When we struggle to build an IKEA bookcase, we often wonder just how on earth architects and engineers manage to build something of actual, real complexity. There must be so many screws for a start.
And nowhere are there more impressive structures than in the great cities of the world, which boast an array of stunning and famous creations.
These posters, created by Swedish design agency Studio Esinam, celebrate the collected works of cities such as London, Tokyo and Stockholm, featuring a series of blueprints of structures that you will immediately recognise.
They retail for 950 SEK/£74 (65 x 100cm), or 650 SEK/£50 (50 x 70cm) - and if you get bored of them, you can always colour them in. Two for the price of one.
