Campaigners sought protection for Argyle House, the 1960s brutalist block on West Port, after plans emerged to demolish it for a major mixed‑use redevelopment including a hotel, homes, offices and retail. The building, long derided as one of Edinburgh’s “ugliest”, has twice been rejected for listing before, in 2007 and 2008.

HES said its latest assessment found Argyle House to be a significant example of Scottish Modernism, noting its flint panels echoing Castle Rock and sandstone detailing designed to sit alongside neighbouring 19th‑century terraces. It also described the block as a rare surviving large‑scale office development of its era.

However, the heritage body said it would not proceed with listing while redevelopment proposals are already at an advanced stage.

Built between 1966 and 1969 for government offices, Argyle House was sold to US firm PGIM Real Estate for around £38m in 2023. It is currently leased to CodeBase until 2033. Developer Hendersonherd says plans are being brought forward ahead of the lease ending to ensure the site continues to deliver economic benefit.

The building has appeared on screen as the police HQ in Dept Q and as the fictional Lothian Police headquarters in Irvine Welsh’s ITV drama Crime.
