We have dulux whisper white cabinetry and it is lovely soft/warm but I made mistake of using non-tinted ceiling paint and even with bulkhead divide it looks too stark white (or makes cabinetry look too creamy). Since I can't change the cabinetry, I think I will eventually go over ceiling with 1/4 tint whisper white.

Just as a tip, those dark colours in your light brick arent' grey, they are a deep purple/brown also known as Burnt Umber. The midtone colour in that brick is also a purple brown in a natural mineral, in artists land that colour is called Indian Red, other similar hues are perylene maroon and piemontite. I'm an artist so very used to seeing different colours and their undertones. Colours that will go with that will be blacks that are actually red or purple based. So NOT monument which is a blue based charcoal. Blacks come in many different tones and it's important to match the undertone to your brick for colour harmony. Blacks which are complementary or blue based will stand out more but may not go as well. Which is why the grey blind seems uninspiring, it's a blue based grey. I'll name some colours in the Taubmans brand. I didn't pick Dulux because it has an abyssmal colour selection atm. Phantom Myst and Fable would both be good blacks to use on your home. Ruby Rose and Redwood and Russet stone would all go with the brick colours. Unless you train your eye to see hues and undertones it's very difficult to spot them which is why a colour consultants have a job. If you're interested learning colour mixing is fascinating there are even hues like red-blues which sounds paradoxical but ultramarine is actually a red based blue' A hack for creating colour palettes super easy. If you have Photoshop you can show it a photo and it will automatically create a perfectly co-ordinated colour palette for you of 6 or so colours which are exact matches to the colours in the photos. Any photo at all, and it will spit out pantone colour codes for you that you can take to paint shop and have them mix up. It picks up some dark, mid and light tones and you can have it create monochromatic, complementary, split coplementary etc palettes that work beautifully.

Siriuskey... Wow! All that red! Sorry, but I hate it. It's just too strong for me. Okay on somebody else's house, but I would very quickly tire of it. I like colours from nature. They are timeless. In answer to your questions, the wall on the right is the end of the terrace and definitely needed. Need not be a feature, of course, but I think it's nice to have something visually appealing edging the front terrace. The one on the left screens the front porch and creates separation from the lawn in front of the living areas. Both walls are under the roof, though the one on the right extends out just a little past the edge of the roof. I am looking at the frame now and I like it. I did have reservations, but it looks good. As for the ''stepped out'' wall - it's a little bay in the living room. Not really serving any purpose other than to add a little architectural interest, but I like it. No fireplace! The designer intended for a big TV to go in there but as we have a media room, I didn't want a television in that room, and I did want some windows to invite the north sun in the winter. It will either house the grandchildren's rocking horse or a little conversation setting of two small chairs and coffee table. I think it will look good from the outside with the feature paneling on it. From inside, it's definitely more interesting than just a straight wall. I'll post photos when it's nearer completion. It will make more sense when you can see a proper picture.

Hey there, I love the terracotta! I would paint the house a white with a warm grey undertone to freshen it up but compliment the warmth too, a deeper neutral white will achieve this. I would paint the surround a deep chestnut brown to highlight your plantings - gutters same colour. Put in a caramel accent, perhaps with a timber door, planted caramel pots by the door. I would carry the white over your trim, to highlight the garden rather than the posts and hand rail. This might not be quite the colour scheme you mentioned, but if you surround the terracotta with a monochromatic look (especially with cold or stark undertones), those tiles will be all you see! Best to work with them to calm them down - In my opinion :)
