This LEGO build by Pandora and Rufus is in the style and scale of the LEGO Architecture series that LEGO themselves release.
And actually it's rather surprising that LEGO hasn't done the Royal Albert Hall in their official line up because it's exactly the sort of architecturally interesting building that they tend to go for.
As you can see from the gallery below they've done a good job of capturing the structure and even the color of the building. You can see even more photos in their Flickr Photoset.
