The railing around our front door needs to be replaced - it's starting to rot. We are considering instead of keeping the railing, adding a portico like this:

The front of the house faces due west, which mean this time of year, the afternoon/early evening sun is beating against our front door. Literally, the door handle will be almost too hot to touch by late in the afternoon! I like the idea of a portico to protect the front door (once during a very heavy driving rain this spring, we did get a little water under the front door), but also for shelter (guest won't have to stand out in the weather, and neither would packages, etc.).

I feel like a portico like the one attached would be in keeping with the style of the house. We have an arched transom/fanlight above the door, so I feel like the arch would be in keeping with the arched themes.

Before we potentially screw up the facade of our house, any professionals out there disagree with adding a portico, or with the style I have selected?
