The ‘Nature and Wellbeing Centre’ aims to be the first centre of its kind in the country dedicated to connecting people and nature in ways that demonstrate positive benefits for both people and wildlife. It will also raise awareness about the importance of our natural environment for our own wellbeing and that of the planet.

Chief Executive for Kent Wildlife Trust, John Bennett, said: “This will be our flagship visitor centre and the gateway and natural companion to our remarkable Sevenoaks Reserve – a Site of Special Scientific Interest and the first in the UK to be developed from a sand and gravel quarry.

“Our foremost concern will be to maintain the wildlife value of this important and cherished site in the heart of Sevenoaks. This building will enhance and complement this special place.”

The Trust has also reported its most successful year yet in terms of visitor numbers to the site - estimated to be 75,000 people.

The initial phase of the competition will require teams to submit designs anonymously, in digital format. Four concept designs will then be shortlisted for further development at the second phase. The closing date for first stage entries is 5th December 2017.
