Do you have a photograph of the front of your home? Without that or some further information about your home's exterior, it is difficult to make a recommendation. In the mean time, we have a few idea galleries you may be interested in browsing:

Good luck!

This is the outside

We suggest a classic panel door in a bright color, like the attached photos. The color will liven your entry and help draw the eye from the curb. With the large picture window in close proximity, you can opt for a solid door, or one with smaller windows and still enjoy plenty of natural light in the space. In addition, you can brighten the door with updated accessories like larger house numbers, a door knocker and new handleset.
