Large office transactions are back on the table in Europe, says Savills, as cross-border investors increase their allocations into the sector.

In its European Office Investment report for the third quarter of 2025, the advisory firm says the number of office investment transactions over €50 million has risen by 43 percent year-over-year, as investors become more willing to deploy on larger lot sizes.
