Chrystalline Architect was trying to optimize the function of every part of this apartment, such as the space function, partition material and furniture, to accomodate all the owner activities. The extreme change-over is they replace the bathroom partition from standard brick wall into frameles glass to make it see-through, with roller blind to provide guest privacy. They use a frameles mirror as wall treatment on the side wall at the dining area to double sizing the visual space which also we put a hanging dining table with steel structure that is hidden in the back of the mirror panel. The dining area is designed as the favorite room for the owner to entertain their guests that extended with small sitting room. This area is connected to the bedroom through a hidden sliding door. The use of the door is to make the space more efficient. Along the “bridge” from dining area to the bedroom, they place the wardrobe with mirror panel sliding door in order to omit the narrow space in corridor.
