Plans to build a new 5G mast have been thrown out over fears it would block a popular city viewpoint.

Cornerstone, which builds 5G mobile internet infrastructure, had hoped to build the new mast on Mousehold Avenue close to Gertrude Road but Norwich City Council officials rejected the proposal saying it had the potential to obscure views of Norwich Cathedral, the cityscape and Mousehold Heath.

Plans would've seen a 65ft mast installed in the road along with six antennas, two radio equipment cabinets, a meter cabinet and a retaining brick wall.

Throwing the proposal out, planning officials said the mast would have caused "significant harm".

A statement in the decision notice read: "The proposed development would be sited in an area that is a strategic viewpoint and has protected long views.

"The height of the mast would be detrimental to the protected long views and appreciation of the historical landmarks.

"The presence of the pole in the skyline will detract from the views of the landmarks, therefore is considered to be causing significant harm."

Norwich City Council has not given any details as to whether Cornerstone will be able to appeal the decision.
