Callidus Design has been appointed by Natural Retreats to provide the services design for a development of 20 luxury holiday lodges at the Pystill Farm site on the Llyn Peninsula. The proposed development will be served by a Biomass Boiler and associated District heating system to provide Heating and Domestic Hot Water to each lodge. The installation will also incorporate Photovoltaic (PV) tiles on the roofs of the lodges to generate a significant portion of the electrical energy needs of the development.
