The Founding Couple

An Indonesian-European bridge of culture, strategy and long-term vision.

Shared Philosophy

Build once. Build beautifully. Build to last.

Sherley is positioned as the founder-ambassador and cultural host of the House: a living bridge to Indonesian heritage, hospitality, taste, ritual and family story. Peter builds the strategic architecture behind the ventures, partnerships and media structures. Together they translate heritage into cultural gravity, and ambition into a house that can be recognised, trusted and carried over time.

Founder & Cultural Host

Indonesian Heritage, Hospitality & Cultural Relations

Sherley carries the cultural heart of House of Valenstone. Rooted in Indonesian heritage, Rejang family memory and a life between Indonesia and Europe, she brings hospitality, taste, ritual and ancestral story into the House. Her role is that of cultural host and bridge-builder: reading the room, opening doors with warmth and carrying relationships through lived cultural intelligence.

Founder & Strategic Architect

Strategy, Private Ventures & Business Architecture

Peter gives the House its structure: business architecture, strategic positioning, partnerships, growth logic and long-term enterprise value. His work is rooted in the discipline of turning ambition into blueprint, attention into position and opportunity into continuity. Within the House, he turns ideas into frameworks that can be trusted, repeated and carried over time.

Sherley's Heritage

Sherley's world is shaped by Indonesia: hospitality, ceremony, food, family memory, landscape and the human intelligence of welcome. Her story is rooted in Bengkulu and Rejang heritage, a foundation treated by the House with respect, discretion and archival humility.

Family memory connects this heritage to the historical world of Sumatra: Pangeran leadership, adat structures, Lebong's gold landscape and the old Dutch-Indonesian archive of trade, power and encounter. The House carries this as cultural depth and responsibility.

From Roots to Public Story

For House of Valenstone, this heritage informs the deeper cultural foundation of the work: the bridge between Indonesia and Europe, ancestral roots and modern hospitality, family memory and cinematic storytelling. Through First Class Indonesia, Taste of Ancestors and the hospitality vision behind Villa and Resort Valenstone, Sherley opens a world where culture is lived with warmth and dignity.

Peter's Architecture

Peter's work gives the House its strategic discipline. He translates creative and cultural ambition into ventures, partnerships and operating structures that can be repeated, protected and trusted beyond a single moment of attention.

A Shared Standard

Their shared standard is simple and demanding: build with taste, act with discretion, protect the relationship and think beyond the first generation. That is where the House becomes more than a brand. It becomes a living structure.
