Not sure how the kitchen is laid out, but it seems rather large in comparison with the main living area.

I think this piece is quite lovely. It appears that your couch and chairs have dark wood so I would be tempted to stain or paint the buffet to match these items. Changing the large modern handles to smaller antique ones might help to make it less bulky looking and tie in with the other items in your room.. I like the idea of putting a mirror in the upper door, however much as I like the criss cross effect in the sample pictures, adding more detail may conflict with the curves in your sofa and chairs. You could look for a decorative detail that has more subtle style. As for placement, it might go on the short wall where you have a bench or even on the wall where you have your table with two chairs, one on each side to balance the look.

Hello Sherbaaz, I hope you are doing well. Here are a few cupboard layouts that you can use. You can also add glass doors or opaque doors to these layouts as you wish - For a more decorative option, you can do it as follows and also make space for a pretty painting or a mirror. Hope this helps!
