Gresford Architects Ltd

London

Gresford Architects are based in London and Oxford and seek to create buildings that are thoughtful, practical, sustainable and beautiful. We are interested in how spaces (and the buildings that create them) make us feel; how every decision that goes into creating a space – the materiality (surfaces, joints, planes, textures), the positioning of the windows and doors, of lighting and heating – must be carefully considered to allow the perfect marriage of the poetic and the practical. We have a fundamental belief in the importance of building in a sustainable manner, so that the buildings we create last for generations, are efficient in their use of materials and energy (in both construction and use) and are comfortable and pleasant places to be. We have a Certified Passivhaus Designer among our staff and will soon be recognised as a Certified Passivhaus Designer as a practice. We believe that the Passive House Planning Package (PHPP) is a tool that should be used to help design and inform the creation of new buildings from the outset, and encourage our clients to see the long term benefits of the early adoption of PHPP modelling on their projects. We also work with a wide range of experienced Passivhaus consultants, contractors and subcontractors, and can thus help our clients put together the right team to deliver their projects.

Mike Whitfield Construction Ltd

Hereford

Mike Whitfield Construction Ltd is based in South Herefordshire. Mike first worked on a carefully designed energy efficient building in 1996, and since then has been on a steadily improving journey. In 2005 we were main contractors on the conversion of 2 barns into offices for the sustainable architects Architype, a project which won the 2007 RIBA Sustainability Award. By the time PH became known in the UK, we were already using many of the principles, and in 2010 when we started our first project that had been designed using PHPP, it was a natural progression for us. Since then we have worked almost exclusively on retrofits, extensions and new builds to PH principles. Mike has spoken on construction methods and detailing at AECB and UK Passivhaus conferences.

Pen Y Coed Construction & Insulation

Welshpool

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: pycgroup.co.uk and warmcel.co.uk.
