the attachment is no where to be found......Please try again...........

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.

Hello, You can swap the dining and living setup . But having a temple in the current dining area would pose you another challenge art to space. IMO, current setup seems good enough. You can have a temple on the adjacent wall to main door. Thanks, Nitin CORNERSTONE DESIGNS, Bangalore
