Building a House Without Bricks is a Harvest Festival consisting of a public programme and exhibition hosted by damdam – a collective of collectives brought together by de Appel Curatorial Programme & Sandberg Instituut temporary master Lumbung Practice – which seeks to cultivate methods of collective organisation in times of crisis. The festival is formulated around three central questions: How to organise? How to distribute labour and resources? How to share what we produce?
The three day public programme at OT301 (12–14 June) is the first act, addressing these questions through practice. We are building the structure of our house through the often invisible infrastructures that support it, approaching the home not only as a fixed site but as something constructed relationally and continuously through practices of hosting. People themselves are the infrastructure of this house: shared time becomes a resource, care, attention, and mutual support become the materials through which continuity is sustained. Our host OT301 reflects these questions, with its history of squatting, legalisation and its current form as a collectively run cultural space.
The exhibition at de Appel (3 July – 14 August) is the second act, where we invite you into the house, turning to the physical and material structures inside. Acknowledging the limits of an exhibition, we focus on objects and their potential for resource re-distribution through transvestment (transferring resources from one value system to another). The objects are commissioned by the different collectives within damdam, who shared instructions to collaboratively build a house that reflects current needs in sustaining collective practice. With these objects, we build a house that can transvest resources into each collective’s local context, using a framework that balances production budget and fees with their needs.
Building a House Without Bricks seeks to create a house for our collectives through these infrastructures and objects, to continue practicing, gathering, and learning from each other. Through this festival, we celebrate the learnings we have gathered over the past two years together in the Lumbung Practice programme, and share them with our wider community.

Public Programme
11:00–12:00 madmad Kitchen - Lunch
OT301
DamDam(LP)
The madmad Kitchen is open every day for lunch and dinner at the Café Gilde. All food is vegan and cooked by the damdam community. The different meals are inspired by cuisine from the localities of the different damdam collectives, creating an experimental fusion kitchen.
12:00–15:00 Sewing for Collectives
OT301
DamDam(LP)
Sewing for Collectives is a two-session workshop taking place at the Ventilator Bar in which participants will collectively produce a large-scale textile fanzine. Using sewing, stencils, patches, buttons, and blings, we will transform fabric into a shared document inspired by the Care Pact/Work Ethic of the collective Biquini Wax EPS.
The Care Pact is a tool that Biquini Wax has built over its 15 years of existence. It is a living document about mutual care, awareness of privileges, fair distribution of work, and other agreements that have helped sustain collective well-being. The goal is to materialise and socialise this tool, and share it with the public. No previous sewing experience is required, just bring your hands and your willingness to work collectively.
12:00–17:00 Resource Map & Harvest Thesis
OT301
DamDam(LP)
This installation is situated at the Café Gilde and functions as both a resource map and a harvest of our Lumbung Practice theses. It offers an overview of the spatial, social, theoretical and practical knowledge, resourced within damdam and Sixpack, the collectives of collectives in Amsterdam and Jakarta. It helps us reflect on what we have, what we need, and how we can share with care.
12:00–17:00 Film Pot
OT301
DamDam(LP)
Film Pot takes place at the Ventilator Cinema and is a shared digital space where filmmakers contribute works into a common pool: a living archive built on trust, circulation, and collective use. It grows from the experience of translocal communities, the understanding that moving images can carry contexts across borders, and the belief that learning from each other's ways of seeing the world is in itself a form of being together.
This screening brings together a selection of films from this shared space: works made in the different localities where our ecosystems are grounded: Mexico, Palestine, Jakarta, Makassar, Jayapura, South Africa, Iran, Belgium, and The Netherlands. The contributions are presented as a looping, ongoing programme, and through a conversation with some of the filmmakers present. The films do not share a single theme, rather a shared condition: they travel and make place for encounters where physical presence was not possible.
12:00–17:00 Kiosk
OT301
DamDam(LP)
The kiosk is situated at the Ventilator Bar and is featuring various merch and publications from damdam’s constellation of collectives and Lumbung Kios, a decentralized network of independently operated kiosks currently hosted at Casco in Utrecht.
12:00–17:00 Print & Sewing Open Space
OT301
DamDam(LP)
The Print & Sewing Open Space is an ongoing, travelling project consisting of a modular and mobile accumulation of collectively owned — and borrowed — print, publishing, textile, and making resources, including a risograph machine, library shelves, book-making materials, sewing tools, and a DIY screenprinting table, among others.
Activated across Café Gilde and Ventilator Bar, the Print & Sewing Open Space functions as an open workspace, library, and kiosk where guests, collaborators, and friends — current and soon-to-be — can come together to print, sew, bind, mend, repair, publish, and experiment collectively. We are interested in sharing and exchanging DIY techniques of printing, binding, sewing, and publishing, making these tools and practices accessible to wider communities.
Rooted in the interrelation between self-publishing and textile practices as political tools to disseminate our own knowledges, the space will host workshops that merge both disciplines — from bookbinding with textiles and collective publishing to garment repair, sewing for collectives, and other hands-on experiments.
The Open Space also includes a library of publications contributed by members of damdam and its broader ecosystem. Workshops and activities will be announced via damdam’s Instagram.
17:00–18:00 madmad Kitchen - Dinner
OT301
DamDam(LP)
The madmad Kitchen is open every day for lunch and dinner at the Café Gilde. All food is vegan and cooked by the damdam community. The different meals are inspired by cuisine from the localities of the different damdam collectives, creating an experimental fusion kitchen.
