The Mate’s Guide of 1903 describes Hart House as a large boarding school which moved to Burnham from Cornwall in 1893. On arrival in Burnham its principal was Rev. J. Thompson, who had been succeeded by his son Mr H. J. Ker Thompson by the time of the guide.
The house, says the guide, “is built in the Georgian style and stands in the midst of extensive and beautiful grounds, over eight acres in extent. The house is approached by an avenue of fine trees which forms an interesting feature of the Berrow Road. A large number of pupils have passed through the school which takes a very high position among the similar institutions of the county of Somerset.”
