The bookcase placed on the balcony is best sealed. If glass is used, it is best to have shading function, otherwise books and CDs may fade because of too strong light. If the space is large, you can also put some fitness equipment, so that you can work and exercise correctly and live a healthy life.
If the balcony is changed into a study, then the ceiling of this balcony must not use a beam ceiling, which will bring a sense of oppression. In the feng shui of balcony study, people will be nervous and unable to concentrate on their study and work, which will bring people a feeling of relaxation.
Because the places with balconies have better lighting conditions and wider horizons, you can't sit by the window when setting up a desk. People should sit in chairs with their backs to the window, otherwise too much bright light will make people dizzy and will not help them with their studies.
The balcony should be sealed as a study. If the balcony is not well sealed, it will leak air in winter and reduce the indoor temperature. If you meet a windy day, you will let a lot of dust into the room. Whenever it rains, the window sash that is not tightly sealed will leak rain and get wet on the balcony.
If the balcony is used as a study and the balcony is connected with the interior, then the low wall under the window cannot be moved. In architecture, this kind of low wall is called "counterweight wall", which plays the role of supporting the balcony. If this wall is torn down, it will seriously affect the safety of the balcony. Therefore, the doors and windows between the bedroom and balcony can be removed during renovation, but the "counterweight wall" must not be moved.
