I would not do 3 windows in the gable just 2 like on the house and simple garage doors no criss cross trim

Thank You, agree on the doors, no criss cross keep it simple- what about the Garage door windows? That’s stumping me. The garage windows above and on side are 2/2 SDL Marvin

I am seeing gables on othe sides maybe too many gables but IMO all gables with no triple windows to keep the garage looking really like the house as much as possible Maybe something like this it could even be matching the front door in finish just not some many panes so like the house windows layed sideways

It’s a shed dormer off right, and the man door in right back has a small portico. The triple window is ordered. If I were to change that now I’d end up in divorce court

Ideas to consider.

There is a big difference in the way that windows on garage doors are designed and their appearance. You get bigger, normal looking windows with some of the more expensive lines/collections in the better brands.

Personally, I find that most garage doors with windows just make the house look more busy.

If you have regular windows in the garage space, then you don't need windows in the garage doors.

That’s what it will look like except a triple window above white garage doors. We have onion lights on house and on front lamppost. I like the triple window look 🤷🏻‍♀️

Here’s another idea

There is absolutely nothing about the proposed garage (or commenters examples) that is even a watered down assemblage of Greek Revival elements, it is presented as a watered down Craftsman style (as are the commenters examples).

The house has 3: the gable end eave returns, the entry door trim, and vertical proportions. The corner trim and frieze board are nods to the style.

So the overhead garage door style is moot if that will be the only element, but really there were no garage doors in that era to set a precedent. So if the Greek Revival style is carried to the garage, at that point flat panels would be appropriate to not detract from the surrounding elements. An example of a "flat" overhead door that doesn't detract from the style elements:

There were barn or stable doors during the 19th century in America! (Though they definitely did not have glass set in to them...)

Some fancier antique barns have long, one pane high, horizontal windows above the sliding barn doors to let light in to the center section.

Garage door installer here — lovely project. For an 1850 Greek Revival I'd keep the doors simple and let the architecture do the talking. A few thoughts:

1) Style: the crossbuck (X-brace) doors on the plans read more barn/farmhouse. Period-correct for Greek Revival is plainer — a carriage-style door with vertical board detailing or clean recessed square panels, and no X. If you love the crossbuck, keep it, but simpler will sit better with the house.

2) Windows: if you put glass in the doors, copy the 2-over-2 lite pattern from your gable windows — consistent lite patterns are what make a new build look "right". My own preference on a white Greek Revival would be solid doors, with the triple gable window as the feature.

3) Material: get the look without the upkeep using insulated steel carriage doors with composite overlays. Real wood looks great but is heavy, needs refinishing, and costs far more. Ask for an R-value of at least 12–18 if the garage will be heated or you're in a cold climate, plus full perimeter weather seals.

4) Practical bits: two single doors (as drawn) are more period-appropriate than one wide door, and if an opener ever fails you're not stuck. Make sure the header and framing are sized for the door weight, and check headroom above the openings for the tracks/openers before the framing is finalised.

Colour-wise, matching the alabaster white is the safe, classic choice. Good luck with the build!
