Ok are we talking architectural designer or interior designer? Architects are more about lines and form and they grumble about the interior designers but that's who they hire to do the color boards. Either way you are the client and it's your house. It may be a great color scheme for the design but if you don't like it change it. Those sample of paint are worth every penny because you need to see more than a little chip. With your asymmetrical design you have room to vary more than the usual field or base color and a contrasting trim. I'd make a tracing of the design and copy a bunch of pages of it to use as a coloring book. (yes use crayolas:-) Another shade from the same shale grey paint chip and a one more accent color would be a good bet. If you are going subtle neutral, make it 3( not 50) shades of grey and play with where you put the darks and lights. Remember sunlight and shadows will create alot of contrast for even a "pale monochrome houses. (the computer rendering doesn't give you that.) You could add a pop a smoky teal, plum or coral if you want color as bold as you design. These would just be accents or trim. If shale grey it a really light silver you could make a monochromatic scheme with blue grays and a navy blue door and trim. The tan/beige in the rendering needs a darker grey to work. I would keep my midtone color on the lower level and a lighter shade on the second level. The top part that pop out could be a bolder accent color withe rest of the upper level almost white. Lot depends on your roof and window frames and whether you want them to blend in or pop out. Try a bunch out on paper or one of the computer programs before choosing any changes.

It's a neat concept, but highly impractical for a wet, coastal climate of BC where I live. We could only have the wall open for roughly 4 months out of the year. And those open months would need a screen, big time. I'd forever be the one to be walking into the screen, which would bug the heck out of me (pun, lol), so I'll just pass on the whole idea. It's like the convertible car owners up here. We'll get a nice, sunny day in winter and you will see these people with their tops down, but wearing toques, lol. Or they will take the top down on the first sunny morning in spring and by afternoon it's pouring rain, again. Convertible in BC? Extremely seasonal. Convertible wall in BC? Ditto.

Before replacing your curtains as this can be quite expensive for such a large window, if they are in good condition, add a band of extra fabric to the bottom in what ever suits you, your existing curtain track can then be moved up to the ceiling for good looking full length curtains without the large round eyelets, could save you a lot of money, I would look at replacing/removing the sheers cheers

We have been building our house for over two years now. The supply chain downturn has made it a nightmare. We are camping on the mezzanine floor of our warehouse so it isn't costing us to wait, but if I had rented a property while building we would be in trouble now. I purchased most of our plumbing supplies early in the build so at least those items have not gone up in price, but many others have. We ordered and paid for a cantilever pool awning in February this year, and it was sent in three lots. The last delivery was two weeks ago. I suspect the company was having a hard time getting it out of China, so not their fault. We had quotes for fly screens/security screens that totalled over $25,000. We had to forgo the security screens in favour of fly screens for most of the house. We had a quote for a large aluminium mesh panel to place on the front left corner of the house which was over $25,000 also. The fencing company got an order wrong and we ended up with the wrong colour louvre panels on the front driveway sliding gates, plus the wrong colour for a fence. We have managed to turn it into a positive by keeping the wrong coloured louvre blades, and they will now be put up vertically on the front corner of the house, instead of the aluminium mesh. They are six metres long, but the house is two stories, so all good. We had to keep the gate panels the same, so the wrong colour will have to be exchanged for the right colour. People are still building houses here, and some of them are going up very fast, so I don't understand why ours has taken so long. We have purchased most of the goods locally, but I suppose the suppliers are having trouble getting them from overseas. I am at the point where I am losing interest in this house, which is a shame because it will be a beautiful house when finished.
