Here are the rest of the photos:
(1) Architect’s drawing of exterior of house
(3) Inspiration photos

Not sure how to edit my post, but I thought I should add we will also have a wood burning fireplace to the right side as you will see in the architect’s drawing.
Here is a photo of a bathroom my husband and I both really love that is not like the crisp, clean modern look we also love.

NONO NO arched windows . French famhouses are old and almost always stone you do not have one .IMO you have added a monster addition that is no way suits the house at all.IMO you had a nice farmhouse with even before had too many gables and odd roof lines and now you have added more of the same . It is too late now to change much so siding, that nice stone chimney and as for the interior the bathroom you show can be anything you want but IMO not with the house you are building. Waht I think of when I see the new house is a mountain home not french country and not farmhouse .

Your request is major. Consider finding a local competent architect to consult on the design. The picture of the existing house has more charm than the 'architect's' drawing.

If the person that designed the addition claims to be an architect, verify their license with your state.

Ours is a different style, but similar in that we have dark siding in a pattern (Hardie Iron Gray) with matching Iron Gray trim, a black roof and black casement windows. We leaned into the landscaping - including a curved walkway - to help soften the outside.

Here's a mid-construction shot but you gives you an idea...

It's already not "of a piece" to the original house, by being significantly taller with a huge gable front and center. I'm afraid that you are in the "contour the nose" stage, rather than "do some plastic surgery to the plans" stage.

You will need to make significant changes to correct the course. Hire a different architect than the one who created those plans.

Not a pro, but if it were my house I'd want to invest in some good landscaping and probably consult with a landscape architect or other pro. The right side / fireplace wall rather dominates the facade, so I'd want a nice tree there. A welcoming walkway would warm it up too. I'd want my front door to be the focus so you might consider a color there or a pretty wood finish - BPMBA's is a great example.

" My question is how can we soften the exterior house with all these clean, straight lines-if possible?

Lose most of the black. Black windows do not go with your home style in my opinion but they are ordered so do not compound that with black siding and black shingles. You will end up with 3 blacks that do not match.

" And will it be silly to have any arched doorways in the house? "

Absolutely.

Maybe you want to break up all that board and batten siding with other materials or a bellyband.

The picture of the existing house shows a single window in the second floor gable; the drawing shows three windows. What is the room behind those windows?

There was a lack of communication/ editing- regarding "soft versus hard) as I said in the other post, along with other replies saying same.

Can you show the two dimension interior floor plan with ALL old and new and dimensions? Not renderings and elevations. the feet and inches ........on paper.

Downplay the new Left/Right dichotomy by emphasizing the horizontal elements--divide the structure into an Upper/Lower design of the two stories by painting the first floor gray (or a color) and the upper floor in white. --A take on Bev's last inspo photo. My sketch:

French Blue

It is bad practice to design a home based upon one elevation. All elevations, floor plans, and the environment in which the home will set is required. The help this design needs will not be found from a committee on the internet. You are spinning your wheels in search of free advice.

He already have two roofs over two doors so you don't need an arch and it won't look right with the style of the house you might be able to make an arch inside the house into an adjoining room

Is is too late to start over completely? At the very least, ditch any an all funeral hearse look.

I have an idea for the front of the gable. Make it resemble a barn. Keep with the white and add some windows and doors...

Since he windows have been ordered it's too late to make style changes. You can't add much French country vibe with no mullions in the casement windows.

I'm curious why the heads of the windows in the existing gable got lowered and why the large masonry chimney doesn't extend above the roof and why it would be so large for a wood stove.

Since the wedgie space between the old front facing gable and the new long high roof looks awkward and is possibly a water and/or ice problem, perhaps it could become a shed dormer.

Vertical siding should not meet the roof eave; put a continuous horizontal frieze board there and one under the rake too. A greater level of level of trim detail should be shown on the amateurish elevation drawings.

Landscaping is the solution. I wonder if you can find French Country bushes in your area. Probably the bigger the better.
