House layout help

Hello,

I am planning to build a house (concrete) with a maximum size of 190 square meters, and I need your help. This is a preliminary layout of the rooms, based on the site plan.

What do you think ? Dining room and living room together? where else could I place dining room and guest wc (so it has a window) ?
