Hallam Environmental Learning Centre. Sector: Education. Value: £390k. Client: Notre Dame High School (Sheffield West) City Learning Centre. Notre Dame School sits in beautiful, extensive grounds which contain many different wildlife habitats. The school wanted to exploit this tremendous educational resource, so commissioned the ELC as a remote classroom. Careful consideration was given to its impact and connection with the external environment. The building has an envelope heavily insulated with sheepswool and woodfibre boards on a hybrid oak/steel frame, roofed with cedar shingles and finished in lime-based render. Solar thermal panels provide hot water for the changing rooms. The classroom is light and airy and has extensive IT facilities.
