It was there that she wrote her best known stories, "The Mangas", "In the days of the Bulgarslayer", "The Secrets of the Swamp", "Crazy Antonis", and "The Life of Chris". It was there that she kept her diary -parts of which have been published- with its important testimonies about her own life and the tumultuous contemporary history of Greece. Αnd there where she carried on her correspondence about the contentious issue of education with individuals such as Yannis Psycharis, Kostis Palamas, Manolis Triantafyllidis, and Dimitris Glenos. In this house, the Delta family frequently hosted leading politicians and intellectuals, and it was after spending the evening there on 6 July 1933 that Eleftherios Venizelos survived one of the attempts on his life.
The Delta house is a characteristic example of the mature neoclassical style of the early 20th century, with a number of eclectic features borrowed from medieval architecture, including the typically Athenian feature of a tower staircase. The interior is spare, with wood panelling, but without the plaster-of-Paris ornamentation common to bourgeois houses of the period. The Delta family built an addition at the south-west corner of the house in order to enlarge the author’s work space and they installed an external elevator. These alterations do not affect the character or the morphology of the original building.
The restoration of the building began in 1992 according to the architectural study by G. Plessas and A. Zannas.
