BlocK722 architects BlocK722 is an Athens based architecture and interior practice.

“To rise all senses through authentic and timeless experiences”

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, fr

om residential to commercial and hospitality, managing in-house all stages of architectural develop-ment, 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.

Sun Salutation Room

Block722’s “Architects of the Year” installation is a spatial manifesto that blends architecture, interior design, art, and storytelling.

Inspired by Mediterranean spirit and Scandinavian clarity, it explores contrast as harmony and simplicity as depth.

The experience begins with the primal elements - earth, air, light.

As visitors move through the space, they transition from intensity to calm, from exposure to protection, from shadow to light.

The installation becomes a ritual of reconnection with place, material, memory, and self - an atmosphere activated through all senses.

At the heart of the space, a rock acts as a vessel of memory, engraved with three Block722 projects that trace a path of internal journey and evolution.

The “Greeting to the Sun” invites visitors to pause, observe, and remember: every project begins with a lived experience - and ultimately returns to the light.

Amid the wild beauty of eastern Crete, O Lofos unfolds on the foothills of Thrypti mountain a discreet modern home shaped by the island’s natural landscape and local craftsmanship.

Built with stone, wood, and the touch of Cretan artisans, the residence blends Mediterranean authenticity with Scandinavian simplicity, creating a serene retreat rooted in place and material.

At Block722, we believe that true wellness begins with space itself.
At Olea Spa, we designed an environment of understated luxury, calm, tactile, and deeply connected to nature.

Through earthy textures, filtered light, and sculpted materials, the spa becomes more than a retreat.
It is a holistic experience, where architecture and atmosphere restore both body and mind.

For Block722, water is an infinite canvas.

It frames the landscape, dissolves edges, and creates moments of weightless calm.

From still reflections to flowing horizons, it becomes the silent partner of our architecture.

A fluid dialogue between nature, design, and the human spirit.

At Block722, we envisioned Eco Villa at Gundari Resort, Folegandros as a dialogue between land, architecture, and memory.

Perched on the cliffs, the villa merges with the island’s raw beauty through local stone, plaster, wood, willow, and olive trees. We designed sheltered courtyards and terraces that invite both gathering and solitude, always in harmony with the natural environment.

Our goal was to reflect the unhurried rhythm of Folegandros—to create a retreat that feels timeless, serene, and deeply rooted in place.
