I've just started that joyful feeling of revamping my old furniture. Nice pieces when we bought them not as great a look now but of course it's still quality too good to throw....the after pics are very satisfying

I'd have a look at the IKEA room layouts in their catalogue or online. You don't need to use their furniture to "borrow" their layout ideas.

All looks good except I would like to see the opening between the family and dining opened all the way wall to wall and either move the Fridge or Pantry to the other side of the kitchen. This will make the space look more open and feel bigger and allows for the dining table to be extended by just rotating cheers

A dining room rug should ideally have 24" or more of extra space, surrounding the table. The guests should be able to pull out the chairs easily without tripping over the rug. Choose flat weave or low pile rugs because spills are inevitable from the dining table. Maintenance and cleaning become simple with flat carpets. You can also choose carpet tiles as they can be set up according to the shape and size you need. Rugs come in many colors, patterns, and textures. Feel the texture if you are purchasing a natural fiber rug because natural fiber rugs are hard and rough as compared to cotton. Match the shape of the rug with that of the room. Match the rug shape to the room shape and the table shape.
