The landscaped lawns feature a small stupa containing the ashes of Ayi Thubten Wongmo and a white chorten commemorating the late Rani Chuni.

The room of the late Rani Chuni is kept as originally furnished with Bhutanese chodems (carved tables), woven materials, books, and other artifacts.

[14] Topgay Raja himself married a Sikkimese princess,[14][15] fathering Jigme Palden Dorji, future Prime Minister.

Another of Topgay Dorji's sons, Ugyen, was recognized as a lama at Bhutan House as a young boy.

From here, Sonam Topgay Dorji was Agent for Foreign Relations for the Royal Government, as well as Governor of Haa (1917-1924), directly abutting the estate.

[14] After two generations of growing influence, the sister of Prime Minister Jigme Palden Dorji – the daughter of Topgay Raja – married the Third King of Bhutan, creating a new bond so prominent as to cause some discontent among other Bhutanese families.

[13] Because of the influence of the Dorji family and its members' fluency in English, Bhutan House was the sole outlet for communication between the government and the outside world.

[2] Topgay's professional and personal contacts with India as it gained independence from the British Empire proved invaluable to Bhutan as it sought to modernize and develop.

Once the Dalai Lama returned to Tibet, he sent Bhutan House a large gilded bronze statue of himself for the attached lhakhang (temple) he dubbed Dechen Gatsal ("The Happy Garden of Great Bliss").

After the death of his host, the Dalai Lama gave the Dorji family a kashog (decree) written on yellow silk and sealed with his great seal; the kashog expressed his gratitude for the hospitality he received at Bhutan House, and for the efforts of the Dorji family to aid the Tibetan people.
