ABSTRACT
This Research aims to develop prototypes of handrails made of monolithic synthetic wood which can be used as multi-purpose organizing material in interior design. 
Wood material is especially suit to handrails for its smooth, soft and warm touch. The material also accepts wide range of manufacturing methods and has great potential of design possibilities.  
The prototypes developed in this research were shown in Fig.1-3, which can be classified into 3 types as, 1) Full web type, 2) Open web type with fixing brackets and 3) Open web type with mill carved openings. Although each type has its own advantages, the lattermost type could be considered to be most applicable and suitable to wide range of different purposes. 
Design application models were developed as shown in Fig.4-7. All the design tries to realize the possibilities of the handrail to organize the coherent design of corridor interior. It is used as handrails, as door handles, as back panel of benches and so on, and continues through the way. 
The possible manufacturing method and machines were shown in Fig. 8-17. In addition to synthetic wood producing machines such as finger-joint saw and gluing / pressing machines, multi-head moulders and NC routers should be the main machinery to prepare the unique section of the proposed handrails.
As a conclusion, the proposed prototypes can provide the new design possibility of organizing interior design as “Functional Moulding Band” in a modern way, and can be manufactured with certain combination of existing and newly developed machinery. The demand of such material could be huge for further development of universal ergo-design in architecture.
