Interior Space and Exhibition Design Meridiana Residence by Tsu-Wei Chang Meridiana is a duplex residential interior design covering 185.1 square meters. The layout separates social areas downstairs from private areas upstairs. Curved walkways guide movement and change the position of people in relation to daylight. Reflective materials at the ends of the walkways extend the reach of light. The walls carry grooves of 5 and 7 centimeters, along with sponged and scraped textures, so light and shadow form clear lines. Materials include marble, glass and metal. The intent is to spread limited natural light through the whole home.
