"Natural Flow" is a home crafted with the vision of creating a place where family memories and belongings can be treasured, inherited, and shared. Designed for a couple and their three children, this residence embodies the essence of family living, with future adaptability in mind.

The design meticulously calculates the maximum volume that the building can occupy, taking into account the site’s size and north-south height difference. The top floor features a single- room space where the family can gather and spend time freely. This area includes a kitchen, desk, large sofa, wood stove, and a spacious terrace with a beautiful park view to the west. Additionally, there is a sauna with a small terrace, creating a harmonious space where each family member can engage in their activities while still being together.

The second floor houses the main entrance and individual rooms. A shared family closet consolidates storage into one area, leading to a tunnel-like passage to a small free space. This flexible area, with two levels, is designed for various uses such as family gatherings, a theater, or a guest room, adapting to the family’s changing needs. The first floor serves as a family archive and library, designed to be a serene and comfortable space for preserving and sharing family memories, ensuring they can be passed down to future generations.

Anticipating the future when the children have moved out, the design allows for the living space to be downsized, catering to just the couple. Considering the connection with the park planned to be developed on the west side of the site in the near future, the first floor is designed with sufficient facility space for potential commercial use, with a structural plan allowing for direct access from the sidewalk. The plan involves gradually reducing the number of occupied floors, ultimately leaving only the third floor for the couple to live compactly.

Within the building, indirect air conditioning is implemented on all floors, designed to gently circulate comfortable air throughout the building, aiming for a natural air conditioning that is imperceptible. This was supported by strategic window placement, comprehensive insulation planning, air conditioning simulations, and design. The structure employs a concrete wall system to eliminate unnecessary space wasted by columns, ensuring efficient use of space right to the edges.
