OPEN HOUSE ISTANBUL
ISTANBUL, TURKIYE
7-10 MAY

For the first time in Türkiye, the Open House festival makes its debut in Istanbul, inviting the public to explore the city’s layered urban fabric and rich cultural life.
Taking place across Beyoğlu and Büyükada, the largest of the Princes’ Islands, Open House Istanbul opens the doors to nearly 40 buildings —from private apartments and historic mansions to universities, art studios, architecture offices, and hotels—offering a rare glimpse into spaces that are usually closed to the public. For four days, Istanbul opens itself, inviting you to experience the city from hills to shores.

This year's edition of Open House Basel includes 115 buildings across Basel and neighbouring areas in France and Germany. Highlights include contemporary projects such as the Roche office tower Bau 2, Biozentrum, and Codeck, a former office building transformed into housing and music spaces. Visitors can also explore innovative developments like LYSP8 in Lysbüchel, built using sustainable “Design for Disassembly” principles.
Open House Basel PLUS+ expands the programme with talks, tours, and exhibitions, while Open House KIDS offers a playful way for families to discover architecture.

OPEN HOUSE LISBOA
LISBON, PORTUGAL
9-10 MAY

Open House Lisboa returns for its fifteenth edition with a fresh perspective on the city, this time through the lens of food. From kitchens and markets to factories, community gardens, and private homes, the festival opens doors to spaces that shape everyday life but are rarely seen. Highlights include behind the scenes access to locations such as the Pastéis de Belém factory, the historic Mercado da Ribeira, and Cervejaria Trindade. There are also curated urban walks tracing food systems across the city, hands on activities for families, and a diverse Plus programme featuring exhibitions, workshops, and performances.

OPEN HOUSE ROSARIO
ROSARIO, ARGENTINA
9-10 MAY

In its ninth edition, Open House Rosario expands its focus beyond the city centre, broadening the map to include new districts and peripheral areas. While central Rosario remains rich in architectural growth and heritage landmarks, this year’s programme highlights the diversity of the wider city, showcasing quality architecture across a broader urban landscape, building on previous editions that introduced locations such as Funes and Fisherton.
