If you don't need the drapery panel to close all the way, you could use 2 short rods, one on either side, and hang the panels that way. Or, if you need the drapery to close all the way, you would need a an H-rail rod, pictured below.Hang the rod at the crown, with 2 "center" supports, one on either side of the arched window and the ends. The type of bracket shown allows the drapery panels to move freely with no obstructions.

#3. All brick with siding under porch. Get rid of faux stone accents on corners at foundation. Do not pay extra for those. They are awful. If you have to have stone, only do it along the base of the foundation. Paint the garage doors as close to the color of the brick that you select to remove emphasis of huge garage doors. There is no hiding them, but you don't want them to be the focal point. Why #3? It has the most simple elevation and avoids most of the McMansion from Hell elements. That's why. If it were me, I'd do all brick. Then, I'd paint the brick and garage door the same color.

I would put a simple window film on the arched window. It will give you enough privacy, light coming through, and cover the bad view. You can use a slightly frosted one, or maybe one that looks like seeded glass to match the style of your home. There are los of options. For the square window, you can use a woven wood shade or other blind. For interior mount, you need to measure using the larger outside frame and look for one that will work with the narrow dimension for installation. I think it would be best to mount a roman shade over the window at the ceiling. Then you get the most light while the shade is up and don't have to drill into the beautiful wood frame. You could also mount a rod above the window and use a simple linen drape on each side to pull closed when you want privacy.

oh man,,,no shades for that door. it's a beautiful door. (are you doing a UV clear coat to protect it? It doesn't look like anything was applied to the exterior. please look in to Penofin oil, the Marine one. that mahogany is gorgeous but you have to protect it or it will turn a horrid gray shade over time this is Ipe, but your mahogany will react similar. It will deepen and look even better after applying this oil it will protect it from any sun/or water and UV rays. it's easy to use and only needs a touch up every few years. if you don't do anything else to that door, do this product! if you MUST have privacy, then call in a glass guy and have them install some type of glass to the panels. A rain glass would look great. or, maybe they can apply a reflective film that is not noticeable from the inside
