Building the future
we want to live.

We believe that people and planet should not pay the high price of traditional, commercial development. Over 20 years ago, we embraced circular principles and we’ve been creating beautiful, functional, sustainable logistics, office and residential space ever since.

For us, a successful building is one that functions exceptionally well, makes little environmental impact, leaves a positive legacy and pleases people. We design for all the senses, because good buildings make people happy, productive, inspired and connected to their surroundings. That’s the future we all want to live, so that’s what we build.

Past, present, Future Forever.

Delta began developing in 1988, and in 2000 we discovered the Cradle to Cradle philosophy: everything is a resource for something else, everything can be designed to be disassembled and safely returned to the soil, or to make new materials or objects.

Today we work in the Netherlands and Germany to create modular, dismountable buildings, and innovative leasehold models that cut waste. We work in creative partnership with clients, architects, investors, municipalities and collaborators to embed positive principles in the world we’re all building, together.

a world we're building together

Our projects

All of our projects are delivered to a framework that ensures a positive legacy.

Future Forever - our manifesto for the world we want to build.

Our world needs bold change and people and industries willing to drive it.

20 years after committing to only using circular design principles, we’re making an ambitious promise that recognises our responsibility to future generations and embeds it into everything we do.

This is our promise to the world.

Future Forever

Cradle to Cradle® – our founding philosophy

One of the first practices to adopt C2C, we continue to work to William McDonaugh’s pioneering circular design principles. In 2000, the idea that ‘everything is a resource for something else’, was exciting and inspired the mindset that still defines our work – what we are building today are the ‘materials banks’ of the future.

UN’s Sustainable Development Goals – our compass

In September 2015, all 193 member states of the United Nations adopted a plan to achieve a better future for all. "Agenda 2030" sets out a path to fight injustice and end extreme poverty, inequality and to protect our planet over the next 15 years. At the heart of this plan are the 17 Sustainable Development Goals (SDGs) that clearly define the ideal world. They apply to all countries and leave no one behind. We use the SDGs as our compass. That is how we are helping to build the future we want to live.

Clean Water and Sanitation

Ensure access to water and sanitation for all

We treat water as the precious resource it is, using Cradle to Cradle certified products and strategies.

We embed grey water management and recycling into our projects, and even sewage processing through natural helophyte filters.

Affordable and Clean energy

Ensure access to affordable, reliable, sustainable and modern energy

All of our projects are energy neutral. We power developments with renewable energy to positively impact ecosystem balance and keep carbon in soil and vegetation. We constantly push the limits of what’s possible in sustainable energy and enhance the energy efficiency of our buildings. We invest in and promote clean energy technology.

Decent work and economic growth

Promote inclusive and sustainable economic growth, employment and decent work for all

Social fairness is a driving force for Delta. It’s reflected in our commitment to Cradle to Cradle and C2C certified products, which ensure that the sourcing, production and processing of materials is fair and sustainable; but it’s also embedded in our own practice. Delta stands for fair wages and a transparent, fair distribution of profits along our whole supply chain, as well as shared responsibility in every project.

Industry, Innovation and Infrastructure

Build resilient infrastructure, promote sustainable industrialization and foster innovation

We share all our knowledge around sustainability, circularity and C2C practice.

This to enable others to make development more sustainable, and to work progressively, together, to find ways to cut and eliminate the need for raw materials.

Sustainable cities and communities

Make cities inclusive, safe, resilient and sustainable

This chimes so closely with our mission to only put good into the world, not just for developers and investors, but for all, and not only for now, but the future. We build for disassembly, in effect creating a ‘materials bank’ in every project. We work with clients with a shared commitment to environment and air quality, indoors and out – our human-centred approach puts people, health, wellbeing and their productivity at the heart of each project.

Responsible Consumption and Production

Ensure sustainable consumption and production patterns

The C2C philosophy we work to assumes that waste does not exist.

It sees natural materials used in such a way that they can eventually return to nature cleanly, and technological materials, such as steel, created and used to be reused in their original composition.

In this neutral ecological footprint, waste does not exist: that’s what we’re committed to.

Climate Action

Take urgent action to combat climate change and its impacts

We are optimally reducing fossil fuels as an energy supply for our buildings and in the production process of materials and construction.

Our solutions are focused on maximally reducing CO2 emissions and we relish the chance to partner with others to explore ways to do this innovatively and progressively.

Life below water

Conserve and sustainably use the oceans, seas and marine resources

C2C requires responsible use of water and natural resources, including that water that is used during the construction and use of a building is purified before returning to nature. Toxic materials and plastics are avoided – if they are unavoidable they are disposed of responsibly, so that we can be sure we are not contributing to river and ocean pollution.

Life on land

Sustainably manage forests, combat desertification, halt and reverse land degradation, halt biodiversity loss

In our project development we always take into account the ecological situation on site, to protect flora and fauna. We never see a project separate from its environment and take great care of the surrounding vegetation and the ecosystems it supports. We prefer not to develop greenfield, instead re-using existing buildings or locations.

Xander van Hoof

Project Developer

Our projects provide inspiration and new faces. For instance, the sustainable redevelopment of the Fokker factory site was reason for Xander to choose Delta in 2005.

A great challenge because innovation in sustainable real estate demands the utmost from specialists like Xander.

Fokker Logistics Park became a spectacular project where continuous new challenges had to be managed. It required patience, perseverance, overview and creativity to optimise the logistics buildings with the application of the Cradle to Cradle philosophy. This experience is now extremely useful for new developments.

Dave van der Werff

After working as a project manager for a large housing project developer in North Rhine-Westphalia, Julian has found a new challenge at Delta in Düsseldorf.

As an architect, it is important to him to create added value for urban space and people while the real estate agent in him finds it important that building projects are also realised economically and sustainably.

He believes in the responsibility everyone has to be conscious of the resources available to us. This is why he is very interested in developing buildings that positively affect people.

Philipp Sonneck

Joost van Loon

Branding and communications consultant

Joost werkt sinds 2017 voor Delta. Na ruim 20 jaar zelfstandig documentaires maken over klimaat, duurzaamheid en water werd zijn interesse gewekt voor Delta vanwege de toepassing van Cradle to Cradle en de centrale plaats die duurzaamheid inneemt in de aanpak van Delta. Dat betekende dat hij, ook al omdat hij graag weer eens in een team wilde werken, na zo’n 30 jaar weer terugkwam in het vak waarvoor hij gestudeerd heeft: marketing en branding. Het enthousiaste gevoel voor Delta is vanaf die eerste dag niet meer weggegaan.

Patrick van der Wulp

Project controller

Keeping the reins in hand and making sure each project stays financially within the set guidelines is important to Patrick.Rigorous, accurate, thorough but with an innovative slant where sustainable solutions are applied. Less paper, digitisation, energy-efficient equipment, not always being stuck in traffic jams but also working from home.Because sustainability is key at Delta, it is also becoming more and more common sense at home.

Because that's what Delta is all about.It means continuous investment in new techniques, new processes and different ways of thinking.As controller, Sander plays a (pro)active role in this. That was therefore the reason for him to join Delta to reflect on the financial challenges posed by new plans.
