Very small kitchen you could do an under cabinet ventless exhaust that has filters that you will nedd to change periodically but that way you will have a bit more cabinet space.

@corner Stone designs. sorry if I had given an impression it mud slinging. but objectively speaking the suggestion to go for a chimney just because someone asked for it instead of addressing the real issue us not what I intended to do. one has to understand all the negatives as well veggie going in for a decision . just like you have the right to suggest there is nothing wrong in pointing out the issues in the proposed solution. none of us are internet warriors but most of us are "sold" items that we will never need in our life by creating an illusion. I know that dinner call it business but I am not in such one and I have the luxury to call a spade a spade. Even now the person who asked for is not sure in what they want but they think that a chimney will solve the issue. engineering doesn't work that way. unless we know what the real issue us, which isn't clear if it is the smoke or the smell and the your of food cooked, the frequency, the 80/20 utility of the kitchen we are not even close to understanding the problem. my intent is to emphasize the importance of understanding the problem and then look for issue and not provide a ready made solution. we can all suggest something by seeing a picture that fire will come and catch the chef if it is located in the window but do you think that what you say is practical. you may construct this as much slinging be as a novice I have a genuine question. how many houses have such a fire accident. we don't even know if the stove is electric or gas. if it is electric then they just no question of fire. so I encourage you to objectively approach and not see this as a mud slinging thing as that's not the point.

Arun , Gas pipes and meters are often hidden beneath the counter and wall cabinets. Sometimes re-laying the piping is required. You can post your kitchen pics with floor plan for further details.

Sorry Rupal shah if u get hurt.. But I thought I'm just getting ideas from the experts to see what possibilities... Not sure why u feel it that way. May be i posted my question wrongly.? I will rephrase.. The wall is constructed till sajja level.. and the shelves from inside r yet to be made. I'm trying to check what options r available to get more lighting and ventilation in kitchen? Can a window be still made in parking side wall with compromising shelves for the window area? Or would ventilators look good which opens in parking area? Anything else? Thanks
