The Founder
“In Greece, hospitality is a generosity of the spirit.
Theodoros Thomaidis — M.Architect, Founder

He founded Detail Architects in Thessaloniki in 2008, with a second office in Attiki since 2012. Over 17 years the practice has grown to a 15-specialist team delivering architecture, interior design and property management across Greece.

The Investment Architecture philosophy — treating every project as a financial asset — emerged from years of watching owners under-realise the potential of their properties. Detail Architects changed that.
