Plans to convert the building into a hotel were scrapped following the economic downturn and the house was converted into offices instead, the first company taking possession in 2013. The first headmaster 'Norman' Elliott and deputy headmaster W.O. Butler of Derby School at Moorway Lane, Littleover both transferred from the St Helen's House site. Mr Elliott retired in 1979 and died in late July 2012. On arrival at the new school in 1966, its playing fields were found to be still full of stones, so in the beginning the boys were bussed across town to Parker’s Piece, off City Road at Chester Green, for sports. The traditions of the older boys, uprooted from St Helen's House, influenced the new boys. The running of the school was still steeped in history, with praepostors and monitors, and with the houses still competing for the Cock House trophy. Latin remained an important subject. Masters (teachers) still dressed in suits, with gowns and mortar boards, and used corporal punishment, sometimes publicly after lessons. There was a strict dress code, and sixth formers could wear boaters on summer days. Lockers did not need locks. Older boys expected respect and obedience from younger boys, although not fagging. Praeposters and monitors could administer punishment. They also had their own rooms, and later the use of the Pavilion, off limits to masters and the lower forms. The new school had purpose-built Fives courts, where gloved fights between boys with grudges were tolerated as a gentlemanly way of settling disputes. The school continued as a single-sex grammar school until 1972, when it was taken over as a maintained school by Derbyshire County Council, which converted it into a co-educational comprehensive school and greatly increased its size, in buildings and pupils. At this point, it was still Derby School. However, in 1989 the County Council decided to close Derby School and to make the headmaster redundant. A new school fully comprehensive and co-educational was created called Derby Moor Community School with a new head and governing body but with many of the old school's staff and students. Then for a period of time until 2017 it was known as Derby Moor Community Sports College Trust, was opened at the Moorway Lane site. In terms of legal identity, this was not the same school, but in some ways it was its successor. Changes in education in the early Twenty First Century saw a further development in 2017 when the school on the site became the Derby Moor Academy.
