Beyond the Balance Sheet
Alongside his work in climate and infrastructure, Julian is developing a personal collection of paintings, watches, and considered objects.
The collection follows the same instinct that informs his investment practice: look patiently, value substance over noise, and support work that becomes more meaningful with time. Each new acquisition is chosen for its craft, provenance, and capacity to open a different way of seeing.
- Paintings
- Works selected for material presence, perspective, and quiet tension.
- Watches
- Mechanical objects where precision, history, and design meet.
- Ongoing
- A growing collection shaped through conversations with artists, makers, and independent specialists.
