I'm amazed that this discussion has carried forward for nearly two years! In that time I have moved to another coastal area (cooler climate and better proximity to children) and this time found most of the discussion still rings true. Finding another home here was an incredibly frustrating journey made all the worse by a mad investor rush in the area just when we arrived to start our home search. That search took the best part of six months and in the end there would only be three or four houses to choose from in any week. Result? A rushed purchase, a desperately inadequate building inspection and failure on my part to notice poor bathroom tiling, shortage of closet and storage pace, just how small the lounge room really was, and etc. I disappointed myself because I had let the pressures beat me and now we are trying to resolve all of these issues in a home designed and built by one of this states most respected project home builders 25 years ago. Having now studied the floor plan with more care I realise it was put together (designed) in modular fashion - most bedrooms have similar dimensions and the living areas are all approximately the same size as if the designer simply juggled three boxes of one size and four of another size and then worked out traffic flow. Then he must have thrown them all in the air to see how they would land and that was design number two! And etc and so on. This house aside, we looked at a great many during the six months because we had to broaden our search above and below budget trying to find something. There were massive termite problems, leaky roofs, asbestos galore, gazzumping at every turn, almost all but the most expensive properties suffered at least one substantial fail for the most basic of needs and to top it off the best home in our price range just happened to be built on flood prone land - approved by council who put the flood signs up less than five years earlier. We live and learn. Then there were the real estate agents, but that would take another two years and I doubt the internet has enough free page space available!!! OK, I hear you, they're not ALL bad...

I would inlay it into a frame..ie with a base to hold the marble..then that way you can screw/weld the legs to the base of the frame..

Lots of ideas here https://www.google.com.au/search?q=How+to+build+a+marble+table+from+an+offcut&ie=UTF-8&oe=UTF-8&hl=en&client=safari

Thank you everyone so very much for your responses and advice. I liked the idea of having a bold piece to tie the church in but like a few have mentioned, something simple might be nice to not overshadow the pieces we've collected. The Nick Cali nesting tables might work quite well, simple but still have the raw wood and we can move them around. I also like the idea of a round table. Annb1997 we actually looked at the carved coffee table, it's super cute and pretty it's a shame that it's just a bit too low to be functional with the sofas. We are probably looking at something around 45 cm in height...but we might still get it anyway and add it into the library nook. We move at the start of Dec, will post photos :) Here's one of the current owner's layout. Thank you again everyone you've been amazing!
