What is an extension or loft worth in Andorra?
These are works to a house
Extensions, lofts, garage conversions and annexes assume a property you can build on or into — a house, bungalow or cottage with its own footprint. None of them applies to a flat or an apartment, where the floor area is fixed and the fabric is shared. The £/m² basis below is the whole island's stock, flats included.
Space in Escaldes-Engordany is asking about €8,384 per m² (63 listings there publish a floor area). Build costs below are published per-m² ranges. Neither is a quote, and value added is never the whole story — the first extension on a small house adds more than the third on a large one.
| Work | Size assumed | Likely build cost | Value that space would ask | Difference |
|---|---|---|---|---|
| Demolish and rebuild | 140 m² | €392,000 | €1,173,760 | +€781,760 |
| Two-storey extension | 45 m² | €99,000 | €377,280 | +€278,280 |
| Single-storey extension | 25 m² | €60,000 | €209,600 | +€149,600 |
| Annexe or outbuilding converted space, valued at 75% of the local rate |
30 m² | €63,000 | €188,640 | +€125,640 |
| Loft conversion converted space, valued at 85% of the local rate |
22 m² | €38,500 | €156,781 | +€118,281 |
| Garage conversion converted space, valued at 70% of the local rate |
16 m² | €20,000 | €93,901 | +€73,901 |
What this is doing, exactly
- Value is the local asking rate per m² multiplied by the space added — discounted for conversions, where a converted garage or loft does not fetch what new build does.
- Cost is a published per-m² range for that kind of work. It excludes professional fees, planning fees, VAT or GST, and anything the drawings show that the description does not.
- Granted is this island's own record for that kind of application. It is not a prediction about yours.
- A positive difference is not a profit. It ignores the cost of money, the months of disruption, and the fact that a buyer pays for a house, not a spreadsheet.
