Not a giant fan of windows behind the range, but it is what it is...so...most exhaust fan manufacturers and range manufacturers have determined the required air flow (cubic feet per minute - CFM) as well as the optimum distance from top of cooking surface to bottom of hood. Start by checking the specifications for CFM and distance from cooktop with the range manufacturer. Not sure of your location, but here in the States the IRC requires exhaust fans for kitchen, bath and laundry. Some areas, although they have adopted the Code, do not enforce it. But if broiling pork chops ever happens at your place...you sort of want it.

I think the white trim gives it a much more contemporary look. It's more work to have it done in a different color, but the overall look is cleaner.

I'll start with what I personally don't like , but obviously some people do -- The two couches look like they match ( which is good ) and in a green leather ( again good ) , but the browny olive carpet doesn't really work . Than you have a green fabric rolled arm chair , that is 100 years old in design and fabric design -- just because it is green , doesn't mean it works with the couches , because it doesn't . The chair that does tie in ( the green leather one ) is in a funny spot , but I also think it would look funny between the 2 couches . Then you have a nice armchair 'up the top' , and I think/hope that the fabric matches the dining chairs ? Then the TV area looks 'busy' . Probably the least of your worries , just an observation . SO -- I'd move the rolled arm chair right out of the room . The couch along the window I'd move around to beside the other one , and then the single green leather around by the window , so you have a green leather semi-circle . Personally , I still don't like the leather and the the carpet 'clash' , so I'd like to change the carpet ( or the lounge suite if you are wanting a change there -- although you'd have to go maybe that 'shooting lounge' aged brown leather if you want to keep the carpet ? ) . 'Up the top' by the bookcases I'd try and get a second chair the same as the other wheat/grey one , and add a coffee table -- so you have a conversation area , and a lower lounge/TV area . If it was me , I'd probably remove and wall in the 2 'left-hand' side windows -- the one that the blind is closed and I suspect is closed most of the time , and the one behind the TV . I'd then wall mount the TV ( if done professionally , you get the power and aerial all hidden ) so it cleans up that area , but that does start getting costier .
