Tamias Group
Stewardship of built assets, from advice to execution
Tamias Group is an independent Luxembourg parent company based in Kehlen. It brings together four operating sectors around a single purpose: to design, structure, execute and finance the decisions that commit a built estate. This integration is not a commercial convenience. It answers a difficulty faced by family estates and institutional owners alike: a real estate decision is taken at the intersection of competences that the market usually keeps apart, and for which no single party answers as a whole.
The group operates in Luxembourg, Belgium and France, for families, private and institutional owners, and professional developers. Each sector holds its own licences, teams and accounts. The volume of mandates accepted is determined by the effective capacity of the teams to follow them, and by that criterion alone.
What we commit to
Three governance principles, enforceable and verifiable
Independence of remuneration
The group receives no retrocession, no introduction commission and no benefit from any third party on the decisions it recommends. Its remuneration derives exclusively from the mandate entrusted by the client or from the service performed. This rule applies across all sectors, including where a bank, a developer or a construction company is involved in the matter.
Separation of roles
Where one sector of the group acts on a matter structured by another, the involvement is formalised in a separate mandate and invoiced separately. The client has access at all times to the allocation of roles and fees. No intragroup service is provided on terms other than market terms.
Refusal of overcapacity
The group declines mandates it is not in a position to follow over time. An oversized co-ownership portfolio, a sales mandate accepted without conviction on price, or a project management assignment taken on without availability are risks for the client as much as for the group. This principle protects first those who have already placed their trust in us.
Our horizon
A built estate is assessed over twenty to thirty years
The value of a real estate asset cannot be read from a single financial year. It results from the technical condition of the property, the clarity of its ownership structure, the quality of its operation and the preparation of its transfer. Our recommendations therefore consistently favour maintenance over forced yield, a simple ownership structure over an arrangement that is costly to unwind, and an organised succession over one that is merely endured. Each of these choices carries a short term cost, which we accept and set out.
Our technical difference
Engineering competence sits inside the group
Fifteen years of managing construction operations and some 220,000 square metres delivered underpin the technical competence of the group. Our engineers are not consultants brought in at the end of the process: they examine the file before the decision is taken. That precedence is what allows us to establish the value of a property before it is marketed, the feasibility of a scheme before it is committed, and the real burden of a co-ownership before its mandate is taken on.
An integrated chain
Four sectors, engaged individually or in sequence
A matter may involve a single sector, or all four in the order in which they act: the estate strategy sets the objective, the engineers establish technical feasibility, the real estate sector executes the transaction or the development, and the finance sector arranges the funding.

Family Office
Estate strategy, structuring of ownership, asset arbitrage and preparation of succession. The sector acts ahead of the decision and coordinates all parties involved, internal and external.
Real Estate
Transaction, letting and property management, co-ownership management, property trading for own account and development. The sector holds the required business licences and operates in Luxembourg and Belgium.
Consulting Engineers
Delegated project ownership, structural engineering, project development and technical advice. The group carries out no construction works and holds no construction company, which is what secures the independence of its opinion.
Finance
Financing of real estate development operations through a dedicated debt vehicle, administered by an authorised manager external to the group and reserved for well-informed investors.
