We have been advising clients for more than three decades, in most cases as part of a long-standing, trusting collaboration. Our success depends solely on the recognition we receive for our work from our clients and their trust in our integrity. The foundation of our success is staying true to our principles of independence, responsibility towards our clients and to society and a focus on our strengths.

  1. Independence from shareholders, institutions or interests
  2. Responsibility towards our clients and to society
  3. Focus on our strengths

We have been advising our clients for more than 30 years – independently, effectively and competently. Our greatest accolade is their trust in our integrity.


Architectural Solutions

We design technical and design solutions for the construction and renovation of buildings and property. THESAUROS offers an almost complete range of architectural and engineering services for buildings, interiors and engineering structures. We offer consulting services from the initial idea until project handover.

Project Solutions

The successful combination of construction and facility management is what makes our project planning stand out.

The task of project management is to control and manage a construction project in such a way that agreed deadlines and costs are met. The quality of the structure must ensure optimal use, with full consideration of the aesthetic, energy-related and ecological requirements of the client and legislators. With many years of experience in the field of Supplementary Defence, we fend off unwarranted contract addenda.

A valuable resource is topped off with the successful combination of corporate and facility management strategies. This is where the facility management aspect of Project Solutions comes into play, ensuring that companies' assets are maintained for the long term and are thus increased in the form of the building structure, technical building equipment and facilities. THESAUROS creates plans for technical and infrastructural building equipment for all tasks involved in conversions, new builds and expansions.

Urban Solutions

At THESAUROS project development is always an order-specific service. For the use of properties, we conduct studies for the purpose of settlement, resettlement and re-development. After consultation with municipalities and regional authorities, we draw up adapted urban land-use plans, master plans, land development plans, structure plans, project and infrastructure plans and landscape plans for private and public clients.


THESAUROS develops strategy & transformation and compliance processes for new corporate structures, conducts analyses of value creation potentials in portfolios, develops real estate concepts (including structured products) for wealth management clients and performs technical, legal and economic due diligence for real estate projects. We advise owners and tenants on the letting and re-letting of rental spaces. Real estate is marketed after the preparation of a bespoke, target-group-oriented strategy (purchase and sale), often within our own clientele group.
