing up between the black & the white. Maybe black window frames with black gates would look good. Good luck with it all & look forward to seeing the finished result. Cheers Jenny

Beautiful work. Love the detail like the marble on the book shelves. I came across this in a search for how to put colour in a kitchen and this is a stunner. All the colours and textures are coordinated well - easy on the eye unlike some colourful kitchens. Love the wallpaper choice in laun and bathroom too. This kitchen seems to have come under fire for not being a cook's kitchen but it would work for me and I’ve been a pro cook in my life. That wide island is fabulous.
