Heritage
Working on history takes more than force. It takes measure.
On listed and heritage buildings, ECOS SI.S.MA. acts as the executing contractor. No undocumented design or conservation qualifications are claimed: the role described is operational on site, respecting constraints and dialogue with designers and competent authorities.





Respect for fabric
Original fabric is considered before invasive action. Compatibility, sampling and operational caution guide site decisions.
Conservation and traceability
Where required, works are accompanied by photographic documentation and organisation that supports phase traceability.
Techniques and tools
Traditional techniques and contemporary tools may coexist, always in relation to the design and technical client instructions.
Protecting value
The operational aim is to help preserve the building’s historic and architectural value, without unauthorised alteration.
