This project reimagines building as an evolving system, where the house grows, adapts, and reorganizes over time. Unlike fixed, institutional models, domestic space is understood as open-ended—shaped by use, climate, and change. Build in stages. Build as needed. The house begins with a core—hearth, kitchen, wet areas—a complete minimum dwelling. From this core, it grows.
A ‘Construction Manual’ replaces the traditional blueprint. Construction becomes accessible, incremental, shared. The construction manual allows inhabitants to participate directly in the making of their homes. It removes the need to build everything at once, enabling gradual expansion in response to shifting lives—growing families, shared households, changing routines.
One material, many roles. Hempcrete consolidates structure, insulation, and enclosure into a single, breathable mass. The house is not layered—it is thickened. It is not sealed—it breathes. ‘ Hempcrete Layers of domesticity’ emerge through gradients of temperature, light, and occupation. Construction and inhabitation become one continuous act. The house is never complete. It evolves with those who build and inhabit it.
After Concrete
Steel and concrete are major sources of CO₂ emissions, and recent building losses reveal how little of these materials can be reclaimed, often ending as waste.
Addressing this challenge, this thesis investigates the potential of carbon-negative assemblies as a strategy for more sustainable built environments. It focuses on hempcrete, a carbon-sequestering material, proposing new models of rural domesticity. The research examines how such materials can inform conceptual design, construction methods, and assembly strategies.
Remnants of Construction
Steel / Concrete / Glas
Hempcrete Wall Fabrication
A hemp hurd–lime mixture is compacted within the wall panel around wood structural members. At the end of its life, the hempcrete can be returned to the soil as fertilizer, where it gradually decomposes.
