Case 1. To convert a Japanese-style room to a living room with wooden flooring, café-like LDK space

This renovation was carried out when purchasing a pre-owned apartment.  The stand-alone kitchen was converted into a face-to-face kitchen, and the existing Japanese-style room was converted into a living room.  Interior windows and vertical lattice fittings let in light. The fittings, floors and furniture are made of softly colored wood, with accents of iron and tile textures.  Although any major changes to the floor plan have not been conducted, the result is bright and spacious living spaces.
