about us

 

Block722 is an Athens-based architecture studio, founded in 2009 by architect Sotiris Tsergas and interior designer Katja Margaritoglou.

 

The team combines Greek and Scandinavian heritage, as well as interdisciplinary experience, and creates work that feels confident, natural, and timeless. The studio undertakes a variety of work, from residential to commercial and hospitality, managing in-house all stages of architectural development, from concept design, through to construction and delivery.

 

Solutions always incorporate a focus on quality materials, a crafts-based approach and collaborations with local artisans and artists that interpret the Mediterranean spirit and traditions for the 21st century.

An architectural ethos that places a sense of balance at its heart is among this boutique, yet dynamic practice’s guiding principles. At the same time, Block722’s design solutions are strongly led by each project’s contextual needs and the client’s brief.

 

As a result, the studio has won several high-profile awards and has been featured widely in Greek and international media, such as Wallpaper*, ELLE Décor France, Cote Sud, RUM and Dezeen, AD magazine.
