Tewke's founder, Piers Daniell was recently featured on Channel 4's Grand Designs, as the builder of the first castle in Britain for over a century, which has been a living testbed for Tap. It’s a truly monumental build.  Piers is installing 54 Tap switches throughout the site. Despite the size of the development, Piers is aiming for a building that is going to be one of the most highly performing, environmentally friendly homes in the country, with passive levels of air tightness, high levels of thermal insulation, batteries, solar tiles, vertical wind turbine, advance water harvesting, state change water heaters and triple glazed solar glass throughout. This will make the home low cost to run but also minimise impact and demonstrate to all homeowners and builders what is possible. Tap switches will sit right at the heart of that set up.
