Why not telephone the Estate Agents selling the houses? They may be able to put you in touch with the designer who did the show homes. I did this with bedding I saw in a show apartment a few years ago and was successful in finding out where it was from.

I can't find the exact one but it does look similar to quite a few on grahamandgreen.co.uk Hope you find the one you're looking for!

I'm in love with the blue and cream cushion but I can't find it anywhere! The pic was taken from a house being sold in London, perhaps 6 months back. Surely such a fab cushion is still available in the market. Please help me :)

Hi Steph, you maybe better re-posting this in Design Dilemma or Photos it might get a little lost here. However, they maybe 4" diamond pattern tiles, they look like individual pieces and you make your own design/layout. :)
