The research examines how the geometric, dimensional, and structural constraints of CLT offcuts can be integrated into architectural design logic. Through an interdisciplinary methodology combining architectural design research, material studies, parametric modeling, and structural analysis, the project develops a folded A-frame–based construction system in which material leftovers actively inform spatial, structural, and formal decisions.

A key outcome of the research is the development of a modular design-to-production system that enables the use of small, irregular CLT elements in prefabricated construction. The system was validated through architectural prototypes at three scales (approximately 20 m², 40 m², and 60 m²), demonstrating that 64–75% of the material volume can consist of reused CLT residues while maintaining structural performance and architectural coherence.

Key Research Findings

• Development of a folded A-frame small-building construction system optimised for CLT industrial leftovers.

• A parametric design-to-production workflow enabling the translation of complex geometries into manufacturable panel systems.

• An algorithmic structural calculation model allowing rapid assessment of stiffness, force flow, and joint behaviour in constructions composed of small elements.

• A taxonomy of CLT joint solutions, mapping structural forces and connection principles applicable to residue-based construction systems.

• Architectural typologies and design proposals demonstrating scalable applications of CLT offcuts in small residential and utility buildings.
