Scope and Evidence

The property’s identity is established by the official 2026 embassy Independence Day report, an address-specific July 2026 reception report, and DC ownership records naming the Embassy of the Republic of Indonesia.

The Office of Planning identifies the estate and its 1950 diplomatic acquisition. The exact architect, deed date and first occupation day remain unresolved.

The model follows the supplied aerial views and exterior photographs: the stone and timber house, reception wing, courtyard portico, dormers and rear terrace. Dimensions and the compact landscape crop are estimates; the crop is not the surveyed estate boundary.
