Alchemilla Architects Ltd is a RIBA Chartered Practice based in rural Somerset in the Blackdown Hills. Our work ranges from single houses and small housing estates to extensions and refurbishment projects. We see energy efficient architecture as integral to the built environment, and pride ourselves in providing a full service from inception to completion with our principal architect having been a certified Passivhaus Designer since 2011. Recently we have completed an EnerPhit refurbishment for a 1950s end terrace home and provided the Passivhaus assessment for 27 houses in Cornwall.
