The practice, which was set up by former David Miller Architects project architect David Mimram in 2017, is also revamping the existing Padangle House in Kingsland Road, upon which the homes will sit.The scheme was originally submitted in 2021 during the Covid-19 pandemic at a time when Hackney Councils planning department faced significant delays and resourcing challenges.The consultation process was extended following the introduction of the Health and Safety Executive as a statutory consultee for planning applications involving high-rise residential buildings. The scheme has now passed through Gateway 1 under the new Building Safety Act.AdvertisementBacked by client Rowdeal Investments, the 620m scheme will create a mix of one-bedroom studios and three-bedroom penthouse apartments on top of the inter-war block overlooking London Overgrounds Windrush line.On the front of the building, a light-coloured metal cladding distinguishes the new extension from the existing structure, while the rear features a set-back top floor and a two-story Cor-ten steel-clad faade.
