Probably the most energy efficient barn conversion in Wales (or the UK).  Just completed. The layout is ideal for multi generation family use. Situated in rural North Pembrokeshire just south of the popular village of Mathry, between the  stunning cathedral city of St Davids and the ferry port of Fishguard.  10 miles from the Coun-ty Town of Haverfordwest with excellent shopping and amenities. Close to the outstanding Pembrokeshire Coast National Park and the famous Coastal Path with easy access to many sandy beaches and coves. There is an excellent golf course 1.5 miles away. The barns were constructed between the wars using cast insitu reinforced concrete. The walls are 150mm thick with columns cast in at approximately 2.5m centres to support the “A” frame timber roof trusses. The timber trusses and purlins were replaced with new structural timber and the roof recon- structed using Euromac 2 structural elements, which consist of galvanized “Z” purlins en-cased in 235mm insulation. These panels are tongue and grooved to form an airtight struc-ture with no cold bridging and replace traditional rafters. The roof covering is natural 7mm thick slate fixed using Nu-lok galvanized steel battens and stainless steel clips. This system has the advantage of allowing any slate to be replaced with-out damage to adjacent slates, and is designed to allow the slates to be replaced with solar PV cells at any time. The walls were clad externally with Marmorit external wall insulation 140mm thick and then rendered with Marmorit render which contains lime and fibres and is reinforced with a fibre glass reinforcing mesh and protected with a textured silicon render to ensure low mainte-nance. The external render is taken up over the ends of the roofing elements to ensure there is no air leakage at the eaves (tested air permeability 2.77 m³/(h.m²) without using any tape etc. The ground floor consists of reclaimed 1930’s hardwood blocks over 100mm thick dense self-leveling concrete, containing the under floor heating pipes, over 200mm thick insulation except in the sunroom area where the floor is 300mm thick over 200mm  insulation. This construction has formed a very large and dense thermal store inside the externally insu- lated building, which results in very even internal temperatures and prevents any sudden temperature changes. Two whole house ventilation and heat recovery units by Ventaxia have been fitted to provide fresh air. There 11 roof windows, four of which are remotely operated. A plant room has been provided to take the air source heat pump and the large thermal store for the heating and domestic hot water. The heating can be controlled remotely by any mo-bile device or computer. Ground mounted Solar Thermal panels have also been provided to heat the domestic hot water. Any excess heat generated by the panels is wasted to one of the two water wells at the property. These water stores also provide water for wc flushing and all other non- potable uses such as car washing and garden watering. The electrical lighting wiring has been designed and installed to ensure that it will use 100% LED low energy lighting, with multiple circuits to achieve variable lighting levels in each room. Fully fitted burglar alarms are fitted to the Barn and the out building. The doors and windows are all composite timber units allowing low maintenance exteriors while retaining natural wood interiors. The glazing is all high performance low-e and argon filled and has “self cleaning” coating. The south facing sunroom has been designed to capture solar gain during the winter and re-strict it in summer. There are 5 bathrooms (3 en suite) are provided and the layout is flexible to allow many dif- ferent uses. All internal partitions and ceilings are constructed using Fermacell gypsum fibreboard, which is far superior to plasterboard, it is impact resistant, fire resistant, and can take load bearing fixings. There is an additional modern timber building of 100m² which has been divided into 2 rooms and
