The Challenge

Sustainability is full of trade-offs. Most teams get stuck in them.

Renovate or rebuild? Optimise embodied carbon or preserve future adaptability? Maximise today’s yield or invest in long-term value? Every decision opens three more questions. Without someone who understands the full picture - the physics, the financial logic, and the project reality - teams either stall or settle for checkbox sustainability.

For 17 years, I worked inside one of the Netherlands' leading architecture firms, leading international teams on projects ranging from modest renovations to developments worth hundreds of millions. I've seen sustainability from every angle, the ambitious visions, the messy realities, the moments where good intentions meet budget constraints.

That experience taught me something important: the hardest part of sustainability isn't knowing what to do. It's deciding what to do first, and navigating the dozens of trade-offs that follow. BREEAM score versus budget. Health versus energy. Ambition versus timeline.

I founded BLDG.Systems to sit where I'm most useful - at the intersection of strategy and execution, helping teams navigate these decisions with clarity. I bring the technical depth (architecture, building physics, certifications) and the strategic perspective (MBA in Innovation & Circular Economy, ESG investment) so that decisions work in drawings, in budgets, and in boardrooms.

Based in Amsterdam. Working across the EU with a focus on the Netherlands and Germany.

Approach

Not a checklist. A thinking partner —
wherever you are on your journey.

The kind of support you need depends on where you are and what the project demands. Sometimes you need a sounding board. Sometimes a facilitator. Sometimes someone to take the wheel.
