Interpretive architectural study of the catalogued property.
2620 Rock Creek Drive NW, Washington, DC 20008
A long brick house on Rock Creek Drive, with a pedimented doorway and two tall chimneys on its Woodland Drive side. Built in 1990, it stands behind clipped hedges and a stone garden wall.
| Fact | Value | Basis and sources |
|---|---|---|
| Constructed | 1990 | estimated; CAMA AYB; effective year 2017 is not construction. |
| Acquired by Singapore | Not Verified | unverified Official sale/deed dates are missing or placeholders. A secondary listing reports an April 1992 sale, while CFA mentions an unnamed buyer; neither establishes the deed grantee. |
| Neighborhood | Woodland-Normanstone | verified; Standardize the established geographic neighborhood name for 2620 Rock Creek Drive NW; normalize the existing Woodland Normanstone spelling without changing the geographic assignment. |
| Architect | Not Verified | unverified CAMA, the address record and reviewed CFA site-history material do not identify the house’s architect; targeted exact-address research did not resolve the attribution. |
| Rooms | 15 | verified; Current DC residential CAMA ROOMS for the identified dwelling; this assessor count is distinct from bedrooms, bathrooms or the number of modeled room studies. |
| Floor area | 5,600 sq ft | verified; Recorded DC CAMA building area; preserve the source field and building scope. |
| Site area | 11,000 sq ft | verified; Two contiguous, nonoverlapping Singapore-owned parcels: main house parcel 2140/0046, 9,774 sq ft, plus southwest edge parcel 2140/0847, 1,213 sq ft. Sum 10,987 sq ft. Use the current assessment LANDAREA fields, without substituting the GIS calculated-area field. |
| 2026 Value | $7.1M | verified; Current 2026 ITSPE ASSESSMENT sum across the same two-parcel residence estate: 2140/0046 at $7,054,630 plus 2140/0847 at $25,530. Both records have DELCODE N and CY1YEAR 2026; the southwest strip has PHASEBUILD 0. Current assessed estate total. |
| Diplomatic use | 2007 | documented-by; Washington Life’s dated October 2007 Embassy Row directory explicitly lists Ambassador Chan Heng Chee’s residence at 2620 Rock Creek Drive. Earliest dated occupancy evidence at this address. The 1992 sale and CFA inspection establish ownership and condition; the move-in date remains unresolved. An earlier Clinton Library list also names Chan at the property but lacks a verified document date and is not used to assign a year. |
Scope and Evidence
DC residential records list 15 rooms, including five bedrooms, and separately record eight full bathrooms and one half bathroom. The 5,625 sq ft figure is recorded gross building area.
The $5,691,300 Zillow Zestimate supplied on 22 October 2026 is a market estimate. It is separate from the official 2026 DC assessment of $7,080,160 for the two-parcel estate; the quoted Zestimate has not been independently verified.
The exterior follows the supplied July 2025 and November 2022 street views and aerial views reviewed on 22 October 2026. The official DC footprint anchors the main rectangle at approximately 24.3 by 10.9 metres. Heights, planting and details hidden on the rear and left side are approximated.
Land and assessment cover main parcel 2140 0046 and adjoining strip 2140 0847 together: 10,987 sq ft and $7,080,160. The strip has no building area.
