A trumpet fanfare and a nursery rhyme rap marked the start of a groundbreaking ceremony at Loughton Manor First School last week.
Pupils and teachers celebrated as the development of their new teaching block officially began with a digger removing the first shovel-full of earth.
The £1.1 million project will provide the school with additional activity and learning space and allow a further 90 foundation pupils to be accepted over the next three years.
The new building will also accommodate the 30 existing nursery places.
Headteacher Lizzie Bancroft said: “It’s fantastic to see the construction of the building get underway after many months of design and planning.
“The new teaching block will be a welcome addition to the school and provide a much-needed resource for both pupils and teachers.”
