About Us

Evissa team is focused on achieving the highest levels of indoor air quality and energy efficiency through Passive House Design and by using Evissa Structural Insulated Panels and Modular Technology. Evissa was created as a partnership between Elena Cazacu – Architect (ARBV) & Passive House Designer and Gareth Owens – Domestic & Commercial Builder (DBU / CBL) and Passive House Certified. Both directors are trained overseas and have a wealth of diverse experience gained from their involvement in different scale projects across Romania, Europe, the UK and Australia. Before creating Evissa, Elena was working as a sole practitioner architect and Gareth was running his own construction company as a builder. When applying their overseas working knowledge locally, in both Architectural Design Practices and Construction Industry they discovered a great opportunity to bundle Passive House Design with Modular Technology and created Evissa SIPs as a construction material that would streamline the traditional methods of building.
