To get a home that blends in, you would need to do more than just "flatten" the front. I don't know if I've ever even driven through Fairfield County but I did live in Maine for several years and one thing I remember about all the houses in New England was that they tended to be more "vertical" than horizontal. I just took a quick look at what's for sale in your area to verify that what I remember still holds true. And, sure enough, I saw only a very few single story homes for sale with more than about 1700 sq ft of living area. And once you hit around 2200 sq ft heated/cooled plus add a two-car attached garage, EVERYTHING in your area seems to have two (or more) floors. The result is that, regardless of the style (Federal, Cape Cod, Colonial, Saltbox) they all tend to be as tall or taller than they are wide. Houses that are wider than they are tall tend to be associated more with western states where wide open vistas and room to sprawl gave birth to "ranch style" and "prairie style" homes. In fact, that long, low "hugging the ground" look is pretty much descriptive of both styles. Thus, here in Texas, if you check the MLS listings, you'll find lots and lots of single story homes... even in the 3000 to 4000 sq foot range. In fact, if I were looking for a single phrase to describe the difference between the styles of homes that one finds in New England and those that one finds most often out here in the west, I'd probably say something like "in New England, the houses sit up straight and tall, while here in the west they lay down and sprawl." In New England, even farmhouses that have been added onto over time so that we speak them as "sprawling" still have a central two-story or 1.5 story core that give them an upright feeling. Whenever wings were added to the sides they were usually set back from the front facade and given a lower roofline so that the tall central core still stands out as the "main house." I THINK you might be able to design a house with a somewhat similar floorplan to the one you like that would blend into your New England neighborhood but to do so, I would suggest that you start by squaring up the central core of home (the kitchen, great room, dining room, TV room, and foyer). Then make that section 2 stories high or at least 1.5 stories with dormer windows upstairs. If you don't want any bedrooms upstairs, use the upper space for a bonus room. Or, if you really don't need/want a second floor at all, make the core room ceilings nice and tall (10 or 12 feet or more) and then have false dormers in the attic above to give the impression of having a second floor. Do keep the 8/10 sloped roof because you need the height. Then, push the bedroom wing and the garage wing back and give both areas a lower ceiling height... Maybe 8 to 9 feet depending on how tall you made the ceilings in the core area. That way, the roof lines over these sections will tuck in under the roof of the central core. That will tend to make the wings look like they were added to the house later. Because you won't have enough room to the side for all the bedrooms you want, you'll need to extend the wings to the back. (You don't want to keep going out to the sides because you don't want the house to get too wide.) However the wing extensions will give you a perfect patio area out the back. Then, if you like more of a "farmhouse" look, add a porch across the front of the core area. At 3200 sq feet (not counting garage or bonus room) the sketch below is probably bigger than you were planning to build, but maybe something along these lines would work for you. Do consider hiring a good local architect tho...especially if you want to wind up with a good useable design so you can start actually building anytime in the next few years. I'm not saying you CAN'T eventually design your own home. It isn't rocket science... but if you're a novice as you say, even if you're a pretty quick study, have a flair for design and are willing to spend a LOT of your free time on it, it could still take you YEARS to learn all you need to know. A good architect who listens to what you tell him and then tries to fulfill your dreams rather than simply impose his "artistic vision" on you can be well worth his fees.

I don't mind the garage color as is. It matches different colors in your stone. I do like BeverlyFLADeziner sample. I'm trying to mimic it but i'm having a hard time. Here's a try- Here is the same color but with matching garage I don't mind the original garage color. I have the same color brink on my home and our siding is a very light tan color.

Yes, since the material was not properly flashed and installed during initial construction, attempting a solid, watertight and insect proof wall at this point is probably too expensive to consider. I do think, as suggested, that a properly designed landscape screen using lattice (and perhaps with climbing, flowering plant material) might replicated the initial design and add some softening to the masonry facade.

I feel like a house on a lake is opportunity to create something special. There is nothing special about the house you posted other than a few superficial details applied to a tract home. I hope I am not sounding harsh, I am only encouraging a better home for your own good and enjoyment. Build something that will enhance your family for the rest of their lives, not just support it while you live there. The cost may be slightly more but the returns can be limitless.
