Add space with an understanding of the existing structure
Creating more living space in Utrecht may start with a different layout, an extension or a roof alteration. Feasibility depends on the existing structural system and foundation information. Compare local housing figures for orientation, then share drawings and photographs of your own home. For an opening in a wall, include the floor direction, bearings and any earlier alterations in the discussion.

Soil and ground types
Within the boundaries of Utrecht, map unit Rv01C covers the largest measured area of soil polygons in this analysis: 12,293 hectares, or 10.8% of the mapped area.
Original Dutch source name:
Kalkloze drechtvaaggronden; profielverloop 1
| Map code | Dutch soil classification: first unit | Area (ha) | Share of mapped area |
|---|---|---|---|
| Rv01C | Kalkloze drechtvaaggronden; profielverloop 1 | 12,293 | 10.8% |
| Rn47C | Kalkloze poldervaaggronden; zware klei, profielverloop 3, of 3 en 4 | 6,269 | 5.5% |
| gY30 | Holtpodzolgronden; grof zand | 4,984 | 4.4% |
| Zd21 | Duinvaaggronden; leemarm en zwak lemig fijn zand | 4,656 | 4.1% |
| ohVb | Koopveengronden op bosveen (of eutroof broekveen) | 4,507 | 3.9% |
| Other units | Other mapped soil polygons | 81,580 | 71.4% |
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 Utrecht. 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.
