I doubt you're going to find that EXACT bench ... the website says they are custom made to order in Australia. For something 'similar', I would google image search 'tufted modern ottoman chrome"

A few things to consider indeed, but what a great space to work with... my humble opinion on some of your points and queries... 3) if you haven't already got the cabinet/shelves unit yet see if you can get one with sliding cabinet doors 4) great idea, so avoid any heavy items of furniture (e.g. big armchair) in the centre of the room that will be harder to move/relocate and think more ottomans, bean bags, etc You are absolutely spot on with placing the wall units on the 4m wall and keeping the slightly wider 4.2m wall for seating facing the outdoors a) clearance depends on how much and what kind of traffic going through, e.g. doorways approx 700-800, passage 1000-1200, but to get around a coffee table to access couch or get around behind a chair at least 500-600 and more if you can accommodate... and of course depends on the type of furniture, e.g. if you have cabinet doors that swing open (as opposed to sliding) then you have to allow enough clearance to open the door and access the cabinet comfortably b) I think you can do better than a 2-seater in such a big space... e.g. let's say wall units base cabinets are 600 deep even with swing open doors of 400 you'll need clearance of say 1000-1200 from that wall on the right, which out of the 4.2m wall at the bottom leaves you with 3m... so I would fill up the bottom left corner by having a 3-seater/chaise modular along the remaining 3m with the 'return' chaise on the left along the 1.7m wall c) yes, you'll definitely need one large 'area' rug to define the space... you could even use two different rugs and create two zones... one large rectangular one framed by the couch and wall units and a second smaller round or asymmetrical one closer to the sliding doors paired up with a bean bag or big floor cushions d) I think a tall indoor palm/fern in a nice large pot just in the corner of the units and wall (to your left as you enter the space) would be a welcoming touch and tie in with the outdoors Good luck ;)

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!

Thanks Kate This is what room looks like now, posting a pic of what we were planning to have in the WIR ( table in WIR is like a make up table with Hollywood mirror ) My daughter seems to be more keen in having a large WIR rather than the study nook . So I’ll think I’ll leave as its (with large WIR) and at a study desk somewhere in the room. Think there’s room for that . Thank u ☺️
