I don't understand the wood screen. I'm not sure it's going to be high-performance.

I'd stick to a very simple siding, probably just cream stucco. The wood screen thing is the feature of your facade.

The AI seemed to show gray roofing on one side of the second floor. That looks awful, IMO. Again, I'd stick to one siding. I'd enhance the house with landscaping.

I'd lean into the 1970's of it all. That should at least bring some coherence. Right now it is typical 21st century too much of a muchness. Try to get it down to a mere two cladding materials.

I see no benefit to the wood screen and really adds nothing worth the price . My question always is are you truly going to use a deck that faces the street and your entry ?

I appreciate the inputs. The wood screen functions as privacy for the deck behind it and it's part of the 2nd floor loft that has a view . The intent is to use the standing seam as the cladding for the 2nd floor, I guess modern barn style. I agree with only 2 cladding materials that makes sense, and then some wood accent such as the wood screen is our intent. The image below is achievable (plus more landscaping)...any thoughts on how that would translate for my design above?

Subtle, modern and crisp with standing seam and a thermowood screen already tells you the answer: keep it to two main materials plus the wood. Something like a darker panel (fiber cement or SwissPearl type) on the main mass, smooth light stucco on the secondary volume, and the thermowood as the only warm element. Pull window frames, roof and fence into one dark tone so it all reads as one decision. On a corner lot that people actually walk past, wrap the main material around the corner instead of stopping it at the front face. The side elevation gets seen just as much.

I agree that the Blvd. side is just as important, I would want that side to look as grand as the front.

I don't like a two tone look. IF stucco is the choice then go dark rather than light.

I do like the wood screen, adds warmth and interest.

Ok, very good, thanks! A couple of additional details please: can the privacy wall at the front main floor deck be the same wood accent or should the wall material cover and wrap it. Likewise, there is a recess on the boulevard side...does it make sense to fill that with accent wood? For the fencing, ok to use the same tone as the accent wood, or still prefer to match with the dark window frames and roof?

@Topla Hisa Wrap the privacy wall in the main material. If it goes wood too, the wood stops being an accent and the front gets busy. The boulevard recess is the perfect spot for the wood though. Recesses read as carved out, and warm wood in there gives that side real depth. Fence goes dark to match the windows and roof. A wood fence competes with the accent and drags it out to the street edge. Keep the wood to one or two intentional moments and the whole house looks custom.

Thanks everyone for the solid advice and gives me a kick in the pants to think about this more objectively...

Assume an existing house in the last pic with the foamcore model.

You've given your house a new hat. That hat could be removed and put on any house. There is no relationship to the main floor. I also count 6 or 9 different materials in the AI pic, too many.

You've all emphasized to minimize the pallet, here's the next iteration. There will be a 2ft concrete retaining wall + wooden fence with horizontal boards on the long side along a city sidewalk, which will be lined with shrubs and coniferous trees to conceal the front from the corner. The approach below will enable the back deck and a garage cabana to relate well to the house. Any comments pretty please and thank you very much?!

Thanks for all your advice, and now I can see the secondary warts that I need to work on but I feel the base is at a good starting point. Alongside those points you highlighted, I'm noticing things like the thermowood screen board spacing and size all make a notable difference on the big picture...lots still do.
