Silent Night at Dennis Severs' House

I've never been inside the house but went by it on a walking tour a few weeks ago. Severs essentially decided that he was living in the wrong century and sought to recreate the olden days in his house. Sure, the period decor is one thing (although note: not all items are artifacts; many are imitations hand-made by Severs which actually delayed the house's recognition), but he also spurned modern heating, lighting, and plumbing...it's a true walk through time. He created a fictional (though plausible) family to live in the house with him whose silhouettes you can see when walking by outside. Having never been, I'm not sure if it's worth the entrance, but if you've a spare few hours, why not?

Good evening, I like to get about a bit and Dennis' house sounds lovely, but why is he getting top billing here? Being more of a west end girl, I'm not sure if this is some famous old stiff's house with a blue plate: or just some self promoting new brit artist who died here (no doubt choking on his own vomit or pug dog) and his pals have done the old place up for a giggle? Can anyone enlighten me as to who Dennis is (or was) and why I should visit when there are soooo many other interesting things to do in the east end? Many thanks Sadie x
