Planning approval ยท London Borough of Barnet
Planning permission was granted in 2019 for part single- and part two-storey front, side and rear extensions, following demolition of the existing garage and creation of a basement level. A separate lawful-development certificate covered the hip-to-gable roof enlargement, rear dormer with Juliette balcony and three front-facing rooflights.
Planning reference: 18/7533/HSE ยท Lawful-development reference: 18/4693/192
