Today, many buildings prioritize designing large windows to increase natural light and ventilation. However, if the door area is too large or uses completely transparent glass, the space may generate some inconveniences such as harsh sunlight, rising temperatures, glare and reduced privacy.
In particular, large windows in bedrooms or offices that receive too much direct sunlight can make users uncomfortable, affecting sleep and concentration. Therefore, instead of chasing after window area, it is necessary to balance the need for light, ventilation and comfort when using.
One of the simple solutions is to use curtains or blinds to adjust the amount of light. For large glass doors, especially glass doors from floor to ceiling, you should choose curtains that have appropriate anti-light and insulation capabilities, and can also be flexible in opening and closing at different times of the day.

Green plants placed near windows can also help reduce direct sunlight, create a comfortable feeling and increase the aesthetics of the space. However, it is necessary to choose plants that are suitable for lighting conditions, area and care needs.
In general, window design should be based on the actual function of the room. Combining reasonable window sizes with curtains, blinds and green trees will help control light, temperature, privacy and create a more comfortable living and working space.
In addition to the ability to control light, large windows also need to be calculated in terms of house direction and installation location. Windows facing West or Southwest often receive strong heat radiation in the afternoon, causing the room to heat up quickly. For these locations, you can use UV-blocking glass, heat-resistant glass or arrange an extra layer of sunscreen outside.
The size and opening style should also be suitable for the room area. Too large doors in a small space can cause visual imbalance, while rotating doors need enough space to avoid obstructing walkways or furniture.
In addition, attention should be paid to hygiene and maintenance. Large glass doors are prone to dust, fingerprints and need regular cleaning. If located in a high position, you should consider a safe cleaning plan right from the design stage.
