Hi again- I have been looking at Benjamin Moores colors and have chosen a few you might look at. My technique for color choices is to buy several large sheets of MDF from the hardware and several paint samples that I think will work. Grab a plain white sample pot as well and just play with colors; if what you thought looked good in the shop and doesn't look good in reality, just add a bit of the white to lighten it and use the darker tones to deepen. Once you've found the color you like paint it on one of the large MDF sheets and live with it for a day or two and see how it looks morning,night, south side of building,northside of building. If the color that you like is one that you've mixed yourself, just go back to the paintshop as I'm sure B Moore would have the right shade so you can match it. Do you know the color name of the roofing? Is it IRONSTONE or MONUMENT? I'd be tempted to use that same color for the windows. My personal trick for contrast and trims is to take the main color and ask paint shop to make it up in 1/4 strength even lighter if need be. Good luck and post pictures when it's finished.

We solve this issue with our clients all of the time with outdoor water features. We recommend getting a water wall that is suitable for both indoor and outdoor use. Not only will they drown out the noise but will also act as a nice privacy wall. https://www.soothingwalls.com/outdoor-fountains/glass-outdoor-fountains.html

If I had a small child, definitely. Plus, I use my bathtub for so much more than baths. It's also great for pet baths and other cleaning duties. I don't have a utility sink in my laundry, so maybe if I had a utility sink, I would not need the bath tub so much.

Get the professional sander guys in to repair the living areas and kitchen but don't go too dark with the stain as it will kill the lovely grain in the matai. I'm thinking a couple of tones richer than the timber knots showing in your photo, definitely no yellow tone at all. In NZ stepping on to carpet especially in a kiwi winter is so much nicer than a cold floor board shock!!! A nice area rug for the lounge and you're done.
