éénniveau

Éénniveau is a Dutch term used in architecture and real estate to describe a building whose living spaces are arranged on a single floor, without intermediate stairs to upper or lower levels. The word is formed from één (one) and niveau (level), with the latter borrowed from French. In Dutch usage, éénniveau typically refers to a house or apartment designed for one-storey living, often marketed for accessibility or ease of use.

In practice, éénniveau properties are commonly associated with bungalows or single-storey homes. They may feature open-plan layouts, direct access to outdoor spaces, and wide doorways or hallways to accommodate mobility aids. The concept is frequently highlighted in regional housing discussions as a way to improve livability for older adults, families with young children, or people who prefer minimal stairs.

Design considerations for éénniveau buildings include footprint and site planning, as a single level may require a larger horizontal area than a multi-story equivalent. Accessibility features, daylighting, and energy performance are often emphasized, alongside storage solutions and vehicle access. While the single-floor format offers practical benefits, it can limit opportunities for multi-bedroom separation or views that are commonly provided by upper floors.

The term is used primarily in the Netherlands and Flanders (Belgium) and is commonly found in real estate listings and architectural discourse. It is often contrasted with multi-level or split-level designs that use additional floors to create separate living zones.
