Zac Monro takes on a tiny 70s ex-council house in south London. His radical solution is to knock the house down and start again with an open plan design. In Jesmond, Newcastle, Abid and Sameena Nawaz hire Zac to update their 1940s home, including building a garden office and new kitchen. Zac and engineer Monty Ravenscroft transform the garden shed with mirrors and LED lighting, while gardener Rosie Bines plants a white garden to be enjoyed both day and night.
