Moojen's plan was later extensively modified by F.J. Kubatz as part of the city's next development plan. In the Kubatz plan, the street pattern was changed and a small pond (Situ Lembang) was added to the east of the central park area, originally named "Bisschooplein" after G.J. Bishop, mayor of Batavia (1916-1920). Other architects contributed to the character of Menteng Residential Area through landmarks. Architect Ghijsels designed Indies-styled houses, St. Paul's Church and the adjacent Logegebouw, which was the office of the "burgemester", centrally positioned and facing the central park (now the Indonesian national development planning board (BAPPENAS)). Ghijsels's colleagues in the AIA, architect J.F.L. Blankenberg, designed some lavish residences in Menteng between 1926 and 1939 (after Ghijsels had returned to the Netherlands) e.g. the home of the owner of Wellenstein & Krausse Company (1926, now the residence of the US Ambassador to Indonesia), home of the Governor of Jakarta (1939), and several lavish residences for local businessmen along Jalan Imam Bonjol (one of which is now the National Proclamation Museum).
