St Helen's House is a Grade I listed building. situated in King Street, Derby, England. Now leased as offices, it has been used in the past as a private residence and as an educational establishment. In 2013, renovation of the main house was completed. Originally it was planned to convert both St. Helen's House and the Pearson Building into a luxury hotel, with an adjoining crescent of new apartments. Due to the economic situation in 2011 this plan was changed, and it was decided to convert the building into an office instead. Renovation of the Pearson Building began in 2020 to convert its ground and first floors into commercial units and the upper floor into apartments. In 2019 several of the associated building were demolished to make way for the Kings Crescent Apartments. Construction St Helen's House was built between 1766 and 1767 for alderman John Gisborne (of Yoxall Lodge, Staffordshire). The house was built in the Palladian style by architect Joseph Pickford. It originally stood in of parkland. It has been described by Maxwell Craven, for the Georgian Group of London, as "one of the few surviving purpose-built Georgian gentleman’s town houses of this size and quality outside London.". His report details the construction of the House along with the alterations and extensions added by William Strutt (1756–1830). Strutt family In 1801, the house was purchased by William Strutt, the eldest son of Jedediah Strutt (a pioneer in the cotton and hosier industry). Following William's death, the house passed to his son Edward, who became MP and Alderman of Derby. He was created Edward Strutt, 1st Baron Belper in 1846. His son, Henry Strutt, 2nd Baron Belper was born in the St. Helen's House in 1840. Educational use In 1860 Edward Strutt offered to sell the house to the governors of Derby School. Initially the school could not afford to buy the house, but Edward Strutt, "being desirous of promoting the cause of education in Derby" loaned the house for free, on a temporary basis. The school moved to the house in January 1861 and purchased it from Strutt in 1863, for £3,300. £1,300 of this came from a public subscription and £2,000 from a mortgage raised by Derby Corporation. During World War II the school was evacuated and the buildings were occupied by the Ordnance Survey organisation to undertake the creation of maps used by Allied Forces. In
