Good examples
Hovinbekken, Oslo – reopened waterway as a premise
What does the case show?
Open, nature-based stormwater solutions (stream opening, diversion in green areas) that simultaneously provide flood mitigation, a cooling effect, natural diversity and recreation.
This example shows that NBL is not “decoration”, but a guiding premise for location and design – with benefits for both operations, risk and site quality.
What can be transferred to holiday home fields?
Direct roof and surface water in an open chain (rainbed → vegetated ditches → sunken greenway), reduce pipes/culverts.
Use edge zones and vegetation for infiltration and erosion control.
Plan common green/blue structures early, not as "landscape additions."
The Tree Cube, Höga kusten – "easy on the ground"
What does the case show?
Minimal footprint, terrain adaptation and nature integration: construction that follows the site and preserves vegetation/soil.
Exemplifies the basic idea in NBL for buildings: avoid and limit interventions before "adding" natural measures - reversibility, small volumes, point/screw foundations.
What can be transferred to holiday home fields?
Choose a location/method that minimizes mass displacement (build in micro terrain).
Use point foundations rather than poured slabs; preserve edge vegetation and trees.
Think "small, low, portable" as standard — nature tolerates it better, operation becomes easier.

Questions that are recommended to be discussed initially
What natural challenges are we dealing with (stormwater, erosion, heat, biodiversity)?
What ecosystem services already exist on/near the site – and how can we enhance them?
At what scale do we need to think for the measures to work (plot, sub-area, field, landscape)?
What is the project's level of ambition (avoid–limit–restore/enhance)?
What risks (floods, landslides, marshes, wetlands, vulnerable species) must guide choices and deselections?
How must the construction phase be adapted (season, access, soil compaction, establishment care)?
Proposal for role distribution
SME (developer/contractor) : Propose level of ambition, identify benefits/costs, describe early NBL opportunities and opt-outs; plan for construction phase and maintenance.
Municipality/administration : Clarify relevant goals/requirements/consideration zones; point out risk factors; ensure that NBL is assessed from the start; clarify expectations for documentation.
Professional resources (consultants/architect/landscape architect) : Translate ambitions into feasible measures; contribute with map basis and principle sketches.
