01/Practice Develop · Design · Diagnose · Speak

One practice. One signature

Experience is causal, and everything here works that one claim. The practice used to run under four names. It now runs under this one: four lines of the same argument, develop, design, diagnose and speak, plus a small number of independent advisory mandates each year. Development keeps its own house and brand, Liven World; the rest signs under this name.

02/The lines Four lines · one claim
Line 01 · Development

Liven World

Co-Founder · Jan 2025 → present · Amsterdam

A home, for everyone.

Liven World develops next-generation residential environments designed around how people actually live, not around the spreadsheet they were sold from. Living infrastructure as a deliberate category, not a marketing claim.

It is the develop line of the practice with its own house and brand: a company, a team and a pipeline of its own. The thesis is shared; the signature there is Liven World’s.

Line 02 · Experience architecture

REDE

The experience-architecture practice of Jeroen Janssen · Oct 2025 → present

Built around lives, not just buildings.

REDE, Resident Experience Design, is where the design work happens: experience as system architecture, sitting between the spatial brief and the operating reality, where most projects under-deliver and few people credibly bridge.

It is the practice ground for how the four-system framework gets applied to specific developments. REDE keeps its own studio and name; the signature under the work is the same.

Line 03 · Diagnostic

XD

Launched May 2026 · 4–6 weeks · EN

An instrument that arrives before the building.

A pre-investment diagnostic for investors, BTR funds and family offices. The same four-system framework deployed as a fixed-scope read: to assess whether the systems around a place can carry the hold-period model the capital was committed to, before the model meets the resident.

Initial sessions scheduled with real estate investors in London. 2026 closed to new engagements; Q1 2027 opens in October.

Line 04 · Speaking

Speaking

Formerly User-Centered Real Estate · Oct 2025 → present

High-impact talks for the people writing the cheques.

Keynotes for developers, investors and public-sector leaders. The talks reframe lived experience as a financial variable, not a soft one, and every talk ends with a dated prediction that lands on the public record.

This line used to be a separate platform, User-Centered Real Estate. The name is now the talk; you book the person. Used at IC offsites, board sessions, public-sector convenings and industry stages.

03/Independent advisory A small number each year

Plus selective advisory engagements each year

Beyond the practice lines, I take a small number of independent advisory mandates with founders, developers, investors and boards working at the intersection of organisations, environments and capital.

Diagnostic

A 4–6 week pre-investment read. Assess whether the systems being built can carry the ambitions placed on them.

Delivered as XD

Advisory

Embedded across pre-development, design and pre-opening. Co-owns the lived-experience model with the team.
