Where are you currently at?
Corporate Real Estate · Investing in a new working environment
The spaces should be attractive, healthy, and future-proof.
→ Which measures really improve user experience and employer attractiveness?
New Work Project Management · Planning a new location
Sustainability, health, and digitalization should be part of the planning from the very beginning.
→ How do we integrate this in terms of schedule, organization, and budget – and what makes this location special?
Occupier · The space needs to be certified
Often, there is a corporate mandate that applies to all locations.
→ Which standard fits your goals and budget?
Workplace + Tenant Representation · Employees expect functional work environments
There is a gap between expectations and reality that no one can account for.
→ How do we turn subjective assessment into measurable quality – and how do we ensure everyone is treated equally in the process?

Are you planning a space and want to know what really works?
We start with the people who will be working there.
What we work with
Workspace + user assessments
Leasing, renting, redesigning, or reorganizing office locations. Surveys, user analyses, and recommendations for action regarding safety, comfort, performance, and employee retention.
Measurements
Indoor air quality, lighting, acoustics, and comfort in existing or new rental spaces. Measurement report including key performance indicators, deviation analysis, and optimization potential.
WELL Strategy
When health and user experience become the standard. Strategy for comfort, HR topics, catering, and medical services, including goal definition, an overview of measures, and optional WELL certification.
LEED ID+C + DGNB for Interiors
Interior and tenant fit-outs with certification goals, including multi-site projects. We handle certification strategy, moderation, coordination of all stakeholders, and documentation through to the final issuance of the certificate.
Smart building + connectivity analysis
Planning future-proof spaces, leasing, or renovation. Assessment of digital infrastructure with recommendations for construction, software, and provider contracts.
Energy Audits
If your company is required to conduct energy audits across multiple locations. Audit report including measures, key performance indicators, and recommendations for action.
Simulations
Validation of planning decisions regarding energy, comfort, daylight, and microclimate. Simulation report including scenarios, key performance indicators, and optimization recommendations.
WELL Performance Testing
Frequently Asked Questions
How is the budget allocated between interior fit-out, FF&E, and operator-related items?
We disclose the costs for construction and building services (cost groups 300 and 400) following our analysis and in collaboration with your planners. Regarding furniture and equipment, we review your supplier contracts, as we believe new furniture, energy-efficient lighting, and technology are necessary regardless.
Which colleagues from HR and Facility Management should we involve?
HR plays a key role in planning and certification, with the FM team providing support. We enjoy working directly with both and facilitating their coordination.
Can you prepare the results for marketing and internal communication purposes?
Yes. We will show you samples from previous projects and tailor them to your specific needs.
What specific added value does the certification offer us?
Certification makes the quality of your work environment visible and transparent. It supports employer branding and employee retention, while providing valuable insights for leasing or repositioning rental spaces to prevent vacancies.
How much internal effort is required from us during the certification process?
If you limit this to construction-related topics, the effort is manageable. Your team provides the information, we handle the management, and you make the decisions. Alternatively, if you optimize your HR concepts, you will be more deeply involved (health benefits, catering, etc.).
Is our location suitable for certification?
In most cases, yes. Together, we will analyze your current situation, uncover your potential, and develop a feasible path toward certification.
