I was just skimming ebay like I normally do throughout the day and noticed they have started a new listing page style. Not sure if I am lucky or if eveyone has it, kinda interesting with the bigger listing but cluttered. And no this isnt a Chrome Extension.
I tried to duplicate the page you're showing, but to no avail. I thought maybe the European format may have changed, but I all the pages I view are still the same. I'm sure there's a simple answer to this.
Found it... a "new" search page experience. You have to "opt in" or pages display in the older format. http://pics.ebaystatic.com/aw/pics/search/garden/preview_experience_screenshot.gif It's the third option down in the right hand column: http://garden.ebay.com/
