The market for prime residential property in central London is facing noticeable challenges. The number of completed but unsold flats has tripled since 2016. By the end of September, unsold inventory across central locations totalled 1,400 units.
Significant decline in construction starts in Zone 1
Buyer reluctance is leaving a clear mark on developers' planning offices. In London's Zone 1, construction starts plunged by 75 per cent over the course of the past decade. What was considered one of Europe's most active prime markets for years is thus experiencing a fundamental slowdown in new development activity.
Two key developments are primarily responsible for this drop: developers face markedly higher development and delivery costs, while buyer interest has cooled at the same time. The interplay of these factors means that new projects are increasingly being postponed or reassessed for their commercial viability.
Tied-up capital and a changing market environment
The rise to 1,400 completed units ties up considerable capital for development companies. In the current financing environment, sluggish sales in the prime segment are proving a severe test, as standing inventory generates ongoing holding costs and restricts liquidity for future schemes.
- —Unsold completed stock triples since 2016 to reach 1,400 units
- —75 per cent drop in Zone 1 construction starts over a ten-year comparison
- —Ongoing cost pressure for developers alongside subdued demand
The figures illustrate that the central London residential segment is undergoing a period of profound consolidation. While developers are drastically scaling back new projects, the swift absorption of existing vacant stock in the premium segment remains the primary task for the coming quarters.
