Extending a property is a popular way for Calpe homeowners to add space without the disruption of moving. Here's what genuinely affects the cost.
What Determines Extension Cost
The size of the extension, its complexity (single storey versus multi-storey), foundation requirements, and the finish level all influence the final price. Extensions that connect seamlessly to the existing structure typically cost more than simpler additions.
Typical Cost Factors
- Size and footprint of the planned extension
- Foundation and groundworks needed for the site
- Roof type and how it ties into the existing structure
- Finish level — from functional to high-end matching the rest of the property
- Services — plumbing and electrics extended into the new space
Planning and Licensing
Extensions in Calpe require a building licence from the local ayuntamiento, along with architect-drawn plans for anything beyond minor works. We coordinate this process as part of every extension project.
