We have just started to deliver the new building, which is home to the university's School of Animal, Rural and Environmental Services.
It will provide a new focal point to the rural campus, near Southwell, with a reception and a prominent entrance.
The environment centre, adjoined by a linking entrance foyer, will provide world-class teaching, learning and research into major global challenges around the environment, ecology and conservation.
Exhibition and information space will showcase campus research, teaching and activities to staff, students and members of the public.
It will also include a cafe and dining area, a 200 seat lecture theatre with retractable seating, staff offices and state-of-the-art teaching and research rooms.
The structure will be a timber framed and set out over two storeys providing a total floor area of 2500m2.
Designed to be eco-friendly, it has sloping hipped roofs to complement the adjacent Brackenhurst Hall, and includes a mezzanine and roof garden and external spaces for staff and students.
The building is set to achieve BREEAM Excellent - meaning it will meet the highest ratings for sustainability.
