turret has a 11 foot diameter

Hard to tell without a floor plan. How about a round games table? Or a round couch. I have one but it’s been discontinued. Others online.

@emilyam819 yeah was thinking of building a custom seating bench along the window and a round table in the center. Would be fun to play games there but the idea of a built-in couch/table as well as a sectional/coffee table seem like it could be too much for the space. Don't want it to feel cluttered

Don't know your style (nor colour scheme) but 2 armchairs with a round table is something that can work in that area. Cannot say where you can place your sofa without a floor plan showing all dimensions and more information.

@lisedv Thank you! I think that may the the easiest solution to get up and running. Here are some manual scans I did with my phone to create a floor plan but the turret did not show up correctly because of the curve. The diameter is 11 feet after measuring with a tape.

There is also a dining room connected to the living room with a smaller bay window whose dimensions should be correct. I have plans so far. Just jumped on this place last minute and so everything is fluid. Wanting to lean towards green/burnt organge warm colors for the living room. Maybe replacing the current pendent light with a linen or wood pendant light and some additional lamp lighting
