Built in 1915, Nai Lert Park Heritage Home was designed by Phraya Bhakdinorasresth (Lert Sresthaputra), which was his permanent residence that he shared with his beloved wife, Khunying Sinn (Thevit) and his daughter Thanpuying Lursakdi Sampatisiri who later married Khun Binich Sampatisiri.

Nai Lert bought the land along Saen Saep Canal and planned to build a unique teakwood abode where they could relax and have friends over to visit on the weekends in the confines of a lush garden. The Nai Lert family home were opened to the public in 1915. It was the first western-style public park in Siam, even before Bangkok’s Lumpini Park was opened. Scout camps and other activities were held in the grounds, fondly referred to by locals as “Nai Lert Park”
