What is the inspiration for your design?
Here is the inspiration from two lines of the poem “Khúc Hát Ru Những Em Bé Lớn Trên Lưng Mẹ”. “Mặt trời của bắp thì nằm trên đồi Mặt trời của mẹ em nằm trên lưng”
When you sleep peacefully on my mother's back, I will firmly step through the fatigue, so that you will grow up and move forward as strong as you used to. That is Nguyen Khoa Diem's comprehensive picture of a big family loving each other.
The image of a large family of 3 generations, living under the same roof is like the image of terraced fields. The large lower step will be a pedestal for the small step above to develop, layers and layers of layers forming a solid green mountain.
Borrowing that image, I built the concept of 'Lullaby on the fields', which has a deep meaning, shows the customer's aesthetics, and is both airy in terms of feeling, and convenient in terms of work power.

How does the design fulfill the need of the target users?
The problems posed: The family of 3generations, living in an apartment, belongs to the middle class and above, and has aesthetics
Situation in Vietnam: The living area is very limited => so the bathroom and WC space are small, placed in a place that lacks natural light and is not ventilated.
Solution:

Solution: There is a standing platform in the sink area

How does the design fulfill the design challenge?

How does the choice of products contribute to the purpose of the design?
- The bathroom will be a paradise to relax everyone, so it is necessary to have a bathtub for the family: For the elderly, having difficulty walking, they can sit and use the shower right in the bathtub, and children will have lots of fun, enjoyment, and stimulation with bathtime and playtime.
- Using bath taps and basin taps, easily adjust the temperature based on family member's preferences, and the ability to turn on or raise the faucets helps children recognize where hot and cold water is located.
- Use BTW Toilet This hides and removes the entire tank and plumbing from view saving space.
With those options, it will be effective in terms of function and space-saving.
