Hi Ardhendu, Double heights add a lot of light and volume to a space. However, a lot depends on the overall planning of the rooms around it and the resulting size of the slab cut out for the double height. If you are only left with a small shaft like space, it reflects poorly on the design. Also, the placement of the slab cut out is crucial in a living space considering movement, furniture placement, lighting and ventilation. It would be great if you could send us the proposed layout of your house for us to comment better. Else, please consult a local architect. All the best! Regards, RnD Atelier Nagpur
