How high off the ground is the porch floor? Most cities/urban counties have building codes requiring porches more than 18" or so high to have railings. The height is different in different places. You may have to replace the railing. If not, wood filler for the holes, sander for the rough spots, primer and paint.

Virgil - It's not required by code. But our elevations have one drawn so the city won't bless off our house without one. So our options are: 1) Put in a permanent railing....wood, nice, traditional. City loves us and we move on. Will spend $$ on a nice railing. 2) Put in a temporary cheap railing. City loves us and when they leave, we take it down. Will spend some $ on a cheap railing which will ultimately be wasted when we take it down. 3) Resubmit the drawings without a railing. More $$ for basically pulling another permit. Plus dealing with the city again. But then we don't have to put up anything and can focus on another project. At this time, I don't know the cost differential between nice railing, cheap railing and the additional permit cost. So from a cost perspective, I can't factor that into my decision at the moment.

I personally like the front door to "pop" (there's that word again LOL) and the garage door(s) to blend in/disappear rather than draw attention to them. In your case the siding is more prominent to the brick section so you may want to look at matching the garage doors to the siding colour - can the person who did the rendering show you what that would look like? As for the front door, if you love a red front door, go for it as it will put a smile on your face every time you pull into your driveway. I'd lean more towards the colour in your brick than a "Christmas" red if that makes sense. I can also see some nice Adirondack or rockers on your porch in the same colour as the door.

If a railing is not required, do not install it and live without it for at least a year. If you find a compelling need for one, install it at that point. Take the money you save and throw a better house warming party.
