Architectural hotel motif

Hospitality real estate consulting where it matters today: in the existing portfolio.

We advise asset owners, asset managers and operators on modernisation, repositioning and operator transitions — strategically grounded, technically robust, with a clear focus on economic performance.

25+ years of experience
D-A-CH · SEE · Italy · Iberia

We work where hospitality and real estate intersect — and where decisions have a substantial impact on long-term value.

What we do

Developing existing assets, activating their substance.

Modernisation, repositioning, operator transitions — with a clear view of building reality, operational logic and economic levers.

Who we work with

Asset owners, asset managers, operators.

People who carry responsibility for property and operation, and need decision-making foundations that hold up.

How we think

Strategic, technical, international.

Conceptual depth, real estate precision and an international network — across D-A-CH, SEE, Italy and Iberia.

Services

Our consulting areas.

Four clusters covering the full lifecycle of a hospitality property — from existing assets through repositioning to new development.

Existing assets & modernisation

Securing value, activating substance, structuring investments.

Existing hotels today require decision-grade investment analyses — during ongoing operations, often under time pressure, at tenant or brand transitions. We provide the structured foundation: technically sound, financially clear, ready to implement. Entry is also possible as a desktop-only short review.

Repositioning. If the analysis shows that your asset cannot carry investment under the existing lease, the way forward runs through a restructuring Strategy & Operator Search

Market analysis & ESG

Decision foundations that withstand scrutiny.

Investment and valuation decisions need reliable numbers and a clear ESG pathway. We deliver both — methodically sound, market-realistic, fundable.

Project development & concept

Planning new hospitality concepts and making them viable.

For new builds, conversions and mixed-use projects, we accompany from the first idea to opening — keeping all three success dimensions in view: real estate, concept, operation.

Strategy & operator search

Finding the right operator — and securing a smart contract.

The choice of brand, operator and contract model shapes decades. We structure the selection process, create negotiation transparency, and guide through to signing.
