Sir John Sonae(1753-1837) was the most original English architect of 19c. his extremely personal style is superficially neo-classical but, romantic or ' picturesque' in its complicated and unexpected spatial interplay. The Soane's style was one of the curiosities of European architecture. Sir John Soane, like mackintosh, was best known for his interior spaces. He used his own house as a laboratory of spatial experimentation to develop his spatial ideas. The objective of this study was to examine his architectural style through his various architectural works and analyze . The Soane's Museum (his house, No.12.13.14 Lincoln's Inn Fields. London, UK) in order to find inter design elements which represent the best of Soane's interior design effects. As a result , this study found that Soane held no theories as to proportion . It gives the conditon of the building's freedom. He shows the ' primitivism facade and the simple neoclassical symmetry exterior arrangement. As interior design elements he used the layered structure, the natural skylight, the pendentive dome, the space in space, the pictures que style. These elements create magical interior space of the Sonane's Museum. THe spatial intrigue is further enhanced by various degrees of lighting that additionally emphasize the three-dimensional quality of the object loaded walls and piers. One can always look through to space beyond many individual object, both horizontally and vertically. These interior elements can be used for the modern interior design development in order to create the expansion of space and the territoriality of space.
