Vrijburcht

A short description of the NBS project

Vrijburcht is a multipurpose living-and-working complex in Amsterdam created by residents as response to the expected impacts of climate change. The courtyard garden, composed of trees, lawns, flowers, benches and a greenhouse, provides solutions to prevent or reduce flooding from extreme rainfall, drought during dry periods and heat stress during hot summer days. In particular: • Rain water (from the roof tops) is collected in two tanks that are buried in the garden and it is used for irrigation of garden and plants on the surrounding terraces/balconies; • Car parking garage is created under buildings and garden is paved minimally to create maximum permeability for rain water; • Relief is created: water flows from higher parts to a marsh-like environment. This prevents flooding of the garden and enhances vegetation diversity by creating dryer and wetter environments across the courtyard garden; • Drainpipes are detached from facades at ground-floor level and together form a pergola construction for creeping plants. This minimizes the impact of potential leakages on the facades. Creeping plants are also used at the exterior of the building creating wind screens and green facades; • Many trees in the garden provide shade and thus contribute to an agreeable microclimate on hot summer days.

Cluster Governance Model Description
cluster4_societal_resilienceSelfgovernance_grassroots_initiatives Total costs of building complex were about € 16 million. Garden costs (about € 55.000 excluding rainwater storage facilities and greenhouse costs, respectively € 17.500 and € 30.000) were carried by all residents/users: garden was a collective wish of stakeholders and it was financed by them by making compromises in the overall complex design (the overall budget was fixed but the garden could be financed by economizing on other aspects of the building design). There was no subsidy involved. Instead Vrijburcht Foundation arranged with Rabobank the idea of personal loans (at favourable interest rate) and procedures for a special mortgage construction for people with an average regular income. Also the (social) housing corporation ‘De Key’ provided financial warranty and know-how. On annual basis, maintenance costs of the garden amount to € 3.000 (including the work of a gardener helping voluntary residents). Also costs of the maintenance are carried by the inhabitants and ‘De Key’ as part of regular service fees of the building, managed by homeowner association.

Business Model
Class Type Description
The main aim of the residents-to be for Vrijburcht complex was to offer an attractive and sustainable building for people to live, work and meet by creating a mix of affordable housing, ateliers/offices and public space.
