Koya No Sumika is a minimalist extension for a young couple’s traditional one-storey house located in Yaizu, Japan and designed by Tokyo-based mA-style.
‘Koya No Sumika’ provides a retreat space for the clients for sleeping and quiet time, while the kitchen, bathroom, main living space and children’s bedrooms remain shared with the main house, reinforcing strong ties to the family.
A simple extension may enable each of the house's residents to live completely separated, but the relationship between the families and the connection with the main house might be lost. Therefore, by utilizing the functions for living in the main house, the extension is designed as a minimum living space, and pursues both maintaining distance and retaining fertile relationships.
The extension is attached by a connecting-corridor on the west side of the main house. This enables the residents to switch their mindset before entering into the other living space, and the common garden maintains a proper sense of distance.
By relying on the main house for the large kitchen, bathroom, and future children's room, only a few functions for a living space are required for the extended part.
