The University of Exeter has applied for permission to build a three-storey extension to its Penryn campus.

The proposed building would extend the existing Environment and Sustainability Institute (ESI) providing additional laboratories, offices and collaboration space.

The ESI focuses on environmental research, with ongoing projects such as a major study on the impact of artificial light.

A design and access statement drafted by architects Stride Treglown says the proposed wing "will provide a world class science and research facility".

The statement goes on to explain that the extension would be thermally-efficient and built to high sustainability standards.

Architects say that it will have minimal visual impact from the road due to the high concentration of trees around the campus' boundary.

They say that only a limited amount of the building will be visible from the A39 approaching from Truro.

There will be no view of the new building when approaching from Falmouth, they say, and it will only become visible coming from Helston when approaching Treliever roundabout.

The application for outline planning permission has been submitted to Cornwall Council, who will seek advice from various consultees including Mabe Parish Council.

Cornwall Council's planning committee will make a decision on the application in due course.
