What we do
New buildBarn conversionsFull house retrofits




By ‘high performance’, we mean homes that are designed and specified to meet the rigorous performance criteria of the Passivhaus Building Standard, and which deliver high standards of comfort and health for their inhabitants, whilst also being good for the environment. If you are unfamiliar with Passivhaus, or unclear regarding the benefits, we invite you to download our Passivhaus Infosheet which on a single page describes the key principles, features, advantages, and benefits.




By ‘self build’, we mean that we work with people who want to commission the design and construction of their own home, and who are therefore inherently interested and invested in creating homes that are both beautiful and functional. We know that while many people would like to build their own home, they never take that first step, simply because they don’t know where to start. It is for this reason that we created the Self Build Starter Pack, with a selection of simple worksheets to help aspiring self builders get started with their self build journey.




As highlighted by the name of our practice, we are specialists in homes. protaHOMES was founded to help people create homes that delight and enhance their quality of life. Please feel free to check out a selection of some of our projects by clicking the button below.
