Roof Overclad Gets Go Ahead on Norwich Railway Depot

THE 7,727m² metal roof of Norwich railway station’s Crown Point train depot will receive a full roof overclad after planning approval was granted this week.

The application submitted to Norwich City Council in March is for the Norwich train engine shed, known as Crown Point Depot, roof to be overclad using an insulated metal panel system.

The plans were lodged after the building had been suffering from “water ingress issues for years due to insufficient capacity” and other problems with the roof’s drainage system.

The work is permitted under The Great Eastern Railway Act 1875 but the need to minimise damage to the surrounding vicinity meant plans were submitted to the city council.

The Council confirmed on Tuesday 23 April that planning was granted to allow the project to progress.

Roof Overclad

The new roof will overclad the existing pitched profiled metal panels raising the overall height by around 30cm. The additional height is said to result in “minimal visual impact”.

The plans include replacing guttering with a new aluminium gutter drainage system.

New rooflights are incorporated and additional access hatches and walkways to improve connectivity of some maintenance routes, as well as lightening protection.

A single ply EPDM roof and PIR insulation will replace existing felt on the flat roofs of three ancillary buildings and a mansafe fall arrest system will be installed on those roofs.

The Crown Point Depot houses 58 Greater Anglia trains where they are stored and maintained. In 2018, the depot underwent a £40m large-scale expansion to increase capacity.
