Last summer's sporting euphoria already seems like a distant memory, but the "legacy" of the Games is only just beginning. From July, the northern half of the Queen Elizabeth Olympic park will open up, complete with an adventure landscape by Erect Architecture – a wild world of ladders, slides and walkways winding through the trees. The Copper Box by Make Architects will also reopen, hosting everything from concerts to basketball and badminton. Queen Elizabeth Park, London E20 (noordinarypark.co.uk), July.

The Biospheric Project
Mushrooms bursting from bags, salad sprouting out of walls and chickens running free on rooftops will await visitors to a former mill in Salford in July. As part of the Manchester international festival, the building will be transformed into a multistorey hive of agricultural production. If you've never heard of agroforestry or aquaponics (vermiculture, anyone?), this will be a quirky easing in. Workshops in beekeeping or mushroom-growing will allow visitors to try it for themselves. Irwell House, Salford, Manchester (mif.co.uk/event/the-biospheric-project), 5- 21 July.
A blurry cloud of white steel rods, forming a wiry nest in the sky above London's Kensington Gardens: this year's temporary pavilion for the Serpentine Gallery is the work of Japanese architect Sou Fujimoto. A contrast to last year's subterranean grotto by the Swiss architects Herzog & de Meuron and the Chinese artist Ai Weiwei, this promises to be a vision of air and light that gently dissolves into the park. Serpentine Gallery, Kensington Gardens, London W2 (serpentinegallery.org), 8 June to 20 October.
Richard Rogers: Inside Out
Hero of hi-tech, pall of politicians and maestro of our "urban renaissance", Richard Rogers celebrates his 80th birthday with this retrospective at the Royal Academy. It will examine his influence on public policy for more than half a century, but also put personal items on show – such as his collection of his mother's pottery. A "public living room" will include a soapbox for visitors and guest speakers, allowing them to rant and rave about the future of the city. Burlington Gardens, Royal Academy, London (royalacademy.org.uk), 18 July to 13 October.
