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!

It’s available at Dunelm UK, Joss and Main, Temple and Webster have a parquetry coffee table as do Interior secrets, coco republic, if all else fails a craftsman could make the nesting set for you.

Ok if putting coffee table I would put rug under table if it is sitting on the carpet not in lounge area

Have a look at this gorgeous coffee table from trit house
