This looks like something that might work.

For the dining room, I think I'd orient the table 90 degrees from how it's drawn, and I would make it a drop leaf or gateleg table so that it can be made smaller when not being used for dining. I would embrace the idea that the entry is right in the middle of the living room, and bring the living room furniture out towards the fireplace so the fireplace is connected to the seating area. Maybe TV above fireplace. In that back corner where the sofa is drawn, I'd make that a small work/office space.

You can have something like this .Instead of T.V. in the drawing room you can shift it to your lounge area. Second option can be a library kind of a thing if you want a reading cum chill out section.

Yes sure ... we did something which I believe is a club of various ideas and expertise.. Though incomplete now , I will post what we have done till now. First we have around 8 feet appox glass 12 mm between the pillars. secondly we have three boxes 27" in height with focus halogens at the bottom. Now we will decorate these boxes with glass pebbles for awesome reflective / color effect. -I do need idea on what fillers can be used which will make me buy less glass pebbles ..else i would need at least 30kg plus of these pebbles. Thirdly we will now have glass film behind these 3 tall glasses to make it quite attractive and something which will look better with or without light. The idea is to add some golden plants in the middle i.e golden leaves and branches etc. -I would like more input on what films would look great behind these pillars. Or any other idea. I will definitely post once we are done with it.
