Dr Nikolaos Karydis

Nikolaos is is a practicing architect and Senior Lecturer in Architecture at the University of Kent specialising in the fields of Architectural History, Urban Design and Conservation. He studied Architecture at the National Technical University of Athens, and Building Conservation at the University of Bath. The doctoral thesis he carried out in Bath from 2006 to 2009 was distinguished with the 2010 R.I.B.A. President’s Commendation and resulted in his book on Early Byzantine vaulted construction. From 2010 to 2012, Karydis was Assistant Professor of Architecture in the Rome Studies Program of the University of Notre Dame. In 2012, he moved to the University of Kent where he founded and directs the MSc Programme in Architectural Conservation. Following his publications on Vernacular construction and Byzantine Architecture, Karydis is now investigating the urban development of Early Modern Rome and has recently been awarded a Balsdon Fellowship at the British School of Rome (2019). 


Sara Yabsley

Sara collaborates with Apollodorus Architecture as a practice consultant. She is founder and director of Yabsley Stevens Architects since 1998. 
Sara studied architecture at the University of Bath. After receiving her professional qualifications in 1990, she worked for Nicholas Grimshaw & Partners on Waterloo International Station, for Wilkinson Eyre Architects on the Crossrail Redevelopment of Liverpool Street Station, and with Alison Brooks Architects on award-winning projects.


Gerasimos Mataragas

Gerasimos collaborates with Apollodorus Architecture on masterplanning projects. He undertook his undergraduate and postgraduate studies in architecture at the University of Bath. His dissertation on Filarete’s Treatise on Architecture investigated the theme of the ideal city during the Renaissance, while his thesis project explored the re-use of historical elements in civic buildings through the process of translation. Gerasimos currently works in Greece, in the fields of architecture and urbanism, both  private commissions and competitions. 


Apollodorus of Damascus

Okay, this long-dead architect is not actually a friend or collaborator, and we don’t conduct seances to get in contact with his spirit. But he is one of our greatest inspirations. Apollodorus designed Trajan’s Forum and Trajan’s Baths in Rome, the staggering bridge over the Danube (with its 19 spans of 150 ft or 44m) that is represented on Trajan’s Column, which was almost certainly designed by Apollodorus as part of the Forum. 

Apollodorus – who may or not have been from Damascus (this is only mentioned in one source) was probably also responsible for the Pantheon, the favourite buildings of so many architects past and present. The building of the project, however, evidently ran into problems over the supply of the sixteen 50 ft, 100 tonne, monoliths from two quarries in Egypt that were intended for the portico. The image here shows a reconstruction of what Apollodorus had in mind – so in that sense I have 'collaborated' with Apollodorus (along with my old friends David Hemsoll and Paul Davies).


We cannot really know what happened, but the actual building features 40 footers, which may have been diverted from another project by the emperor Hadrian, who had succeeded Trajan. Naturally Apollodorus wasn’t keen and a big argument ensued, as we can intuit from a passage written around 100 years later by Dio Cassius (69.4) which told how an incensed Hadrian, jealous too of Apollodorus’s talents, had him put to death. This warns of us of the dangers of being too objectionable to our patrons...
