# Apartments

The endpoint described in this section applies to **apartment units within multi-unit residential buildings**. These include:

* Galerijflat
* Portiekflat
* Maisonnette
* Benedenwoning
* Bovenwoning
* Portiekwoning

The model assumes a **dwelling within a multi-unit residential building**, where roofs, walls, and installations may be shared with other units. The **position of the apartment within the building and the number of floors** are important factors, allowing the API to estimate insulation levels, heating systems, and other measures based on building characteristics and machine learning predictions.
