關於堅尼地道28號﹐找到小小資料﹕

The Hong Kong Design Centre has its headquarters at 28 Kennedy Road, well known before the
1997 handover as the Joint Liaison Group offices. The building is an elegant colonial-era mansion having been home at different times to the Banque De L’Indo Chine (1905), the Japanese Residents Association (1931), and various educational institutions. It was acquired by the Hong Kong government in 1954.

從外形上﹐我認為26及28號是不同期的建築。 如它們是﹐兩座建築物會一同被列為文物受保護(28號是三級文物)。26號看來是較新的。
