In an already complex world, where the ever-increasing technological advances impose hectic daily rhythms and contribute to the detachment of human from the environment, there is an urgent need for humans to return to nature, to its simplicity and reconnect with it.

SUM wants to cross this boundary and create a new environment where humans, plants and animals all flourish, an environment where each of the groups benefits from the presence of the other. This is what we call:

Symbiosis

2 Challenges

1 Million Home Challenge

To facilitate the population growth in the Netherlands and the enormous housing shortage, 1 million extra homes are needed by 2030.

Climate-Neutral by 2050

To combat climate change, the Dutch government wants to become climate neutral by 2050. There 1,5 million homes should become more sustainable.

1 Million Home Challenge

To facilitate the population growth, 1 million extra homes are needed by 2030.

Currently, the population of the Netherlands is growing and society is becoming even more individualistic, which is most visible in the regions of Amsterdam, Rotterdam and The Hague. The Netherlands is undergoing an enormous housing shortage. In 2019 there was an estimated shortage of 263,000 homes. To facilitate this growth, more than 1 million residences are needed by 2030.

2030

49% less emissions

The Dutch Government wants to reduce the gas emissions by 49% by 2030.

1,5 million homes

1,5 million homes should become sustainable and net-positive in order to omit the emission of 3,4 megatons of CO2 by 2030.

2050

95% less emissions

The Dutch Government wants to reduce the gas emissions by 95% by 2050.

Climate Neutral by 2050

To combat climate change, the Dutch government wants to become climate neutral by 2050.

Europe aims to have a climate-neutral economy by 2050. Therefore, the Dutch Climate Agreement aims to reduce the gas emissions by 49% before 2030, and 95% before 2050. This means that there is a need to omit the emission of 3,4 megatons of CO2 by 2030. Therefore, 1,5 million homes should become more sustainable before 2030.

Redefining the way we build

Both our buildings and our communities

In order to overcome these challenges, SUM will tackle the alarming state of Dutch post-war neighborhoods by focusing on tenement flats constructed between 1945-1974. In the Netherlands, there are 847,00 tenement flats, which represent 11% of the total housing stock.

By addressing this typology, this integrated design will create a platform that strengthens the local community and encourages young adults to adopt new and sustainable habits. We aim to create a symbiotic breeding ground that leads to affordable, living communities, and a sustainable environment.

A framework that can be used across the Netherlands

By addressing the tenement flats, SUM will create a system that can be used across post-war neighborhoods in the Netherlands. This will not only ensure greater social, environmental, and economical impact, but will also provide the Netherlands with multiple strategic scenarios of implementation.

A community built on sustainable living habits

With our tenement flat repurposing strategy we would like to make a world where diversity, innovation and social interaction are stimulated. Where clever design solutions can tackle social, economic and environmental challenges.

Stimulation of social interaction

A net-positive renovation

Addition / Top-Up

These are the tools at our disposal

Modularity

Our design adopts wide use of prefabricated, modular and standardized components, realizing the building as a kit-of-parts.

Circularity

We are using products that can be reused in the future. We also encourage residents to live a circular lifestyle.

Social Cohesion

An environment where humans, plants and animals all flourish and benefit from the presence of the other.

Standardized

A framework that will provide the Netherlands with multiple scenarios of implementation that can be implemented across post-war neighborhoods in the Netherlands.

Net-Positive Design

A net-positive renovation strategy for 847,000 underperforming tenement flats that contribute to a positive urban and social living environment.

Affordability

Affordable housing will help ensure the built of this design, while also making these sustainable households available for everyone.
