We bought a 1930s house have opened up most of main floor incl small kitchen, diningroom and living room. Now its an odd shape to decorate. Contractors start this wk to complete painting, floors, trim and lighting. The dining room is much bigger than living room. I would like to add a fireplace/mantel/tv wall/area but not sure where or how to decorate to utilize space. Here are pics. Sorry i dont have measurements

kitchen opened up into dining room.small breakfast nook/island to go onthat half wall large dining room area that opens into a smaller living roomthis was two rooms opened up into oneon right side of that window is the front porch doornew stairs built with under stair storage behind that door. Small powder room in right corner. Also little areabehind the couch on right wall
i do have option to close up this window the outside of the window is a closed in front porch. This is small living room area
