Building has begun on a controversial two-and-a-half-storey building on Cromer ridge that was dubbed by residents as the 'second Cromer lighthouse'.
Plans for the four-bedroom house, on land at the old zoo, were first submitted to North Norfolk District Council (NNDC) in October 2015 by Swallowtail Properties Ltd.
The design was condemned by opponents, with more than 40 official objections.
They said the building, which will feature a viewing tower and a sun lounge glazed on four sides, would infringe on their privacy and a number of trees would be lost.
At the time of the first planning submission to NNDC David Groves, spokesman for the objectors, said the house would "stick out like another lighthouse".
A decision was made on the plans in July 2016 where NNDC permitted the building, if the planners agreed to some conditions.
Conditions include telling the council of any exterior fittings such as lights and window, door and render colour, no trees being destroyed and if a tree is damaged, it must be replaced by the next planting season.
The building itself, on Howards Hill, will be set behind a 2m high wall and gates.
The developer, Pike Partnership, said: "The layout creates a flow of related internal and external spaces on five floors rising in half-storey connections.
"The line is essentially terraced down the hill, enclosing outside terraces to catch different times of the day, often related to the rise of the room within.
"The design is appropriate for the site in that it attempts to reflect the local landscape rather than vernacular character of the area.
"This room only enables distant views. No overlooking is possible to the south because of the screening provided by the roof of the sun terrace."
The land was run as a zoo by Olga Kerr from 1962. In 1984 a 400lb lioness named Lisa escaped from the zoo.
A 16-man squad of police officers rushed from Norwich to capture the lion, which was shot dead by police.
Building on the land, which has not been used since 1994, began on July 25, 2019 and is expected to be complete by October 10, 2020.
