The universe of viable options for large occupiers is much smaller than headline availability suggests.

Savills Research has released a new report examining the scarcity of large blocks of office space in most markets, particularly once quality, location and landlord financial stability are considered.

The analysis spans 16 North American markets, measuring the share of office buildings offering a contiguous 50,000-square-foot (sf) block and how that share narrows as increasingly selective criteria are applied.

With occupier demand concentrating in premium buildings, financial distress complicating leasing decisions and the development pipeline at historic lows, competition for the most desirable space is intensifying.

For large occupiers, the challenge is no longer simply finding available space. It's finding the right space.
