Find your settlement within its municipality

Friesland contains many officially registered settlements within larger municipalities. You can therefore search below using either a municipality or village name. The population shown in a municipality profile covers its entire administrative area. Preparing an alteration requires records for the individual house: the address, existing plans, photographs of the structure and a sketch of the proposed layout. This keeps the step from regional information to a specific building project clear.

Soil and ground types

Within the boundaries of Friesland, map unit Hn21 covers the largest measured area of soil polygons in this analysis: 19,767 hectares, or 6.1% of the mapped area.

The shares are calculated within the soil polygons on the map, not across all land or all building addresses. For compound map codes, the name of the first unit is shown. The map describes shallow soil; built-up areas are not fully mapped. It does not establish bearing capacity or determine whether piles, pad footings or strip foundations should be used.

How much renovation takes place?

The CBS tables used here do not provide a complete local renovation count for Friesland. We therefore do not estimate this from population, new homes or a national percentage. These sources also do not establish which type of renovation is most common.
