New Life for
Existing Structures

Historic designation creates a framework, not a cage. While National Register listing and local landmark status impose review requirements on exterior changes, they rarely prevent thoughtful renovation. In many cases, designation unlocks significant financial incentives — including federal and state historic tax credits of 20–25% — that can substantially offset project costs. We navigate the review process with preservation officers regularly and design interventions that satisfy both the Secretary of the Interior's Standards and our clients' contemporary needs.

It depends on scope, but renovation often costs 10–30% less than equivalent new construction because the primary structure — foundation, walls, and roof — already exists. However, renovation comes with unpredictability: hidden conditions, legacy materials like asbestos, and non-standard framing can add costs. We mitigate this through thorough existing-conditions assessments and phased budgeting with contingencies typically set at 15–20%. When historic tax credits apply, the financial case for renovation becomes even stronger.

Structural surprises are common in renovation work, which is why we conduct invasive assessments early in the design phase — opening walls, testing foundations, and probing key connections before finalizing the design. Our structural engineering partners specialize in existing buildings and are accustomed to developing creative reinforcement solutions that minimize visual impact. We also build contingency budgets specifically for unforeseen conditions, so discovering a deteriorated beam or inadequate footing doesn't derail the project timeline or budget.

Most renovation projects take 6–18 months from initial assessment through completion, depending on scope and complexity. A straightforward residential renovation might complete in 6–9 months, while a full adaptive reuse of a commercial or historic structure — especially one requiring preservation review — typically runs 12–18 months. The design phase generally takes 3–5 months, with construction following. Projects involving historic tax credits add 4–8 weeks for the review and certification process.
