The glass-fronted building, opened on 12 July 2012, links the former Victorian coach house and stables and allows visitors to enjoy views of the Forest from the external timber walkway as royalty once did from the adjacent Queen Elizabeth's Hunting Lodge.
Head of Epping Forest visitor services Tony Fenwick said:
"The feedback has been overwhelmingly positive with most mentioning the friendly and informative staff, enjoyable exhibition and of course the spectacular views as being their favourite experiences.
"We look forward to seeing even more visitors enjoy this fantastic building over the coming years."
Epping Forest Superintendent Paul Thompson said the City of London Corporation chose Chingford because it has a bus terminal and has a mainline train link to Liverpool Street. It was important to reflect "the Victorian model" of public accessibility, he said.
The building is open daily except Christmas Day and was awarded a gold accreditation by the Green Tourism Business Scheme for its environmental design and visitor experience. Green features include sensor-taps and toilets which flush using harvested rainwater.
The building is fully accessible, features a learning and community room, shop and community room.
