Your current plan is a lot wider than the front elevation you envision:

Mark gives good advice. The money you’ll save in the long run hiring an architect is what you need to consider when a designer seems like a more affordable alternative, if that’s what you’re considering. They can also give you a pretty good idea on costs and where you can make changes to save money.

In CA architects are way more expensive. However designers are licensed. Do as Mark suggested but find a designer who is creative and thinks like an architect.

I don’t care how much a cad program costs, you still need someone who thinks creatively. In fact the best architects and designers think best with a pencil and paper and not a fancy CAD program.

If you do move forward with this plan I’d add more windows to bedrooms 2 and 3. Seems to be lacking a good utility closet for a vacuum, brooms, etc. really the best test for a plan once all site considerations are addressed is laying out actual furniture in the plan. This test will show if windows / aisles / overall spaces are actually working and also helps plan for final electrical plan.

I live in Canada and I will say architects maybe are a bit more expensive here but if you go with a stock plan every tiny little change you make costs money and IMO an arcitect is still the way to go BTW anywhere in Canada with our snow loads are going to be an issue with all those gables most of which are completely useless.I never like going through the bathroom to the closet, never like a master next to a FR .Corner pantries are a huge waste of space , a laundry off the DR is not ideal. I agree go to the ARCHITECT with a list of wants and needs . A site inspection is the first step in designing a house and I will tell you no designer I know can do that properly. By the time you get this plan tweaked you could have designed an amazing home with an architect. Many things need to be tweaked in this plan and if you really have to go with a stock plan at least get one from Canada since we have many different codes than the US.

Yes, you really do want to hire an architect. Why? Probably a 'Designer" did the design on the inspiration photo you provided. How can I tell? The faux stone on the porch and entry and the base of the columns are probable, i.e. if it were real stone, it could be considered the structural support for the columns and porch. But the continued faux stone on the walls of the house and the garage shriek "semi-tract home McMansion!", because if you were using real stone as structural elements, you wouldn't have used it there. Plus the stone veneer does not extend around corners but ends just short of the edges of the walls revealing a thin white line on each end of the house. And roll up garage doors that are made to look like period correct carriage doors add to the aura of un-authenticity when looking at the over-all design. Finally, the dreadfully overused Joanna Gaines put a large sign of obvious functionality (i.e. "Eat" in a kitchen, or "Read" in a study, or "Play" in a child's room, or "Welcome" 4' high by the front door) definitely says "Designer", not architect did that home. Yep, get an architect.

In addition to the comments above, a few other things that aren’t great about the plan as is:

- that a private space (the master toilet) can be easily viewed from a communal space (mudroom) is not good

- you need more mock up furniture - then you’d see how much a dining table is going to ruin the flow of the house as the family arrives via the garage; also what wall would you put the mast bed? Is that how you’d lay out your living room furniture? And are matching patio doors on either side of the fireplace what you want or does it just look symmetrical?

- given the Canadian weather is going to include snowy shoes - is work hard to make a mudroom that is separate from the laundry room - why have your clean clothes in the same space as your dirty shoes

In Canada, you may also consult an architectural technologist. Bear in mind, this pro. classification is not available in USA. https://en.wikipedia.org/wiki/Architectural_technologist
