Construction has begun on the first phase of the new, £300m Mittal Children’s Medical Centre at Great Ormond Street Hospital for Children NHS Trust (GOSH), which is on target to become the UK’s ‘greenest’ medical building to date.

The scheme, designed by UK-based architectural practice Llewelyn Davies Yeang (LDY), is estimated to offset in excess of 20,000 tonnes of CO² annually - the equivalent to the typical yearly carbon footprint of around 2,000 people living in the UK. These figures are based on the scheme’s NEAT assessment, the health sector equivalent of BREEAM accreditation, in which the scheme has achieved an overall ‘Excellent’ Rating. This is a major step forward to achieving GOSH’s targets of a 120 per cent carbon reduction and 60+ per cent renewable energy contribution by 2016, when Phase 2 of the project is due to complete.
