appears to have arrived with the culverting of Hackney Brook in about 1847, which is reputed to run in a large cast iron tube through the back gardens, before turning South down Isabella Road to join the main sewer network at Old Ford. Lead was stolen from the roof, of one of the houses under construction, on the night of 22 December 1808. The perpetrator was sentenced to be publicly whipped in Hackney Village and to one year in the House of Correction. At each end of the terrace were two yards, for carriages and horses. The one adjacent to Sutton House was for many years a car breakers and repair garage (Taiko Autos) but has been acquired by the National Trust and turned into a garden for visitors called the Breaker's Yard, which includes features commemorating its former use. Hackney Grammar school The Hackney Proprietary Grammar school opened in 1830, on the north side of the street, adjacent to St John's churchyard, providing education for 130 boys. The Madras system was used, whereby elder boys were appointed monitors to take responsibility for the younger boys. The school caused controversy for the number of non-conformist teachers and for a notorious ban on the sons of shopkeepers. By 1840, the school had declined to an entry of 50 pupils and was amalgamated with the Church of England Grammar school (on a site now occupied by a part of the Pembury Estate). The school building became a private building known as Sutton Lodge, and by the 1950s was demolished to extend the adjacent Metal Box factory. Later use The north side of the street consists of villas built in 1820, also listed. There are two small blocks of flats at either end of the north side, filling in gaps in the terrace, but in keeping with the villas. The street survives intact, as it remained in the ownership of Charterhouse into the 20th century. Then it passed to the Metal Box Company, who developed a factory behind the buildings on the north side. The (unsightly) office block on the north-western corner was built to service the factory, on the site of the former Hackney Grammar School. The core of the Metal Box site became the award-winning Sutton Square, private development. Originally, the street was occupied by wealthy merchants and gentry, including at least one mayor of Hackney and the exiled German poet
