A ‘granny annex’ (known in the Netherlands as a kangoeroewoning) is a form of living where two households live under one roof while maintaining their own independent living spaces. In the Dutch housing market, this is a popular way to provide informal care (mantelzorg) while ensuring privacy for both parties.
What is a ‘Kangoeroewoning’?
In the Netherlands, this usually involves a primary residence with a connected, smaller living unit. It is often a permanent structural part of the main house.
Key Features in the NL:
- Independence: Both dwellings usually have their own facilities, though they share the same plot.
- Internal Connection: A connecting door is typical for easy access during care-giving.
- Status: Unlike a temporary prefab unit, an annex is a permanent change to the building.
Dutch Legal and Tax Aspects
Even though you are providing care, the Dutch authorities have specific rules for these types of dwellings:
- Address & Registration: In the Netherlands, you must check if the municipality (gemeente) requires a separate house number or if you are registered as one household in the BRP (Basisregistratie Personen).
- Municipal Regulations: Each municipality has its own ‘Bestemmingsplan’ (zoning plan). Some allow ‘dubbele bewoning’ (dual occupancy) specifically for care purposes, while others are more restrictive.
- Tax & Benefits: Living under one roof can affect your Dutch taxes, AOW, or other social benefits. It is vital to check the ‘kostendelersnorm’ (cost-sharing standard) with the Belastingdienst.
Impact on Property Value
An annex is a long-term investment in Dutch real estate.
- Value Increase: Generally, the extra square meters of living space increase the WOZ-value of the property.
- Marketability: In the Netherlands, properties with an integrated annex are increasingly sought after due to the ageing population, though the target group remains specific.
Who is it for?
This solution is ideal if you are looking for a permanent structural solution in the Netherlands and your current home allows for an extension or internal conversion.
