1 Project name Admirals Hard Project summary FINALIST of the UK Passivhaus Awards Situated on the Stonehouse peninsula, by the banks of the River Tamar, Number 3 Admirals Hard was built in the 1950s and comprises a shop on the ground floor and WARMs office, originally a flat, on the first floor. The first floor is EnerPHit certified. The extensive retrofit works included external wall insulation, cavity wall fill, floor insulation (between the office and the shop), roof insulation at rafter level, high levels of air tightness and high-performance triple-glazed windows, as well as a self-balancing MVHR system.
