# Rebuild Value API

### Calculating the rebuild value

Welcome to the documentation for the Rebuild Value API. This API enables developers to calculate the rebuilding value of houses, a crucial factor in determining the insured sum for building insurance policies. In this documentation, we discuss key concepts, how to use the API, and the expected response.

**Overview**

The rebuilding value of a house is the amount needed to rebuild the house in case of total loss, such as by fire. It is expressed in euros and is based on the volume of the house in cubic meters and the average construction costs per cubic meter.

**Key Concepts**

* **Rebuilding Value Meter**: A tool to calculate the rebuilding value. It takes into account the type of house, the volume (in cubic meters), and the finish. It also provides a guarantee against underinsurance, meaning that in case of damage, full costs are covered even if the rebuilding value was underestimated​​.
* **Average Construction Costs**: These vary by the type of house. For example, for a terraced house, this is often € 490 per cubic meter. This calculates a basic rebuilding value including a standard kitchen, bathroom, and living room finish​​​​.
* **Surcharges and Discounts**: More luxurious finishes such as kitchens and bathrooms or special features like a different facade or roof can lead to surcharges on the calculated value. Discounts may apply if the house is built on sand or certain elements like piling are not insured​​​​.

**API Usage**

* **Endpoint**: The API offers an endpoint where you can send a POST request with details about the house, such as its type, volume in cubic meters, and any special features.
* **Response**: The API will return a JSON response with the calculated rebuilding value, including any surcharges or discounts.

**Frequently Asked Questions**

* **How often should the rebuilding value meter be filled out?**\
  To continue being eligible for the guarantee against underinsurance, it is recommended to fill out the rebuilding value meter every 5 years​​.
* **How is the volume of a house calculated?**\
  The volume is calculated by multiplying the length, width, and height of the spaces. Calculating this can be more complicated with sloped roofs, but this information is often available in the house's documentation​​.
