We've usually seen it referred to it as "subdivision Colonial" - but there's bound to be someone out there who can put a finer architectural style point on it.

Don't think your house has a standard, 'period' name and does it really make a difference in the landscaping approach?

At first glance the house pictured reminded me of a thread on this Landscape Forum some years ago titled "Welcome To My Garage". It was a very interesting discussion. Educational, too. On a chance I searched "how to landscape a welcome to my garage house style". Some very helpful ideas appeared including snatches of our original Forum conversations. You should find some directional thoughts to mull over using this search suggestion.

the porch mitigates the degree to which the garage is forward of the body of the structure, but homes where the garage is thrust forward are known as "snout houses."

Yes, they're everywhere. And I still bet the development sellers billed this as a "Colonial". It would have a model name like "The Jamestown", "The Valley Forge", etc. etc.

Throw on a mansard roof, and your ersatz French selection would be "The San Souci", "Vue Claire", "Mon Reve".

Not sure this was exactly what the OP was looking for. :-)
