We are engineers, not demolition contractors.
Founded in Dresden in 2025 — out of the conviction that a building that has stood for 120 years knows more about good construction than any of today’s standards.
Four principles behind every project.
Fabric before demolition
We first examine what can be preserved — demolition is the last option, not the first.
Permit certainty from day one
Heritage protection and the building authority are part of our thinking from the start, not only at submission.
One point of contact, every trade
Structure, energy, heritage protection and site management come together with one person — not across five interfaces.
Transparency on costs & risks
Risks in the existing building are named before they turn into additional claims — even when that is uncomfortable.
Two disciplines, one point of contact.
