  • • Rokos is relocating his residency from the United Kingdom to Greece while maintaining the multi-year renovation project, which involves over 500 workers and spans more than 200 rooms.

Summary
Chris Rokos, a prominent billionaire investor, is advancing with a £175 million restoration of Tottenham House near Marlborough in Wiltshire, marking what has been characterized as the most expensive private restoration undertaken in British history. The project involves the comprehensive renovation of a historic estate comprising over 200 rooms, supported by a workforce exceeding 500 personnel engaged across multiple phases of restoration work.

Despite shifting his tax residency to Greece, Rokos remains committed to the substantial capital investment in the Wiltshire property. This decision underscores the distinction between personal residency for tax purposes and asset ownership strategy—a common approach among ultra-high-net-worth individuals who optimize domicile status while maintaining significant holdings in other jurisdictions.

The Tottenham House project exemplifies the premium placed on heritage property restoration by institutional wealth holders and family offices. At £175 million, the investment reflects both the historical significance of the estate and the scale of infrastructure, architectural, and systems modernization required to restore a multi-hundred-room property to contemporary standards while preserving historical integrity. The scale of the workforce and timeline suggest a multi-year commitment extending well beyond Rokos's anticipated residency change.

This transaction represents a notable data point in the UK luxury real estate and heritage property markets, demonstrating continued appetite for transformational restoration projects despite broader economic and regulatory considerations affecting wealth management structures in the region.
