Definitely would NOT put grills in one window and not the others. Its is more acceptable to NOT put grills in a center section while the flankers have grills, but if you are going gridless everywhere else, I don't see how that would look right with a big window with grids in it and nowhere else.

IMO this house does not suit window grilles and please remove those shutters too. IMO that space for the window looks off to me I think the new window shuld be at the same height as the window beside it is there a reason this window is so high and near the ceiling.

I have no ideal regarding "why" the window placement is thus. The living room windows are the same height as the bedroom windows (far right). The bricked section where the other window is was actually a carport turned into a den. It was a later addition. I do agree that the shutters need to come down.

Thanks for your opinion about the grilles, I wasn't sure about mixing window styles. I would really like to replace that window in the den (bricked section) but it would be rather costly tearing into the brick, etc.

What kind of window would you use? Currently there are two 63h x 40w windows with no space between them. It's like they are joined together without any wood between them. Rose

We are in the middle of picking out new windows for our house now and I'm going for a specific look to our house and have decided to put grills (a thicker valence/short fractional grille) on most off our windows but NOT on our large living room windows which face our mountain view. I like the curb appeal of a grid but I didn't want to impede our view. It's done that way a lot around our area. I've found that picking out windows, choosing which windows, with or without grilles is overwhelming but I've finally made some decisions!!
