Do you have photos of this long column ?

What flooring are you considereing? pattern on the floor can be used to disguise your issue. some patterns will highlight that same concern

Hi Pawan, Depending on your room, there are different methods to hide column edges. Column edges don't always need to hide, we can highlight it and make it an awesome edge instead of the awkward edge. If the column edges are in the living room or in a bedroom, you can use the open gap between two edges to make shelves. If it's in a balcony, you can paint it in different colors, paint it Aztec, make it an artistic feature of your home. Happy to help. -Thanks, -Neelam -Lines and Profile

Hi you can add a small section or a sheer partion screen and make a mud area for jackets umbrella shoes etc when people enter the house and so that they dont enter your living room directly. it will give you a better, more square shape for your living room. then it would become easier to design with wallpaper and textures. i suggest bringing in some air plants to hang by the windows. you can bring in some peppy paintings as well
