Empty properties have been refurbished to provide cheap housing.
Sanctuary Homes has renovated a four-bed family home in Fladgate Road, Leytonstone, and two flats in Greenleaf Road, Walthamstow.
It also plans to create a further 150 homes across the borough.
Janet Mussington, Sanctuary Homes’s head of development, said: "We hope this latest refurbishment is just the start of many new projects which will create much-needed homes as well as jobs and training opportunities in Waltham Forest."
The work was also part-funded by the Greater London Authority.
