I am trying to decide where to place the windows in my house plan since my architect needs an idea. I'd planned on buying the windows from Lowes since we don't have much around here to shop from. I was thinking of just buying the single hung double pane windows and spacing them out. Some areas in the house would probably look better with the side by side windows (don't know the term for them) but I don't know how much more that would cost. For example I want two windows on one wall in our master bedroom but they would look better placed next to each other than 7 feet apart. How much more would it cost to have them made to be placed together or can both separate windows be placed close enough to one another without having to buy something special made? Is there a term for side by side windows? I'm not really finding much when typing that into the search engine as far as sites to buy windows from.
