I think just removing the wallpaper and and painting (instead of adding more wallpaper) would make a big difference (particularly in the bathroom). Also, I would get rid of the current mirror in the bathroom and replace with a smaller framed type, paint the cabinet and new hardware. Honestly, I think just paint will make a world of difference in your space.

What a fantastic architecture. When you do the brick, if you stain it with masonry /concrete stain you won't have the same issues of maintenance as with paint. They will spray it evenly - through you will have to select a deeper color - either taupe (brown-gray) or a straight charcoal. Love your windows and the classic angled railing. I think a dark gray on the siding will make the orange brick jump even more. What bothers me is the white (railing, fascia, eaves) juxtaposed with the earth toned stuff. So I would recommend camel tones - for the siding - something like http://www.sherwin-williams.com/homeowners/color/find-and-explore-colors/paint-colors-by-family/SW6108-latte/ and the hopsack next darker tone for the garage door. Use the lighter tan for trim that is now white - http://www.sherwin-williams.com/homeowners/color/find-and-explore-colors/paint-colors-by-family/SW6107-nomadic-desert/ Use the darkest tone if you are painting concrete steps. If you think you will stain your brick charcoal, then the white eaves and trim are probably right, and you may not want to paint it tan now and then go back. If your brick were charcoal, then I would block out the rest in grays and blue grays - leave the white eaves, but take the railing and posts charcoal too. A blue gray door - like sw smoky blue.

The setting is quite tropical, so a darker scheme with white trims has such a tropical holiday feel. You may consider using a concrete face brick for the lower section. This will be modern, and eliminate the need for painting, while still creating contrast with the upper level. Try a colour for the main house like Resene Evolution, or Quarter Evolution, both would be perfect for your style of home. The colour scheme that we recommend for you is our Rainforest Board which includes everything you need to bring the look together! https://www.bodoboards.com.au/collections/paint-concept/products/rainforest-paint-concept We would love to see updates as you go.. its going to be great!

First of all I would like to say it looks like your parents have brought a lovely looking home. The colouring of the outside of the house it typical for it's age. I would like to suggest that you stick with a light tone for the outside but is the Yellow / Cream isn't working then perhaps consider going for a White with a tiny tint of pale green .... this will blend in nicely with the garden, window joinery and roof but it will not be stark white. Internally I am a bit of a cream on cream kind of a person because I like to add colour through my furnishings, knick-knacks etc but I have to say I did move into a home with a mint green carpet which suits my personality but is not all together practical with pets coming and going and a lounge painted a medium to dark mint and I really love that colour. Originally the hall ways and other room where a butter / cream and just making it a off white really boosted the light and spaciousness of the home. The lounge is still the same minty green and I think I will repaint it a similar colour as it is very relaxing and "natural". So go for something that is restful inside and something clean and almost white outside. Hope that helps.
