In 2012 Ben Adam-Smith founded House Planning Help to collect and share all the information he started to learn on the way to designing and building his own home. His mission is to encourage people towards the "...houses we should be building in the 21st Century."

When Prof. Dr. Hartwig Künzel was studying Chemical Engineering, his father was a scientist at the Fraunhofer Institute. Hartwig followed in his father's footsteps after becoming interested in the preservation of heritage buildings. He soon discovered that he could apply his engineering training to diagnosing the moisture problems that occurred after buildings were insulated.
