Supply Pipeline vs Net Supply: How to Read a Development Tracker
A development pipeline is announced supply; net supply is what actually gets added. Why the two diverge, and what Riyadh's office numbers do and don't show.
A development pipeline is the total supply announced or under construction; net supply is the amount that actually reaches the market after delays, demolitions, withdrawals and conversions. Treating the pipeline as if it were net supply is the most common way to over-estimate how much a tight market is about to loosen.
Why the two numbers diverge
A pipeline figure is a promise. Net supply is what gets delivered and stays deliverable. Between the two sit several leakages:
- Slippage. Projects announced for one year arrive one or two years late, or split across phases.
- Withdrawal and re-purposing. Schemes are cancelled, mothballed, or converted to another use.
- Demolition and removal. Older stock taken offline nets against new completions. Net additions equal gross completions minus stock removed.
- Double counting. The same tower appears in successive "upcoming supply" figures until it finally completes.
The practical rule: gross pipeline is an upper bound on new supply, not an estimate of it. In a market clearing at near-full occupancy, the gap between the two decides whether next year brings relief or none.
An illustrative example
Round figures, for the mechanic only. Not market data. A city has 500,000 sqm announced for delivery next year. History says a third slips to the following year, one scheme of 50,000 sqm is cancelled, and 40,000 sqm of tired stock is demolished. Net supply is not 500,000 sqm. It is roughly 500,000 − 165,000 (slippage) − 50,000 (cancelled) − 40,000 (demolished) ≈ 245,000 sqm, under half the headline. An occupier planning around the 500,000 figure would badly misjudge the market.
The Gulf reality: Riyadh's office pipeline
The primary record gives you the gross announced pipeline clearly, from developers and their owners themselves. The largest confirmed scheme is New Murabba, with 1.4 million sqm of office space inside a 25-million-sqm downtown, targeted for delivery around 2030 (PIF / New Murabba). The already-built prime cluster, KAFD, carries over 900,000 sqm of office space across 95 buildings (KAFD; PIF). For a sense of scale against standing stock, a single listed fund, Riyad REIT, holds 799,463 sqm of net leasable area (Riyad REIT, Dec 2025). Those are gross, announced or standing figures.
What the record does not publish is Riyadh's net additions, the pipeline after slippage, withdrawals and any stock taken offline. No government body, exchange filing or developer states a city-wide "net new office supply per year," and the market-wide completion series that private brokerages sell is exactly that, proprietary, so it is excluded here. That distinction carries real weight. A scheme like New Murabba is a 2030 target, not 2026 supply, and between announcement and delivery the usual leakages apply. Against a prime cluster already two-thirds leased and listed landlords reporting their Riyadh offices at or near full (see Riyadh office market), whether a given year's announced pipeline nets to most of its headline or a fraction of it is the difference between modest relief and none. Reading a pipeline tracker without the net view is a trap. Pair this with absorption rate: pipeline tells you what may arrive, absorption tells you how fast it will be taken.
FAQ
What is a real estate development pipeline? The total stock announced, approved or under construction for future delivery in a market. It is a forward count of intended supply, not a guarantee of completed supply.
What does net supply mean? The actual net change in available stock over a period: gross completions minus space removed through demolition, withdrawal or conversion. Net supply is what a market truly has to absorb.
Why is net supply lower than the pipeline? Because of project slippage, cancellations, phased delivery, double-counting across reports, and demolitions that offset new completions. The pipeline is an upper bound.
What is Riyadh's net office supply for 2026? Not published by any public source. Developers disclose gross announced schemes (New Murabba's 1.4 million sqm of office, targeted for around 2030; KAFD's 900,000+ sqm already built), but the net annual addition after slippage and withdrawals exists only in private brokerage models.
