Turning our (somewhat wandering) attention back to HostelBloggers’ HQ, this weekend sees a London event that’s sure to catch the eye of budget-conscious travelers and locals alike: Open House London.

The Open House London weekend (20-21 September) essentially does pretty much what it says on the tin – it allows the public a rare (annual, actually!) glimpse of some of the capital’s most unique and fascinating architecture.

Highlights include the brand-new Willis Building, which graces the skyline of the Square Mile, the iconic modernist Highpoint flats in N6 and the developing site of the 2012 Olympics.

But that’s just the beginning – there’s actually a grand total of 699 houses, offices, banks and every other imaginable type of structure to visit, many of which are closed outside of this weekend. It’s worth pointing out, however, that some are only accessible as part of Open House tours (bookable on the Open House website).

And the best news? Absolutely all this design, culture and architecture comes without you even having to put your hand in your pocket!
