From feasibility study through to handover of the keys. Every mandate has sharpened our processes and made our assessments more robust.

Institutional investors, fund managers and developers work with us – most of them not once, but across several mandates.

Across Germany and Europe – from Munich to Hamburg and Frankfurt through to Dortmund and Schönefeld. We work where your assets are.

The structure of a large firm. The swift decision-making of a small one. A single point of contact empowered to make decisions, with back-up support ready to step in when needed.

WE ARE SIRIOS. WE TAKE CARE.
Sound real estate decisions bring technical, commercial and strategic interests together. That is where Sirios comes in. Our interdisciplinary team creates transparency, makes clear recommendations and supports implementation - personally, independently and always focused on the client’s objectives.

Our Values
FOCUS
We begin every project with one question: What do you want to achieve? Everything follows from that: structure, processes and decisions. Your objective sets the course, not the project itself.
OWNERSHIP
Successful collaboration is built on trust. We build that trust through transparency, reliability and open communication as partners. This means our clients always know where their project stands and what they can rely on.
RESULTS
We see consulting as a long-term commitment. We take full responsibility for every project, from the first analysis through to successful completion. Our commitment extends beyond the outcome to the way we achieve it.
Our Principles
Think like an owner
We treat buildings, budgets and schedules as if they were our own. Not every measure is equally important. We prioritise based on risk, impact and cost-effectiveness.
Enable decisions
Our analyses go beyond a list of defects. We outline the available options, cost implications and dependencies, and make a clear recommendation.
Carry responsibility through to delivery
We coordinate everyone involved, keep costs, schedules and quality on track, and remain your point of contact until the agreed outcome is achieved.
What sets us apart
Institutional capability
Robust processes, well-founded analyses and structured project control form the basis of our work. Our clients receive the quality and reliability they expect from an institutional partner.
Entrepreneurial thinking
We always consider technical questions in the context of investment, use, risk, cash flow and asset value. This leads to commercially sound decisions rather than isolated technical solutions.
Personal accountability
Our clients work with dedicated contacts who take responsibility and are able to make decisions. Short routes and close involvement of the management team ensure speed, continuity and quality.
Interdisciplinary expertise
Our team combines experience from real estate, construction, building services, project management, ESG, energy and finance. This allows us to look at complex tasks as a whole and to reconcile differing interests.
Interdisciplinary expertise. Personal accountability.
Our success rests on the people behind Sirios Management Partners. Our interdisciplinary team combines expertise from real estate, construction and finance. With commitment, experience and a clear focus on your objectives, we stand alongside you as a dependable partner.
