If you are seeking a truly open feel to the floor plan you have shared, then using one material in the mail living area is the best approach to making this space feel truly open. Using a variety of materials on flooring chops up the space and decreases the visual footprint. I would suggest using wood, tile, or if you are on a tight budget laminated flooring for the living/dining/kitchen. Then use carpet in the more intimate spaces; bedrooms and possibly hallway. Save the tile for the bathrooms.

Sanded and polished timber floors have a evergreen classic appeal that never goes out of fashion. Carpet and other floor coverings do have a tendency to have a style that is relevant to a particular period in time. Have you ever walked into a home and thought the carpet, lino or tiles were from the 60s, 70s or 80s? Natural timber floors never date and you can easily update the look of your home with warming floor rugs and furnishings. Carpeted homes may pose problems for Asthmatics and those that suffer from allergies. There are a few environmentally friendly coatings available if you do choose to sand and polish your floors. This link will offer some insight into your floor coating options. http://budgetfloorsanding.com.au/timber-floor-finishes/ All the best with making your decision

Please help me to find a suitable rug for my carpeted lounge Carpet color : Brown/beige Walls : off white Couch : Ivory white with walnut brown arms (Planning to add lots of plants and a walnut brown coffee table as well)

Thank you for your comments. I really appreciate your help. I think we are on the same track. The rugs I have brought home have fought with the terracotta colour plus the busyness of the small tiles. I did come across this picture on Houzz, which I think looks good. What do you think? It would need some of that burnt orange from the chair upholstery as well as the aubergine to tie in but I liked the dark border line, it matched with the grout.
