My sink is in the island, with enough room on either side of it for prep. It may not be the neatest position, though we do try to load the dishwasher as we go along (and, in times of high crisis, as when we have guests over, the worst mess gets transported to the sink in the butler's pantry and the door resolutely closed on it). The thing is, I can do prep while looking into the lounge to watch TV, chat to guests, or even to my better half. We tend not to use the bench as a breakfast bar, but there's plenty of room for a couple of people to sit at it nursing their drinks and chatting with host or hostess, should they be of a mind to do so. It's probably not the height of elegance or decor, but it works for us....Might be different if the kitchen had a window, but since it doesn't, I'd rather look at better half than at the wall.

go for practicality..I love cooking and my kitchen is very functional..you'll be cooking washing dishes daily..it will drive you nuts if it's not practical.. my mum's got hers on one end...massive space for food preps..it's great.. the sink is towards the window the other end towards the dining end thus with stools people tends to congregate that end to talk or help with food preps.

Velux Skylights which are 580mm wide are designed to fit between rafters or trusses that are spaced at 600mm centres, with the long side (780mm in your case) running with the fall of the roof, and not across the slope. You should look at your roof plan to work out where the slope, ridge and hips are, as your skylights need to work with the slope and can't cut across ridges or hips. The position will depend on the direction of the fall of your roof, and the spacing of the roof rafters or trusses. In some cases you can build a raked shaft to get them close to where you want, but you don't have enough information in this plan to provide an answer. I have a similar Velux skylight over my kitchen island and I would recommend you get one that can open as well as a block-out blind. Best of luck Dr Retro of Dr Retro House Calls

Option B. The living/dining have the northern orientation instead of the kitchen. The island bench makes for a more open plan kitchen that can be used by two people, with no tricky to reach corner cupboards. With only 60 sq.m you need to make it as open as possible without dividing up space. I think your in-laws are very lucky! Dr Retro of Dr Retro House Calls
