What Baukreisel does

Baukreisel is a Berlin-headquartered consultancy and research collective focused on circular construction, operating through a dual structure: Baukreisel e.V. (a registered non-profit association founded in 2022) and Baukreisel GbR (a commercial partnership established in 2023). The organisation delivers four interconnected offerings: architecture practice, full-cycle consulting, applied research, and teaching/summer schools. Its core technology centres on product-based reuse of building materials, combining selective deconstruction, digital documentation (IFC-based databases, 3D models, digital twins), physical testing (e.g., dew point tests for windows), and grey energy lifecycle assessment. Notable proprietary outputs include REMIX plan stones (concrete rubble cast into calcium silicate-compatible masonry units), REMODULE hybrid floor and stackable foundation systems (reclaimed concrete slabs with timber), and the window.matters upgrade methodology (up to 70% thermal improvement in existing windows).

Core offering

Baukreisel provides architectural and consulting services for circular construction, focused on material reuse, selective deconstruction, and grey energy analysis. The organization operates through a dual structure — Baukreisel e.V. (nonprofit association) and Baukreisel GbR (commercial partnership) — to deliver research, planning, and educational summer schools for public sector clients, housing cooperatives, and property developers.

Product overview

Baukreisel is a circular construction and architecture consultancy organized as a two-part structure: Baukreisel e.V. (a registered non-profit association for research, teaching, summer schools, and activism) and Baukreisel GbR (a partnership offering planning and consulting services). The portfolio spans four interconnected offerings: Architecture Practice (circular planning and design), Consulting (full-cycle reuse consulting from urban mine to installation), Research (product-based reuse research targeting high-CO₂ building components), and Teaching/Summer Schools (educational programs). Key named products and initiatives include concrete.matters (product-based concrete reuse research), window.matters (window upgrade strategies), Möbel aus Türen und Zargen (reclaimed door-to-furniture products), and the concrete.matters research report publication. All offerings share a common thread: treating existing buildings and materials as resources for circular, low-emission construction rather than waste.
