NewGround is a new formula designed to break with market conventions. Created by the Netherlands’ leading real estate legal professionals. Together they are bringing more than one hundred years’ experience in representing a wide range of clients.

Their purpose is clear: they focus on what really matters. And if necessary, they simply take an entirely different approach. With focus and incisiveness. And with a priority on the human dimension. Just as today’s world demands. That means a different DNA. Because they firmly believe that their clients’ interests are best served by adopting a deeply rooted ‘human-centric’ approach. A philosophy that may not necessarily be supported by everyone. But one they believe will attract the right people. People who want to be associated with the New world: new clients as well as future colleagues.

NewGround is specialized in providing legal services in the real estate sector and the spatial environment in the broadest sense, including environmental and energy law and sanctions.

They focus on corporate and other large commercial transactions, disputes and legal consultancy. They are specialized in contract law, notarial law, construction law, tenancy law, planning law, nature conservation law and (sustainable) energy and environmental law including sanctions as well as criminal enforcement. In addition, they keep abreast of the latest trends and developments in topical issues, such as sustainable construction and Clean Tech, the energy transition and smart cities.

Main areas of practice
Administrative and sanction law: Administrative law governs the relationship between people and government. It regulates the actions of government agencies when making administrative decisions. As each situation is different, the applicable legislation and regulations are often layered and diffuse.

Construction law and contracting: Principals and contractors are advised on their rights and obligations under construction law. They also have substantial experience in drawing up building contracts for commercial property and housing complexes. In addition, disputes are handled and litigated at the Arbitration Board for the Building Industry.

Contract and notarial law: Real estate law is inextricably linked to contract law. NewGround assists in laying down in writing arrangements in a lease or sale and purchase agreement or a contract for professional services. In addition a multi-disciplinary team consisting of attorneys and (candidate) civil-law notaries handle large and complex real estate transactions regarding the sale and acquisition of immovable properties and real estate portfolios in various sectors, starting out at the early stage of (commercial) negotiations with advice on the letter of intent. They carry out due diligence to identify potential risks for the client, accompanied by proposals for mitigating them. The notarial experts also take care of the legal transfer of the real estate.

Property law: NewGround advises on (the creation of) the various rights, such as the right of ownership, leasehold, right of superficies, easements, common ownership and apartment rights. Property law demands clarity in the rights and obligations of the various parties involved, including leaseholders, landowners, neighbors, owners of apartment rights and Owners’ Associations. For leaseholds specifically they advise and litigate on matters related to risk, centering on leasehold conditions, ground rent increase and valuation.

Tenancy law: Issues related to letting and leasing are often complex. They advise clients on office and commercial premises, the conclusion of leases and regarding lease terminations as well as complex issues in current contracts, sometimes resulting in litigation when the need arises.

Environmental law: Environmental law consists of a large number of laws and decisions that are all important for ensuring a healthy environment. The Environmental Management Act is central to environmental law. It serves as a framework act for permit applications in case of (industrial) activities that might result in environmental impacts.

(Sustainable) energy and regulatory law: Realizing the energy transition requires an interdisciplinary approach to law. In the coming decades, the Netherlands awaits a complete change in the field of generation, transport, storage and saving of energy. NewGround helps its clients in this highly regulated market.

Planning law: The Netherlands is a densely populated country. That places considerable pressure on the use of physical space. NewGround advises you on all aspects of environmental and planning law, including spatial planning, area development and environmental and nature conservancy legislation. Matters that need to be understood before you embark on the development of new real estate projects, such as transformation of existing buildings, development of sustainable energy and land, including municipal cost recovery.
