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:

1. **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).
2. **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.
3. **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.
