Travelling Pavilion Brings Biobased and Circular Building Materials Together
BLOK, a travelling timber pavilion, brings together biobased materials, reused components and circular building systems in one structure. Presented at Dutch Design Week in Eindhoven from 17 October 2026, the project explores how these solutions can work together in construction.
The pavilion is an initiative of Blink and Janssen de Jong, both part of construction and development group JAJO, with REVOLVE as impact partner. It combines an exhibition, meeting space and testing ground, supported by workshops and events.
From Agricultural Residues to Building Products
Materials in BLOK include boards made from tomato stems, reed and seaweed. These applications demonstrate how agricultural and horticultural residues can become feedstocks for construction products, potentially connecting growers with new markets.
The pavilion combines these materials with timber construction, recycled plastic cladding, circular interior panels and reusable kitchen systems. Examples include reed-based interior boards from VanHier, seaweed interior panels from Seawood Materials and façade panels made from 100% recycled PVC by Pretty Plastic.
Other contributions include charred timber cladding from Zwarthout Shou Sugi Ban, biobased façade panels from NPSP and circular worktops from Sustonable. Solarix façade solar panels incorporate nesting boxes, while green roof pockets from Sam Groofing introduce planting into the building envelope.
Together, the products allow visitors to examine how material choices relate to the structure, interior, façade and energy systems of a building.
A Modular Structure Designed to Travel
House of Architects designed the pavilion, with Finch Buildings developing its cross-laminated timber (CLT) modules. Elementem built the structure, while Hal2 was responsible for the circular interior.
BLOK’s modular timber construction allows it to move between locations. Its first stop is Machinekamerplein at Strijp-S in Eindhoven, where it is scheduled to remain after Dutch Design Week for Nationale Klimaatweek and the GLOW light festival.
The pavilion will subsequently move to another location, potentially within a Blink development. Each stop is intended to introduce new visitors, project teams and ideas, allowing the pavilion to evolve through continued use.
Connecting Design, Materials and Production
The project began with a market challenge inviting companies to contribute low-carbon material solutions. Forty-four parties responded, and a selection of their materials and technologies now forms part of the pavilion.
Clients, developers, builders, designers and manufacturers collaborated from the outset. This approach makes BLOK a practical setting for exploring how different innovations interact when integrated early in the design process.
According to JAJO, lessons from the pavilion will inform future housing and development projects. The aim is to move beyond displaying individual products and build experience with their combined application, supporting wider adoption of biobased and circular construction.
