Simon Knight Architects are an RIBA Chartered Practice established in the heart of historic St Albans.  We offer the full architectural service along with Passive House consultancy and are here to help guide clients through any project from start to finish.  We are passionate about high quality contemporary design and approach every project with a fresh perspective; seeking to fulfil the design brief, whilst being sensitive to the context and our environment.  Our designs are contemporary in nature but often inspired by the traditional vernacular forms and materials we find at our sites.  We work in a range of sectors and at different scales but treat every project with the same level of care and attention.
