Not sure where you're located, but a gravel driveway may help to soften the house versus asphalt or concrete. Soften up the area with grasses. Here's a link to a photo of grasses with a hot color palette http://www.spacemakerpress.com/catalogue/catimages/st05imgb.jpg You can always choose a more muted color palette as well. I would definitely tier the plan heights so they're taller against the house and gradually get lower. It would help to bring the house to human scale and not appear towering above. The pathway could be in a natural stone - the same color as the gravel driveway (if you can do gravel).

I think your layout is generally good. With a one bedroom it's nice for guests to have access to the ensuite without having to walk through the bedroom. One thing I do notice though is that there is a lot of hallway/storage/circulation space in the center of the building (in the two bedroom portion) that might be better used as living space. You could pretty easily make the ensuite in the one bedroom larger for example. The wash house space seems unnecessarily large to me as well. You could push the wall dividing kitchen from wash house almost all the way back to where the toilet door is in this plan (you'd then have the toilet door open into the wash room to the right from this viewpoint rather than straight ahead). This would leave much more kitchen to porch access, which would be nice.

Thanks Susan. I would love to get feedback here from the Houzz community on butterfly roof construction. I know that flashing the valley will be critical to say the least. Whoever does the roof has to have 1. Skill 3. Architectural specs to follow 2. Guaranteed work. How do they hold up in a climate such as yours which is sub-tropical? It's a big project so you will need to be confident in the outcome.

I would research the heck out of construction techniques so as to be as informed as possible so that you are able to have a better dialog with the roofer when the time comes http://www.builderbill-diy-help.com/box-gutter.html

Your layout for you kitchen looks really good and would fit well with the mixture of black and white cabinetry. With the lament bench top, we would suggest melamine (entry level cabinetry) or acrylic bench top, which can come in high gloss feature or matt. The matt surface would go lovely with your choice of bench top, and acrylic is also a affordable cabinetry material. Below are some examples of how Reno4u has incorporated both black and white cabinetry together, without making it to dominantly dark. We feel as if these examples would be perfect for your layout, and depending on if you want more black cabinetry or white you can go either way. This design above is an example with more black than white, can be made matt or gloss with different handles/splash back and wallpaper. With a u shaped kitchen similar to yours, however from the pictures you provided your style may include different design below the island bench. Another kitchen designed by us which shows more white than black, with a bar built in which may suit your design better. We hope this helps you, please feel free to call us on 03 423 9067 and we can provide a free quote for materials and kitchen design, and help you finalise your design further. :)
