SE3D are a design-led team of Passivhaus consultants, architects and designers. As bePHit, the team also offers accredited Passivhaus certification services. We work collaboratively to help create healthy, human centred, high performance environments for our clients. We believe design is about people and the living and working environments we create for us and future generations to come. It is about how our environment impacts on us and how we impact on the environment – in other words ‘socio-ecological design’. As Passivhaus experts we are involved with the delivery of more than 500 Passivhaus dwellings, offices, schools, higher education, care and public pool and leisure facilities.
