Also some side views... first image is the sunny side, second image is the dark side. Some of the windows are high to prevent overlooking into neighbouring properties (by regulation).

How exciting on your new build! I believe the exterior colour choices are beautiful and will compliment each other nicely. I would consider a different type of feature wall in the middle as the one you currently have looks a bit out of place. Maybe the brick at the bottom, or stone? In regards to the windows it probably looks funny because they are floor to ceiling windows (by the looks of it) I wouldn't change the types of windows, apart from the size. If your engineering allows you too, make them more centred in the wall. Hope this helps. If you would like some more advice please feel free to contact me by email!

Thank you very much for your feedback. Is this what you meant about centering the windows? The symmetry is a bit skewed because the top walls are 2.7m wide on the left and 3.4m wide on the right, with the windows both at 1.2m wide. I agree the windows look better when not floor-to-ceiling, especially in contrast with the feature panel.

If you're referring to centering of windows in the side view, my problem is that the interior is open plan and divided into kitchen/dining/living. There's also some articulation which is hard to see.

I posted here because I wasn't able to attach an image on the email contact form, but happy to continue on email. Thanks, Paul.

No Worries, happy to help! That is what i meant about centering the windows. I could see that one wall was bigger than the other, and i think because the windows were floor to ceiling that aspect was more prominent. In regards to centering the window, I was not talking about the side view, only the front view. I think that your side windows are good, and they will easily light up the rooms, as well as obscure your view of neighbors. Hope everything goes well!

you have very large windows just be sure to calculate heat loss and gain as well since the larger the window the more the heat transfer unless you are into double glazing

The top panel looks off centre to bottom door Is this so

I also agree you windows work together quite well, although I do see your concern from ground floor and first floor. I think it's a matter of proportions.
I thi k this style of architecture is best complimented by elongating the details, in particular windows under eave line. In your case, the windows full height are striking, but as you cannot possibly achieve the same position being your external walls are different lengths, then I would create identity of their own, either by UN matching the style, or the layout. I like the full height from the interior, however, perhaps on the right, I would adjoin the window to the central panel, and extend it across with the glazing bars on the right, leaving the adjoining window a fixed, open pane of glass. Lave the same width of wall exposed on either side working from the outside in, that way the sight lines would be improved, and each room it's own unique vantage point.
For the ground floor, again, elongate them, shorten them, and lift as high as you can, it will improve sunlight exposure, and provide useful wall below them, form he inside built in joinery can really impact your interior. Bookcase, window seat etc.
I would also keep them as a single pane but with the top section divided and awning opening. So effectively, two rectangles, small one on top, larger pane below.
As for your feature area, would make it something that links into the window frames, architectural, so perhaps a nailstrip ethical cladding in a colourbond grey, or if budgets allow, a copper cladding panel. It will age beautifully, and I would uplight it rom your portico so it is really a beacon of welcoming.
Infact, I would continue it down below the portico, as if defining this central detail. The front door could be painted to match this element. I can even see a really stylish opportunity to use this portico roof, and clad the front columns in horizontal slats up most of he way, leaving he top boxed out to plant with cascading, heat tolerant plants.
Striking and architectural, use landscape to create vistas from inside, and up light to dramatic effect. Plants like mother in laws tongue, ground covers and cascading dichondra falls, all will soften the architecture which can remain unapologetically bold.

@Susan Ballard, yes in the 3D render my floor plans are a little skewed and the floors aren't aligned properly, but in the actual 2D plans the top panel and door line up correctly.

@mldesign, thankyou! I've mocked up what I understood from your feedback, not sure if I have understood it completely. I also love the uplight on the feature panel idea. I didn't quite understand your boxed out portico comment. I think you are saying to do a parapet roof?

Today we saw some houses that had horizontal timber panelling that extended the windows horizontally, and it looked terrific... I'll try to mock that up too which I think follows what you are saying about elongating the windows.

@Pazz, thanks I'll have a crack at an asymmetrical design. Because we're extremely space constrained we've ended up with a very flat façade, with only the entrance and feature panel providing any depth. So it's a bit harder to get something interesting & asymmetrical happening. Anyhow I'll have a crack at it and thanks for the example.

Geez I am not very good at design. I've had a go at the top floor windows, but I don't think I'm making much progress. Have also changed ground floor roof to parapets. I'll post up more attempts as I go...

Your doing great! I really like the look of the parapet for the ground floor, concealing that roof, so the first floor rises from that, looks interesting. I think it makes the windows here look better, and the timber detail joining the top window is nice, particularly if you use this detail elsewhere. I'd like to see you replicate only the glass part of the upstairs window on the other side, so the larger wall side has the extra timber detail, t the other window has the same glass measurement. I would then make the section which is the long rectangle, (small side of window) a louvre! On both sides. Allowing better ventilation, and looks great from the interior. Bo windows inside will appear the same, however the detailing outside is what gives them distinction. The ground floor windows could be enhanced by framing them with a protruding timber box around them, somewhat like a seat depth all around it. You could just do the one side perhaps the left to balance out the upstairs detail, and it will create an impressive effect under lighting. Downlighting built into it, and perhaps even the bottom like a giant planter box, imagine a large timber square framing the window, about 300mm deep out from the wall, then the bottom with a recess for interesting plants. Takes a 2d looking elevation into something of a new focus, instead of it always needing to be the entry.
Remove the parapet from the entry portico, it's much nicer pitched, that low pitch makes a bold statement to the entry, I would personally widen it further, so the eaves were around a meter, giving that elongation to the roofline that upstairs has, and using timber lining to the underside of it, to create a rich and inviting entry.
With the walls being parapet, this pitched portico would run seamlessly into that.
Hope this is helpful, rather than stressful!

Thank you so much for the feedback and encouragement. I think I understand your ideas though I am not so confident with the proportions... I was wondering if you'd be interested in doing a pencil sketch of your ideas for a fee? Could you send me a private message if interested? Thanks!
