Developers have unveiled plans to install aluminium fins on the "Walkie-Talkie" to prevent the sun's rays reflecting so sharply.
Land Securities and Canary Wharf Group have submitted a planning application to the City of London for the brise soleil system.
The proposals say a series of horizontal aluminium fins will be installed across the southern side of the building
The 37-storey building in the City of London had started fires and caused damage to businesses across the road, and to cars parked nearby.
In September a temporary scaffold screen was put up at street level outside the building to prevent the sun's rays from reflecting and causing damage.
