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.

About

17 years
of detail.

One studio in Thessaloniki and Attiki, 15 specialists, and a single conviction — that detail is what turns a building into an asset.

The studio & the journey

Theodoros Thomaidis · Founder

The founder

Detail, as
a philosophy.

M.Architect Theodoros Thomaidis founded Detail Architects in Thessaloniki in 2008. Since 2012 the practice operates a second office in Attiki, with a team of 15 specialists across architecture, interior design and property management.

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

"In Greece, hospitality is a generosity of the spirit."
