You could go wider but it depends on what type of dining furniture would want to use and how many you will be catering for. Bench seating tucks underneath and when it is being used you aren't so worried about the other space. You could always turn it around the other way [ perpendicular to the house] so the width is less of an issue as 10 metres is a decent length deck. I think even an extra 30cm would make a difference and not doing it may cost more in regret than the materials. You could go wider in the dining area only but it is a bit hard to judge without seeing the space. Find some furniture you like online and map out a plan for yourself - use newspaper for life size modelling. Good luck

Hi anzella, loving the new table and chairs, because you live in North QLD I wouldn't worry about a rug under the table, apart from you climate I find rugs under tables can become very annoying . If however you do decide to have one down the track, Sisal Rugs are great for your climate, you can even make your own to whatever size by buying the sisal and edging it yourself or getting a carpet place to overlock the edges. Some years ago I made two very large rugs and edged them with a wide black tape, I stitched them by hand, loved them in the dining and joining living room.What a shame you can't have the hanging lamp in the picture over your table, not sure if it would fit between your ceiling fans. cheers https://www.dealsdirect.com.au/product.aspx?saleID=1774c795-993e-4615-afbc-f53a2e1dcab3&productID=ojiuDsjunkG1Vz9n7zBrLQ&sc=7&c=12&mkwid=siJYklREw_dc&pcrid=189771976719&pkw=&pmt=&product=ojiuDsjunkG1Vz9n7zBrLQ_6xX6Gc4vLkKMpQtba7S3jw&gclid=CjwKEAjwoLfHBRD_jLW93remyAQSJABIygGp4cKCQmlURqkE4IbUxZFOwwVQKSQHTM9Fx7Xllv1FvRoCWqrw_wcB
