The Architecture Foundation is seeking last minute pledges to support its 20-year digital archive project.

To celebrate its 20^th birthday in 2011, the AF is creating an online archive reviewing two decades worth of public programme and advocacy, including schemes by world-leading architects.

Any donations made to the project will be doubled and companies pledging more than £50 will have their website linked from the AF’s online archive.

So far £2,626 has been raised and you can add your pledge here.
