So many questions from my point of view. The furniture all looks a bit squashed. Is it correct that you want a circular kitchen island bench, or do you mean to place stools around an overhanging bench in the kitchen? The raised section near the dining table would have to be removed, or are you planning a new Kitchen? What is happening down the other end beyond the small mat? is this an entrance from a deck or back garden, or does the room venture further? If you are to change your sofas, make sure they are sympathetic with the new chairs and as the chairs look a plain creamy colour, should go with most fabrics or leathers. Due to the room not being over spacious, be careful not to select furniture on the larger scale. Have a look at Jardan furniture and Globe West, both these organisations have great furniture at not too exorbitant dollars. Arthur G steps up the ladder, made in Melbourne. I would prefer you started with the dining furniture, as this is quite cottagy moving forward with your new armchairs. The dresser too - although you could paint this an interesting colour so as not to apologise for it's heritage, again with the new chairs. Hope this assists, but a floor plan would help me.

Pendant light choice would usually be for a specific purpose so if you will move things around I would have a rethink. It may be possible to have a pendant with a long lead & hooks for the cord that would allow you to move it within a reasonable distance of the connection point. Maybe some general lighting might work better e.g. or two or three directional spotlights along edges or the ridge line & on dimmers if possible. Subtle strip lighting at the top of the grey wall & the addition of a feature decorative wall hanging & potted plants would look nice too.

I love industrial too it's raw.. clean lines..our place used to be a shop..terrace out the front then they built an extension out the back to house the printers..hence the high ceilings..we visited Japan just before renovating this place thus the Japan render..pendants were made by one of our client to say thank you..court yard etc

Looking at your lighting plan, it isn't not enough lights, it is where they are positioned. The three lights above island should be spaced directly above island for task lighting. Your plan has them across the kitchen, the same as other three in the middle of the kitchen. If you look at the photos that have been posted with pendant lights, they are all positioned over the island bench, not spread over ceiling. Hope your choice of lighting works well.
