In addition, we are specialists in selling and optimizing surplus real estate and in sale & leaseback constructions of strategic real estate. In these processes, Marble is a professional and pleasant collaboration partner who thinks along creatively, acts quickly and unburdens. Together we achieve the optimal result that is in line with the organization objectives.

Offices / Industrial

For tenants or occupiers of commercial real estate, we create integrated housing solutions together with our trusted partners. This means that we are primarily responsible for the commercial advice in a lease or purchase acquisition process.

Depending on the clients’ needs, we can integrate additional services into the process with partners, from drawing up a program of requirements to turn-key delivery. We unburden our clients and optimize the end result.

Dit doen wij voor kantoorgebruikers en voor gebruikers van bedrijfsruimte en logistiek.

In addition, we are specialized in selling surplus real estate, sale & leaseback constructions, renegotiations and advising on lease termination situation



Thanks to our specific experience in advising healthcare institutions on commercial housing issues, we can provide a sustainable contribution to your real estate strategy in healthcare.

With our knowledge we look for optimal and feasible solutions with which we can optimize and implement in your strategy.

This may involve the (structured) sale of surplus real estate, redevelopment positions, sale & leaseback constructions and leasehold and purchase guidance. As part of our services, we often supervise the entire process with the national regulator (College Sanering Zorginstellingen).

    Kristian van Eijkelenburg studied Urban Planning at the Hogeschool Utrecht followed by a bachelor in Social Geography and a master in Real Estate Studies at the University of Groningen.

    He started his career in early 2008, at ING Real Estate Development as a junior project developer and account manager letting offices. In 2009, Kristian made the switch to BMC, a management and consultancy firm, where he focused on healthcare real estate and area development.
    With this broad background, Kristian started to focus on commercial real estate advice in mid-2010, and started working for Jones Lang LaSalle (JLL). He worked there for 2.5 years as a real estate consultant in The Hague region with a focus on leasing, rental and sales of commercial real estate and redevelopment projects. In 2013, he switched internally to the Corporate Tenant Representation Team. In this position he advised occupiers of real estate on leasing, renegotiation, sale & lease back transactions and redevelopment assignments. As Senior Advisor and Associate Director, Kristian has been responsible within this team for the regions of The Hague (3.5 years) and then Central, North and East Netherlands (2 years).

    Kristian set up JLL’s healthcare real estate division on his own initiative in 2018 and was ultimately responsible for this discipline. The focus was primarily on leasing, selling, purchasing and redevelopment assignments for healthcare institutions.

    With his more than 11 years of experience in commercial real estate, Kristian decided to start Marble Real Estate together with Joost Sweep in mid 2019.
