One Roof House in Seongnam

Location: 526-8, Pangyo-dong, Seongnam-dong, Seongnam, South Korea

Design: mlnp architects

One Roof House is located in Pan-gyo, a residential area in the suburb of Seoul. This building focuses on spatial arrangement and sectional plan rather than exteriors.

One Roof House

One Roof is divided into three different spaces, each having different characters in both horizontal and vertical layout.
In horizontal layout, One Roof suggests to separate spaces for parents and children, with the family space connecting them together on the rectangular-shaped ground. This layout achieves true privacy between family members while making better use of family space.


In vertical layout; 1) the ground floor – the communal space having a grand living room open to the front and the back with a bench to be shared with neighbors, 2) the second floor – the private area with an exclusive family room for promoting affinity between family members, and stair-shaped playground for children, and 3) the attic – an intimate space with a hobby room for parents, a library for children and a garden open to the sky.

One Roof House

Each individual space can be well lighted and ventilated even in dense residential areas by applying an opening to the sky and careful layout for windows and doors.


The ground floor is finished with white-colored exterior insulation finishing wall, and the second floor and rooftop are done with dark metal sheet in vertical pattern to stress aesthetic tension in the gable roof.

One Roof House

The triangular-shaped window facing south uses 32 millimeters thick polycarbonate that allows natural light to gently come through inside during day time, while offering unique exterior landscape during night time with the structure seen as shadow with delicate light coming from the inside.
