A screenshot by David Lindop of MediaVest Manchester, revealed -- "double column Google search results." To be exact the screenshot seems to be of double column (and double spaced) Google sitelinks for a branded search.
Lindop suggests that these are not actually sitelinks, but more like deep links for that website. Also, it is debatable whether 'smart new homes' counts as a branded search or a generic one, as the concept of 'smart home' is increasingly being discussed in clean-tech circles.
He also notes that this results format aggressively pushes every other result down the page.
