  • Sustainable building
    You invest in a nature-inclusive wood building with a vegetable garden and a roof on which we generate our own energy via solar panels. In winter, we will heat our house via heat pumps and within our plants on our facade we will create as many nests for animals as possible.
  • Social community
    Your investment supports a permaculture community caring for each other, the neighbourhood and the city. We share things and spaces in the community in which we create places for the neighbourhood to come together and make the city more beautiful through workshops, repair cafes or a neighbourhood kitchen.
  • Affordable housing, partly for people who are having an extra hard time on the housing market
    You enable affordable social and middle rent, part of which is earmarked for people who are having an extra hard time in the housing market. These remain affordable rental properties in perpetuity and can never be sold.
  • More housing cooperatives in the Netherlands
    By investing in us, you not only make the construction of our housing cooperative possible, but also that of many projects in the future. Every euro of profit we make from our project goes into a fund for housing cooperatives to make even more great projects possible.

Our investors about our cooperative
What is a housing cooperative?
A housing cooperative is a coalition of people who desire to manage their own houses in a social way, guided by the needs of the collective. As members of a housing cooperative in formation, we collectively design our new dwelling and again collectively build and maintain our property. An important aspect here is that on idealistic grounds no profit will be made at the cost of the tenants, that is, the members of the cooperative.

In both Germany and Switzerland this form of housing is already widely deployed as a means to ease the pressure on the housing market, to help it become a little more healthy. The municipality of Amsterdam is now also active in this field, and sets out to realize 40.000 houses of the cooperative kind by 2040, making up about 10% of new construction up to that year. The recently published Actieplan wooncoöperaties clearly outlines the municipality's ambition in this matter.

Housing cooperative De Torteltuin
How do we want to live later in life? This question planted the first seed for De Torteltuin. The answer: more affordable, social and green than what we can find in Amsterdam at the moment. What we want does not exist yet - so we will build it ourselves, as a collective.

Because we view ownership over houses neither as the holy grail for individuals, nor as a sustainable model for society, we are doing this as housing cooperative: development, usage and management are in the hands of the actual group of cohabitants. The appartements which we are building are going to be protected against the vagaries of the market with a fixed, low rent - a house is after all a basic right, not a tool to invest. Next to that our future house will be a beacon for communal living: we will share a lot of facilities with each other and we are making democratic decisions on the running of the housing cooperative. And all of this within the realms of a energy-neutral, climate-proof and nature-inclusive building! Because by looking further than the moment when the building will be finished, we are looking at the long term value that our housing cooperative can create for her inhabitants and her neighbourhood.

From the first brainstorm in January of 2020 we have come far:
In 2022 de Torteltuin has signed an agreement with the municipality for the development of a plot on
Centrumeiland, IJburg, in Amsterdam. In October 2023 we got the loan of the Stimuleringsfonds and now we have a beautiful final design of our building which we created together with Natrufied Architecture.
Also we are going to work hard on the bond campaign in the upcoming months and the start of construction is planned for the beginning of 2025.
