Interior Space and Exhibition Design Stone Language Tranquility Residential Apartment by Po Feng Lee Stone Language Tranquility is a residential apartment interior design covering 132 square meters. The original kitchen walls were removed and replaced by an open plan layout. Terraco stone and aluminum strips were inlaid into the walls with special techniques, giving each wall a distinct expression. Black iron pieces, grey stone-patterned polished tiles and built-in furniture made with woodwork methods complete the interior. A partition screen was formed from the surname and name of the owner. Dark tones and stone surfaces create a calm atmosphere.
