As a former colleague I was deeply saddened to hear of the death of Anne Hemming. She was a thoughtful and stimulating public servant of the highest integrity.

As a memorial to her, and bearing in mind your recent campaign, I ask that all concerned – government, the industry, academics, regulators – unite to complete the development of an improved building control system within the next 12 months. It should be sustainable, encourage quality, combat climate change, be enforceable and above all be comprehensible and predictable.
