Hoping photo shows this time

Hopefully design experts can chime in, but I am facing a similar decision. We have gridless (in a center hall colonial) and never gave it a second thought. Walked the neighborhood and realized that more houses have grids than not - assortment of 6 grid, 12 grid, 6 top only. Coming back to my house I realized the gridless really looks plain, basic, and boring. The grids add a lot of charm. So my first suggestion is to walk your neighborhood and see what options are out there.

If you post a full picture of the house someone may be able to photoshop the options for you.

ETA: We have one house in the neighborhood with prairie grid and it just seems "off".

I think we need to know what the reason is for new windows and the style of house you like. I do not like grids but I also love MCM not colonial or traditional Window trim has no effect on the amount of light you get inside. IMO the dark widows would be anice change and if dark no grids or get windows that have removeable grids . As for the arched window the same as the rest what ever you decide. BTW I never care what the neighbors are doing to their house .

I think this house would look good with no muntins, or grids.

Thank you everyone who commented. I have been doing a lot of looking at other homes to try to picture what mine will look like ... I think I am really leaning towards no grids at all but i can't imagine what the large arched window will look like when left so plain. I wondered about a subtle Prairie grid but with all others plain but I also think it is probably a mistake to mix up the styles on the same side of the house. This is an overwhelming decision

My personal preference/focus would be weather rated double pane glass -- with or without grids. Some windows have removable grids but ... not really a fan.

Since you like windows without the grid but are concerned about the large center upstairs window with the arch looking plain -- deliberately make that window different than the rest.

... You might create a stained glass setting sun in the arch above a rectangle with no grid or hang an arched stained glass piece behind the clear glass.

... You could leave the larger / lower rectangle part of the window clear (without a grid) but hang a large decorative stained glass piece that reflects your own personal interests (beach, mountains, sports, gardening, etc.,) inside the rectangle window below that has no grids.

Just a thought. For sliding glass patio doors, at least, "grids" in between the double panes of glass mean you've then got the look of traditional grids but with the ease of cleaning of more modern windows. There are aluminum windows with the same kinds of grids.

The simulation is so helpful!! Thank you. It looks Plain but I kind of was expecting it woukd and I likened it to getting your hair cut off all at once.

Does anyone have any thoughts on doing grids on the top panels of each window only? I like the look of the grids from the curb but from inside my house it blocks my view of the lake - for Which I would only need gridless on the bottom frame. Also what about a very thin window grid which would be less obtrusive? Thank you everyone for taking the time to respond to these

My personal feeling is that too-thin grids particularly on the standard 6 light sash just end up looking cheap. The grids on top over single lite on bottom is sort of an early 20th c. look associated with modest houses, and I have never thought they were quite right for these bigger contemporary houses.

Thank you
