Penoyre & Prasad - one of the UK's leading architectural practices - are renowned for buildings that are centered on people's experience, and are green as well as visually striking. Transformations provides a comprehensive overview, in their own words, of the practice's designs and the thinking behind them. An essay by Thomas Muirhead gives an architectural assessment and is followed by eight essays by Sunand Prasad. Interspersed with detailed project descriptions, they offer a unique and personal insight into Penoyre & Prasad's 19 years of work.
