본 연구는 추사고택의 입지에 반영된 특징적인 모습을 전통적 입지관이라 할 수 있는 풍수적 관점에서 살펴보고자 한다. 또한 공간구성에 있어서 양택론의 한 부분을 차지하는 동·서사택의 구성과 특징 그리고 혈처와는 어떤 관련성을 가지고 있는지 살펴본다. 추사고택은 입지선정과 공간구성이 풍수이론에 바탕을 두고 이루어졌다는 것을 확인할 수 있다. 또한, 추사고택은 김한신이 영조로부터 직접 하사받았기 때문에 왕실문화가 곧바로 양반 사대부가에 이어져 왕실의 입지선정기준과 공간구성의 노하우가 당시 조선상류사회에서 어떻게 활용되고 있었는지 확인할 수 있다. 이를 통해 풍수는 단순히 발복론에 매몰되어 있던 것이 아니라, 입지와 공간구성을 통해 그 곳에 사는 사람을 더욱 빛나게 하는 역할과 아울러, 주변 환경이 보다 의미있는 역할을 수행하도록 하는데 있어서 합리적 방향성을 제시할 수 있다는 점까지도 확인할 수 있다.
This study is to investigate Feng shui feature that was the traditional positioning idea reflected from the House of Chusa. And the relationship between the context from theory of Dongsataek·Seosataek which is a kind of Yang-Taek Theory in Feng shui and the acupuncture point for propitious building position is also examined. In the House of Chusa, it was determined that the location selection and the spatial composition had been resulted from the base of Feng shui theory. And how the Feng shui influenced by royal family was utilized throughout high society of the Joseon Dynasty could be verified. Because the House of Chusa was directly granted by King Yeongjo when Kim Han-shin became a son-in-law of the king, royal family culture was able to intactly affect household of the gentry, and the condition of location selection and knowhow of spatial composition was also passed down. This means that Feng shui was not just used as means of favorable change in fortune but used to reveal the social status of the house resident through its location and spatial composition. And it is clear that Feng shui was used to suggest the rational direction with which semantic value of the surrounding circumstance was granted.
