One possibility would be to swap the living room and the dining room. Since the current living room is larger than the current dining room you could still keep some comfortable seating (couch and upholstered chairs?) against the front wall for a keeping room/dining concept. Then your new dining areas (kitchen and dining room) and living areas (living and drawing room) would have good flow between them, which would work well both for family and entertaining. You could also add some builtin bookshelves in the drawing room or new living room to create a library area to add another fun element to the living areas. These bookshelves could be against the long walls in the drawing room, around the window with a window seat in the living room (former dining room), or built to create some separation in the open area between the drawing room and living room/stair area. Your plan seems to show some sort of builtin there, but I'm not sure what it is.

This arrangement works much better, but some adjustments are needed to make it work. First, the fireplace grouping needs to be tightened. It crowds the dining area and you need a passageway behind the couch. Turn the rug lengthwise, parallel to the fireplace. Pull the large couch about 2 1/2 feet closer to the fireplace, and place the two chairs and loveseat on the ends of the rug, and pull them closer together. This will give you a more intimate conversation area, and not impose on the other areas of the room. Remove that floor lamp from behind the couch. If you need the light in that area, put it by the fireplace. Also, the stereo system on the mantel needs to find another home. Maybe it can go IN the fireplace instead. At the other end of the room, I think the arrangement would look better if the seating were rotated 90 degrees. Keep the rug and coffee table in its current configuration, place the sofa either facing the window or with its back to the window, and put the two chairs opposite it. Finally, the dining area. Now that you've moved the big leather chairs, you should have enough room. Your rug is too small. It should be big enough to give you at least a 2 ft. border all the way around when the chairs are pushed in. And it's a really beautiful table; please uncover it. I can't see what kind of lighting that area has. It really needs a pendant or chandelier hanging directly over the table.

I think a comfortable distance between the island and the counter is around 42". It seems that you have only 30" between your cook top and the counter. I might be a little too tight. The wall between the entrance and the kitchen could be 4' long instead of 6', you would then be able to move the island a foot which would give you more room between the cook top and the island. Could you switch the location of the toilet and vanity in your dad's bathroom so your enter facing a vanity instead of a toilet which is a lot nicer.

Sophie, Patricia you are right cleaning the crystals would be a hell of a job. Hence I would like to look at designs like the other pic I attached which is I believe from the e.ion range of Falmec. As I have mentioned before this is a second chimney. The primary chimney hood is above my gas job in the kitchen countertop and is the main and daily area for cooking. This is the secondary area which I plan to use for some quick heating, occasional stir fry etc. The pendant chimneys that I have come across in brands like Elica and Falmec do not require ducting. The filter needs to be changed every 6 months or more. With my kind of usage I am assuming I would need to change it even later. What I am looking for is different brands which have pendant chimneys. Right now I am only aware of Elica and Falmec. I know Siemens and Bosch don't have it. Siemens has 2 models which are like a flat rectangular panel to be attached to the ceiling or false ceiling. But the cost is same as the Falmec chimney. My only respite may be the cylindrical Isola chimney models from Faber or even Hafele which are ip within budget.
