I found these interesting lanterns at Shades of Light. I had seen a lot of nautical, Arts & Crafts, and modern styles of exterior lights, but I was looking for something that would have a hint of Western farmhouse style. The Catskills were actually a part of the United States' first frontier and "Wild West." These bronze outdoor hurricane lanterns are no longer available, but I highly recommend Shades of Light as a source for something unexpected. They've got lots of styles in their catalog and online.
I used a pair of the sconces at the front door and a single one by the back door. They came in two sizes, and I was very careful to find a size that worked with the scale of the house. I haven't done a lot of specifying product like this, so I didn't place my order until the house was under construction. I used poster paper and roughly sketched the sconces in both of the sizes that they came in. I highly recommend doing this. The drawings don't need to be perfect. After creating the silhouettes, cutting them out and taping them in place on the side of the unfinished house, it was easy to decide on the right size. It was also priceless in determining where to actually have them mounted on the house, which is a decision you definitely want to make with your builder.
I should also point out here that there was one thing that I found really disappointing with my decision to use vinyl siding on the exterior of the house. The product requires mounting boxes, which came in a standard size that is larger than the mounts of my light fixtures. It's a dead give-away that the siding is vinyl, but I like to believe (or hope) that the strong character of the light fixtures distracts from the mounts in the wall.
