Board of Examiners for Standardized Testing — Historic Specialty Certification, the credential Aspen requires to work on designated historic and landmark structures.
Aspen protects its history harder than almost anywhere in the country. Work on a designated historic property runs through the Historic Preservation Commission, and the City limits who is qualified to perform it. Holding an unlimited license and the historic specialty certification together is uncommon — it means one firm can carry a project from a full-scale build to the most delicate landmark restoration without handing off the parts that matter most.
Sensitive work on designated properties, executed to HPC standards and the City's review process.
High-finish custom homes and major renovations where precision, discretion, and schedule certainty are non-negotiable.
Bringing historic structures forward — additions and modernization that respect the original and satisfy review.
A builder's read on your project before and during construction — cost-certain planning and disciplined delivery.
Seamline is new to Aspen; its leadership is not new to demanding, high-stakes construction. Ryan Dumoulin led senior roles at prior firms on complex, code-intensive work — high-rise, healthcare, institutional, and large-scale residential — the kind of oversight Aspen's most sensitive projects call for. That experience is the foundation the Aspen credentials now sit on. See prior leadership experience →
