That's a tricky one! There are obviously 2 arguments for this.. Based on (I think!) current trends, I would add a utility and make the dining room a family space so with enough room for the table, seating and a tv. I may be tempted to extend out the back by 4m if it doesn't compromise the garden and is in budget as it makes that space more workable as a family room ( appreciate it is very long though!). Can you also convert a part of the garage out of interest? On the flip side, 15 years is a long time and the house will likely need a new kitchen then and therefore purchasers may be able to reconfigure the space to suit them although utilities would be trickier. I came across this article as I wasn't sure if estate agents took into account the square footage of any storage when valuing houses, as I know ours didn't feature in the floor plan and we're lucky to have quite a lot http://www.countrylife.co.uk/property/guides-advice/phil-spencer-on-valuations-34312 From a surveyors perspective though I believe storage will impact the valuation but whether it equates to the same in price per sqf I doubt it??! It's a shame you don't get any surveyors on houzz really! I think in any case it would be an idea to recruit the services of someone like One Plan or maybe an architect ( karen at One Plan gets excellent reviews though!) to get a space that properly functions and will either appeal to a wider market or can easily be reconfigured to do so. That's my completely non-pro ramblings!

Rebecca thanks for the help! Kinorigo looks amazing. They have a black and white dining table that is just beautiful. Would be great if they also did that as a coffee table. They only offer a bespoke service? Sound a bit scary! Can you pm me a price estimate if you've had something similar previously? I'm currently torn between the Platner, the pedrera by gubi and the 'my moon' table my morose!! The gubi is probably my favourite just because of its classic simplicity but it might get a bit lost.

Great space. Not sure this is big enough but childproof & good price. White gloss. Two of my friends have this table. http://www.next.co.uk/homeware/dining-room/furniture/10. Dar Lighting do some great big shade pendants.

All of them are beautiful, and final choice would really depend on the interior style and look you would like to achieve. But to choose for now it will be Dark - Blackbone reclaimed oak table.
