Met(s)aRing - an adaptable modular framework for RMK small structures
Met(s)aRING is a research project by PAKK – Timber Architecture Research Center at the Estonian Academy of Arts, aimed at developing a circular and adaptable construction system for the small- and medium-scale visitor infrastructure of the State Forest Management Centre (RMK). The project addresses the fragmented and object-based nature of existing forest infrastructure by proposing a system-oriented approach grounded in life-cycle thinking and circular design principles.

Project executors: Algorithmic Wooden Architecture research group (EKA PAKK)
Researchers: dr Siim Tuksam, dr Sille Pihlak, Kaiko Kivi, dr Eero Tuhkanen (TalTech), Johan Kirsimägi; research assistants: Artur Raik, Madis Arp Keerd, Mano-Meelis Onni
Period: 18.08.2025–31.10.2026
Funding: State Forest Management Centre (RMK)
The first research phase focuses on establishing an analytical basis through the study of RMK’s existing structures, including benches, shelters, dry toilets, lean-tos, forest huts, and forest houses. Using document analysis, on-site observations, and model-based typological analysis, the research identifies recurring construction and material patterns and demonstrates that RMK infrastructure is largely composed of small- and medium-sized timber elements, which are well suited for modularisation and circular material strategies.
A central component of the study is the evaluation of industrial wood residues, particularly thermally modified timber and CLT production leftovers, as potential construction resources. The research explores how dimensionally variable residual materials can be integrated into adaptable systems through tolerant design logic rather than fixed, profile-specific solutions.
Construction systems for RMK visitor infrastructure based on wood industry production residues. Works by students of architecture and urban planning at the Estonian Academy of Arts (EKA). Supervisors: Kaiko Kivi, Siim Tuksam, Sille Pihlak.

Key Outcomes

  • Mapping of typologies and material-use patterns across RMK small-scale infrastructure.

  • Identification of favourable conditions for modular, demountable, and repairable timber systems.

  • Formulation of eight design principles addressing material use, adaptability, durability, transport constraints, and spatial identity.



Met(s)aRING establishes a strategic framework for the next development phases, in which the identified principles will be translated into concrete construction systems and prototype solutions for RMK infrastructure.
