Pedro Bravo Navarro

Pen Y Coed Construction & Insulation (PYC)


From Passive House design and construction to high quality joinery finishes, we pride ourselves in creating beautiful and sustainable buildings. With over 25 years' experience, we prioritise a 'Fabric First' approach that starts at the design stage, using materials and products that maximise the performance and energy efficiency of the building. Our timber frame houses begin life in our factory in Wales as fully engineered, insulated and air-tight closed panels. The panelised units are then transported to site where a weather protected structure can be assembled in a few days. The materials in our build systems are predominantly timber based and procured locally where possible. By using Warmcel cellulose fibre insulation along with timber and woodfibre lining boards, timber I-beams, timber windows, and timber cladding, carbon is locked-in to create a sustainable building that is healthy, comfortable and enjoyable to live in. Warmcel has also been awarded a Nature Plus Certificate. Full technical information is available on our website: and

Along with other local authorities, Perth and Kinross Council have a duty to commit to reducing energy use and carbon emissions by ensuring that new builds are as energy efficient as possible, and that our existing building stock is optimised in terms of energy use. We believe the Passivhaus standard is a key industry standard for delivering high quality, low energy buildings. We currently have several Passivhaus projects in different stages of development, including new primary and secondary schools. Our staff have been undergoing various levels of Passivhaus training, with some members now trained as Passivhaus Designers. We look forward to further developing our knowledge and experience of Passivhaus and EnerPHit as our projects begin to come to fruition.
