Fundamental Principles
We use stone extracted from traditional Romanian quarries, hand-finished to restore the original texture and color of facades. Lime-based mortar ensures compatibility with the old structure and prevents cracks.
Durability and AuthenticityClay naturally regulates humidity, while reclaimed wood from demolitions is treated and reconditioned to be reintegrated into walls and beams. The result: a healthy indoor climate and an authentic rustic atmosphere.
Breathing WallsNatural hemp and wool fibers provide superior thermal insulation while being vapor-permeable. They are applied in thick brick or stone walls without blocking the building's natural breathability, enhancing comfort without ecological impact.
Natural Thermal ComfortThis guide exists to demonstrate that the authentic beauty of old buildings can be brought back to life exclusively through local natural materials, without invasive interventions and without compromising the original structure. The intended effect is a healthy living space with a balanced indoor climate, respecting both the urban architectural heritage and the environment.
Local natural stoneWe use stone from traditional Romanian quarries, hand-worked with chisel and hammer tools, to preserve the original texture and color of the facades. Lime-based mortar ensures chemical compatibility and allows slow drying, avoiding cracks and detachments.
Clay and reclaimed woodClay plasters regulate the natural humidity of rooms, and reclaimed beams from demolitions are treated against pests without toxic substances. This combination creates healthy walls that breathe and maintain a stable indoor climate.
Natural fiber insulationHemp and wool are applied in thick brick or stone walls, without blocking the building's natural breathability. Low thermal conductivity and high vapor permeability ensure optimal thermal comfort without compromising the historical integrity of the structure.
Urban heritage conservationEach intervention is designed to preserve the original character of the building: from the rustic finishes of the wood to the texture of the stone and the color of the mortar. The result is a facade that retains its authenticity but meets modern standards of safety and comfort.
Each team member brings unique expertise in the field of built heritage conservation, from applied geology to traditional carpentry.
Over 15 years of experience in local quarries from Măgura and Alun. She restored the facades of seven wooden churches and three 19th-century inns, using exclusively hydraulic lime mortar.
Master Carpenter and Wood RestorerSpecialized in recovering beams from demolitions and reconditioning them through chemical-free thermal treatment. He coordinated the restoration of the roof of a boyar house in Sibiu County.
Ecological Materials EngineerExpertise in applying hemp and wool insulation on thick brick walls. She conducted vapor permeability studies for 12 historic buildings in Brașov and Sighișoara.
Heritage ArchitectGraduate of the Faculty of Architecture in Bucharest, with a thesis on clay plasters in the Moldavia region. He designed minimally invasive interventions for three historic monuments in Argeș County.
From the first interventions on historic buildings to the certification of natural restoration methods, each stage has strengthened the principles of sustainable design.
The team intervened on a natural stone facade in the old center of Sibiu, using lime and clay-based mortar. The thermal behavior of the original wall was documented, and slow-drying protocols were established.
In collaboration with a local workshop, a 12 cm layer of hemp fibers was applied to a wall from 1920. Measurements showed a 34% reduction in heat loss without blocking the building's natural breathability.
Over 8 tons of oak beams were extracted, treated against pests, and reintegrated into a load-bearing structure. A technical guide on sorting and drying reclaimed wood was published.
After three years of monitoring relative humidity in a home in Brașov, it was confirmed that clay plaster maintains a stable indoor climate without requiring additional vapor barriers.
Over 60 restoration specialists participated in practical sessions on applying wool insulation and lime-based plasters. The resulting materials are now used in three urban conservation projects.
