One of the comments from the interim is the scale of the shutter shouldn't be the as it should depends on how much light does that area needs. Therefore, I will change the size and the number of the shutters. For example, the living room area will change to 4 shutter because it needs more light for working on that area. Also the shutter can be controlled individually. So the sunlight will not directly go in when there is someone sleeping. The kitchen will have a bigger shutter than the bathroom as it is not necessary to have such big shutter on the top of bathroom. Also the presentation board have to make it looks more like a presentation board.
