Consider design, ground data and the existing building together
Structural design in Gelderland starts with the relationship between a building and its ground conditions. Municipal tables combine the housing profile with measured soil-map areas. Use the map to frame investigation questions, and have the necessary foundation information established for the building address. For a wall opening, loads from the storeys above also matter; an extension additionally requires coordination between existing and new structures.

Soil and ground types
Within the boundaries of Gelderland, map unit Hn21 covers the largest measured area of soil polygons in this analysis: 42,819 hectares, or 9.3% of the mapped area.
Original Dutch source name:
Veldpodzolgronden; leemarm en zwak lemig fijn zand
| Map code | Dutch soil classification: first unit | Area (ha) | Share of mapped area |
|---|---|---|---|
| Hn21 | Veldpodzolgronden; leemarm en zwak lemig fijn zand | 42,819 | 9.3% |
| gY30 | Holtpodzolgronden; grof zand | 25,083 | 5.5% |
| gHd30 | Haarpodzolgronden; grof zand | 23,792 | 5.2% |
| pZg23 | Beekeerdgronden; lemig fijn zand | 23,323 | 5.1% |
| Rd90A | Kalkhoudende ooivaaggronden; zware zavel en lichte klei | 20,331 | 4.4% |
| Other units | Other mapped soil polygons | 324,659 | 70.6% |
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 Gelderland. 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.
