Rainham is a terrific example of how smart thinking, in design and build, can be achieved at reasonable cost and meet the needs of those who need it most. By adopting Passivhaus principles we were able to bring a level of innovation to the project that not only ensured high quality, but the highest standards of sustainability along with affordability – a triumvirate seldom achieved”
