Home rennovation layout and interior design

We are undergoing a major renovation to our 100-year-old Tudor home. We are in the final stages of design with our architects but we can't get the floorplan layout quite right. We are looking for help from someone with a fresh perspective to help maximize the floorplan layout for a couple of spaces. Also, going forward, we would like to continue the relationship for interior design help. This could include lighting, tile, paint, furniture, etc.
