Where is this house being built? That does make a difference too.

Those window will need enough overhang to block the sun if they aren't facing north. For that the second roofline would allow for shading of the right window. You should check how the rear slope of the garage intersects with the main roof. Drainage has to be established.

I think the bases of the columns should be wider. I like Hardie plank. Will the interior be Craftsman style?

shakes on the gables look nasty after a few years.

Hardie board would be my choice.

3 matching size windows if possible.

Shakes on the gables will be okay if they are HardiePanel

One other thing. Being in FL, I would definitely make your eaves wider. You can easily go up to 24" wide without a problem. This will help with cooling.

Could you post the plan? I don't care about the layout, it just helps to understand the shape of the house and why the windows are located/sized as they are.

Here are a couple showing all gable, all hip and a mix, all with a smaller entrance porch. These have a lower slope roof with wider eaves.

Would look good in board and batten too.

Beautiful place for a home.

Like the bigger, more sturdy columns. What is that single window to the right of the entry? Have you considered adding a double window or a more decorative window, such as small bay window, there?

Would not use shakes for gables -- use a vertical version of your choice of exterior siding instead.

Agree with w/the suggestion of someone else: With the stone (or stone siding) at the base of your pillars, your entire single story home and garage would look really good w/board-'n'-batt vertical siding, especially if you continue that stone over any otherwise exposed block foundation and use it to face the vertical sides of the porch, too.

[You do have at least one concrete block for the foundation to face w/stone showing? -- at least one step up from ground level to any porch? Would improve the look and, importantly, enable you to have foundation vents -- unless you're going to have a concrete floor?]

Don't build a distinctly separate roof or building for the garage -- wrap that front porch around the left side of your home to meet that garage wall instead -- create a larger sitting porch there, screened or open.

Prefer the two, but only two, forward facing gable option (First pic of PPF a couple of minutes ago) with a 4'/12' standard rectangle roof for the entire house and garage and porches and also have a gable on each end rather than any hip roof

Do create a porch on both sides of the garage rather than having it jut out from your home. This would keep your roof a rectangle when viewed from above -- less expensive than a lot of angles and hips and unnecessary gables -- four gables and two ridges off the main ridge are enough.

By creating porches, including a larger one as your front porch wraps around that left front side of the house, all beneath a rectangle shaped roof, you have the option to screen in the larger porch and enjoy the summer w/less skeeters and other bugs bugging you. With both front and back porches and/or side porches, you and your spouse can enjoy a more quiet evening while any children in the family are making noise on the other side of the house. Creating easy access to multiple sides of the house will make for a great indoor/outdoor multi-generational entertaining venue.

Do minimize exterior wall angles -- unless an angle is needed to enable you to add a window to add your porch or to add an adjoining room. By adding several feet to a room instead, if necessary to straighten the exterior walls of your home, you could give yourself some more storage on the interior wall of that room or an adjoining room.

A hip roof or a barely sloped roof can be a hotter one; whereas in a standard 4'/12' or steeper roof, you can add vents in the very point of the gable as well as via the soffit -- less likely to have moisture/humidity problems that way.

Good luck on your project. Keep us posted.

Well...with a plan such as yours I would have expected the designer to come up with something much more substantial for the exterior architecture.

The exterior of your house is simply no match for the budget which you will need.

I suggest going back to your designer and having a good discussion.

Good luck on your project.
