The center of the domain was the eponymous Landhuis Tandjong West, an eighteenth-century Dutch colonial manor house.
[1] Duurkoop utilized the estate as a farmland, where he kept about 5 thousand cattle producing milk and meat for the company in forted Batavia.
His wife Johanna Adriana Christina Duurkoop remarried with Conraag Johnas and moved to Japan for a military duty.
Ver Huell described the building as "standing across the high banks of the river, the beautiful Landhuis Tanjong-West, surrounded by a forest of coconut trees... at the foot of these heights lay a lovely green meadow, covered with numerous grazing herd of cattle, here and there a group of dark tamarind trees - in the foreground the richest nature one can imagine".
[3] In the 1901 map of Lenteng Agung, the manor house as described in the notes of Ver Huell still exist, being located in close proximity to the Landhuis Tandjong Oost.
[9] The land where the manor house used to stand as indicated in the 1901 map is currently owned by the government of Jakarta and used for the Pusling (mobile health center) Tanjung Barat.
