NAVEL HOUSE, short for Narrow-Travel is a residential concept which is derived from the analogy of narrow land and client’s hobby, traveling to various areas for holiday or work.
Arcitect applied the concept of multi-mass building to analogize a trip when traveling from one region to another. There is one main building mass that has a function as developing space (1^st  floor - family room), solitary space (2^nd  floor - bedroom and main bathroom) & growth space (3^rd  floor – rooms for: photography, gaming and watching area) for the client. From the main building mass, owners can go to the building mass or other space connected with the corridor. There are four other building masses, mass A is the bedroom and maid’s bathroom on the 1^st  floor and balcony on the 2^nd  floor, mass B is the kitchen, breakfast area on the 1^st  floor and shower area on the 2^nd  floor, mass C is the onsen area on the 1^st  floor and the child's bedroom on the 2^nd  floor then mass D is the walk in closet area on the 1^st  floor and the child's bedroom on the 2^nd  floor.

The masses of the building provide new experience and interaction between the client and children, household assistants and colleagues. (a description of new experiences we get when meet other people or new places on our journey). Aside from the analogy concept, Architect also applies the concept of light and natural air circulation which enter through openings in each room and glass skylights which also connecting corridor on the 2^nd floor. In material aspect, to create a various spaces experience like traveling experience, we combine different material like split stones and white pebble stones in the corridor and balcony areas, exposed cement, wood and ceramics in every building mass.

Meanwhile, in the façade area, Architect explored by creating an inverted trapezoidal shape with 2 different masses of building orientation and different material. The representation of the trapezoidal shape is an analogy from the concept of main building mess which is growing area for the client. While the difference between mass orientation and building material are representation of the experience diversity while traveling
