Nigel Walter​ ArchAngel

Nigel Walter

Nigel is the founding director of Archangel, and a Specialist Conservation Architect. With 30 years’ experience of community-based architecture, he is central to the strategic direction of the practice. In 2018 he was made an RIBA Fellow in recognition of both his ’thought leadership’ and the positive social impact of his practice. 

‘I particularly love strong contemporary design in deeply historic places and remain involved in both practice and academic research; Archangel has developed to reflect that. This combination is mutually enriching, both leading to more considered design and keeping our research grounded, adding to the reach and impact of the practice.’

Nigel regularly writes, speaks and teaches on conservation. He is a member of the Association for Project Management (MAPM), a DCMS-nominated member of the Church Buildings Council, and an RIBA conservation accreditation assessor. He is also an active member of two ICOMOS International Scientific Committees: for Places of Religion and Ritual (PRERICO), and for Theory and Philosophy of Conservation and Restoration (Theophilos).

Away from the office he serves his local parish church as a Licensed Lay Minister.

Dirk ArchAngel

Dirk Visagie

Director

A longstanding member of the Archangel team, Dirk qualified as an architect in his native South Africa and has worked in the UK since 2005; he oversees the day-to-day running of the office.

Dirk works closely with clients, community groups, contractors, developers and consultants to help Archangel deliver projects in a collaborative manner. Part of his role is to help team members develop their skills and interests, and is currently busy integrating sustainability and modern methods of construction into our processes, to suit different project types and budgets.

‘I’m always trying to develop systems and explore how technology can provide best value for clients and the practice. I believe architects should make the design and delivery process more accessible and transparent to clients and project team members alike. The good news is that the tools are beginning to match the ambition – whether BIM technology, which Archangel has implemented from the outset, meetings via online platforms, or whatever other tools develop efficient ways of working for us and our clients.’

Dirk is a member of C3 Church Cambridge. He is also a scout leader (‘dib dib dib’) and enjoys almost any outdoor pursuits, though hasn’t been skydiving for a while.

Dani is a registered Architect, who trained and qualified in Barcelona, with experience in residential and heritage building. He is responsible for technical design and project delivery. He has been particularly involved with the detailed design of the works at Ridley Hall in Cambridge.

After qualifying, Dani participated in the ‘Architectural Innovation & Inverted Urbanism’ programme, researching new approaches to urban design to improve the resilience of settlements in the historic Terra Alta area of north-east Spain.

Outside of work, he enjoys exploring Cambridgeshire on foot, playing tennis or reading any book within reach.
