Baruah Bhavan Guest House has its own interesting history. Uzanbazar at the advent of the British rule had a few hillocks some of which are still in existence. The road west of the present bazaar called Naujan Road was a rivulet that flowed right from Khonamukh via Deepor Beel, Solabeel and Jurpukhuri. The Latasil field was a big pond and a godhuli (evening) bazaar orginally sprouted by its east bank in front of what now is film directors Nip Barua's and Brojen Barua's ancestral home. The market place near this pond became a nuisance with drunken brawls every evening. This became unacceptable and so the bazaar was shifted to its present location. By 1898 the pond at Latasil was filled up by cutting the northern and western portions of what was known as Fatik Chandra Barua's and Manik Chandra Barua's tilla (hillock). This flat northern portion of the hillock is where Baruah Bhavan is located and in the past it has served as the tea factory of Manik Chandra Barua's tea garden. Manik Chandra was Fatik Chandra's younger brother. He had no sons but two daughters. His elder daughter was married to Kaliram Barua, Mauzadar (tax collector of a teritory) of Palasbari, who inherited half of Manik Chandra's extensive property in Guwahati. Both Dr. Birinchi Kumar Barua's elder brothers Dr. Lalit Kumar Barua and Sushil Kumar Barooah married Kaliram Barua's daughters. This property in Uzanbazar, which at one time served as Manik Chandra's tea factory, was bought by Dr.Birinchi Kumar Barua in 1938 from his sister-in-law Kusum Barua, wife of Dr. Lalit Kumar Barua and mother of historian Dr. Nirode Kumar Barooah.
Whilst Dr. Birinchi Kumar Barua was living in the original wooden structure which was then over 100 years old, numerous luminaries stayed here. They included the erstwhile Congress Party President, Dev Kanta Barooah who was Dr. Birinchi Kumar Barua's first cousin, Suresh Rajkhowa, Hem Barua the eminent politician, Aswini Barkakoty of the Gauhati University, Jatin Duara the famous poet and many more. Dr. Birinchi Kumar Barua demolished the original wooden structure and constructed a modern cement concrete building in 1955. Thereafter many famous persons visited him at Baruah Bhavan. They included Central Ministers Humayun Kabir and Mainul Haque Choudhury, Chief Ministers of Assam Bimala Prasad Chaliha, Hiteswar Saikia, Atulya Ghosh of West Bengal, Assam State Ministers Debeswar Sarma, Omiya Kumar Das, Baidyanath Mukherjee and Ramesh Chandra Barooah who was Dr. Birinchi Kumar Barua's brother-in-law, to name a few. Famous renowed literary persons such as Ambikagiri Raichoudhury, Maheswar Neog, Satyen Sarma, Nirmal Prava Bordoloi, Prafulla Dutta Goswami, Prabhakar Machwe of Maharashtra and B.C.Pavate of Karnataka amongst others visited Dr. Birinchi Kumar Barua from time to time.
After Dr. Birinchi Kumar Barua's death in 1964, this property was inherited by his two sons, Raj Baruah and Manju Barua, who owns the famous wildlife resort in Kaziranga called "Wild Grass". Later in 2009 Manju Barua sold his share of the property to his elder brother Raj Baruah, who made extensive renovations of the building to transform it to its present state.
