Works are planned at a school after "significant decay" was found in one of its buildings. 

Storrington Primary School will likely get a new temporary classroom after problems were found in the timber walls of some of its classrooms. 

After a structural inspection by engineering company Archibald Shaw, chartered engineer James Teuten said "significant decay" was found in the timber floor joists around the edge of the building.

"The timber decay has sufficiently compromised the building’s structure, such that it appears beyond economic repair," Mr Teuten said in a report.

"The building should be replaced in its entirety during the upcoming summer holiday."

West Sussex County Council has submitted plans to build a new temporary classroom building and install fencing at the primary school, where 381 children are on the roll.

The council is seeking permission for the classroom at the Spierbridge Road school to be used for up to two years.

In a report for the council, specialists DHA Planning said: "Overall, the design is considered in keeping with the existing character of the site and is appropriate for a temporary use.

"The development is water neutral and there are no traffic or amenity issues that outweigh the significant need for the proposed development. 

"As such, this application should be given favourable consideration and we request that planning permission is granted for the proposed development at the earliest opportunity."
