The 8th edition of Tallinn Architecture Biennale will question cost, value, and sustainability in architecture with the theme “How Much?”. TAB 2026 is curated by Kertu Johanna Jõeste, Ra Martin Puhkan, and Siim Tanel Tõnisson from Stuudio TÄNA (Estonia). They are working together with Mark Aleksander Fischer (Estonia) and Mira Samonig (Austria). TAB 2026 will run from September 9th – November 30th, 2026.
TAB 2026 examines the paradox of “cheapness” in architecture, encouraging architects to innovate within financial constraints while considering the broader, often hidden, costs of construction: social, ecological, and temporal. Instead of just looking at the price of materials or construction, TAB 2026 encourages architects to consider the long-term effects of their design choices. These choices can impact communities and the environment.
Through the main exhibition and a programme of competitions, a symposium and collaborations across academic and artistic fields, TAB 2026 tells various tales of how “cheap” is a critical, even generative mode of practice. Divorced from its narrow financial connotation, it challenges an architectural production. This production is submitted to a fundamental mechanism of capitalism. It’s about getting more out for less put in.
MAIN CURATORIAL EXHIBITION
The main curatorial exhibition presents nine projects by nine architectural practices—three local, three regional, and three international—responding to the binding question “How much?” through spatial practice. All contributors work from the same brief, establishing shared parameters. Including the wider cost of architecture across its lifespan, a common context of a slowly dissolving architectural structure inhabited by natural decomposers, within which the works must persist. As well a narrative format, using the tale as a medium capable of accommodating both speculative and built approaches. Instead of proposing a single programmatic answer, the exhibition highlights contrasts.
The concept shows how frugality at different scales, from large urban interventions to more intimate architectural works, can generate social, ecological, and design value over time.
“How Much?”
Building on this diversity of approaches, “How Much?” unfolds through five thematic interconnected sections. It looks at how working together can reduce costs while enhancing quality, how repetition and thoughtful efficiency can preserve integrity, and how simple, adaptable systems allow architecture to be both flexible and resilient.
Considering the power of compact, dense design to minimize waste, and celebrates the transformation of existing structures into sustainable spaces that honor their history. Together, these approaches show that constraints are not limitations but catalysts, sparking innovation, social responsibility, and ecological care in every project.
VISION COMPETITION
Alongside the main curatorial exhibition, TAB 2026 is launching its Vision Competition “From Void to Value” 2026.tab.ee/competitions/vision-competition, inviting architects, urbanists, and designers to propose innovative solutions for reimagining Tallinn’s UNESCO-listed Old Town. The competition focuses on the southern edge of the Old Town. This area is historically significant and was damaged during the 1944 bombings. Participants are challenged to propose strategies that balance heritage preservation with contemporary urban life demands. They must reactivate this urban void and reconnect it with the wider city.
Key to the competition is the rethinking of Harju Street, a major thoroughfare in the area. Proposals should explore how to transform public spaces, unused buildings, and vacant urban voids into vibrant and accessible places that meet the needs of both residents and tourists.
The complete Vision Competition brief is available at www.tab.ee. The deadline for submissions is April 27th, 2026, with winners announced by May 6th, 2026. Selected proposals will be exhibited at TAB 2026. The competition awards include:
first prize 4.499,99 €
second prize 2.499,99 €
third prize 1.499,99 €
five honourable mentions.
The competition will be evaluated by an international jury. Triin Talk is a Heritage and conservation specialist and a PhD candidate at the Estonian Academy of Arts. Keiti Lige serves as Visions Architect at the City of Tallinn. Klaske Havik is a Professor at Delft University of Technology. Siiri Vallner is an Architect and a partner at Kavakava. Siim Tanel Tõnisson is an Architect, TAB 2026 curator, and co-founder of Stuudio TÄNA.
OPEN CALL
TAB 2026 Open Call 2026.tab.ee/competitions/open-call/ invites architects, designers, artists, researchers, journalists, collectives, and other spatial practitioners to propose events and exhibitions within the biennale framework, responding in their own way to the central theme of “How Much?” and the broader questions of cost, value, and sustainability in architecture.
Proposals can include existing works or ongoing projects adaptable to the biennale context. TAB provides venues, visibility, and documentation, but production costs are self-funded. Submission must be sent by March 31st, 2026, as a one-page PDF (max 2.000 characters) accompanied by conceptual or reference images, sent to info@tab.ee with the subject line “Open Call”.

TALLINN ARCHITECTURE BIENNALE
Tallinn Architecture Biennale (TAB 2026) is an international architecture and urban planning festival with a diverse programme that promotes architectural culture. TAB encourages synergy between Estonian and foreign architects as well as between architects and the general public by way of creating contacts and exchanging ideas.
The core programme consists of five main elements: Curatorial Exhibition, Symposium, Tallinn Vision Competition, Installation Programme, and a Catalogue.
Tallinn Architecture Biennale TAB is organized by the Estonian Centre for Architecture. This year, TAB 2026 is titled “How much?”. As the curatorial team states, the biennale challenges us to rethink what affordability truly means in architecture today and will be curated by Stuudio TÄNA.
“Resources For a Future”
TAB 2024 “Resources For a Future” was curated by Anhelina L. Starkova with Daniel A. Walser and Jaan Kuusemets. TAB 2022 “Edible; Or, The Architecture of Metabolism” was curated by Lydia Kallipoliti and Areti Markopoulou in collaboration with local advisor Ivan Sergejev. TAB 2019 “Beauty Matters” was curated by Dr Yael Reisner.
The biennale focused on how beauty matters again, reflecting a cultural shift after nearly eighty years of dormancy when beauty was a tabooed and denigrated subject. TAB 2017 “bioTallinn”, curated by Claudia Pasquero (ecoLogicStudio), challenged the typical assumptions of what constitutes the boundaries between the natural and artificial realms.
TAB 2015 “Self-Driven City”, curated by Marten Kaevats, explored future cities with self-driven cars, whilst TAB 2013 “Recycling Socialism”, curated by Aet Ader, Kadri Klementi, Karin Tõugu, and Kaidi Õis, redefined the Soviet-era urban environment in Tallinn. Lastly, TAB 2011 “Landscape Urbanism” was curated by Villem Tomiste.
