What is 'Sanggojae' (상고재)? It is the house used in the Korean drama Personal Taste (also known as Perfect Match in the Philippines).
Based on my online research, the original name of the house is known as 'Yeorangjae' (여랑재). It is found in the middle of Bukchon Hanok area.
The name, 'Bukchon,' which literally translates to 'northern village,' came about as the neighborhoods that the village covers lie to the north of the two significant Seoul landmarks, Cheonggyecheon Stream and Jongno. Today, many of these hanoks operate as cultural centers, guesthouses, restaurants and tea houses, providing an opportunity to experience, learn and immerse in Korean traditional culture. [Reference]
