The young architects changing the face of Britain

Cineroleum was a cinema which ran for fifteen evenings only, the maximum number permitted by its temporary planning permission. It was built in a disused petrol station for very little money, in very little time, with the help of enthusiastic student labour. At the end of each screening the curtain surrounding the seating would rise, such that the audience would suddenly find themselves sitting in the street Photograph: Lewis Jones/PR

Feilden Fowles’ Ty Pren, a new house in the Brecon Beacons, Wales, aims to emit almost no carbon. It uses materials found within a two-mile radius of the site, including re-used slates and larch grown nearby, and is oriented to make the most of warmth from the sun. Its form and materials echo traditional houses in the area, but have a contemporary sharpness of detail Photograph: David Grandorge/PR

Studio Weave’s “Longest Bench” in Littlehampton, Sussex, can seat 300 people. Its architects call it a “charm bracelet” and it twists around existing features such as walls and lampposts. It is made of hardwood recycled from sources including sea-defence groynes. The project includes shelters, where the bench forms loops within a bronze-finished enclosure Photograph: Valerie Bennett/PR

Franks Café and Campari Bar has been built on the top of a multi-storey car park in Peckham, south London, for the last two summers. It offers penthouse panoramas of London from a structure built of scaffolding boards, and of the kind of canvas you more usually see on the side of trucks. It has been hugely successful and fashionable, to the extent that its designers, Practice Architecture, are worried that they have become unwitting gentrifiers of the neighbourhood Photograph: PR

HAT’s Jerwood Gallery in Hastings, due to open later this year, is in a sensitive location among the town’s unique “net houses” – black wooden towers built to serve the fishing fleet. The gallery’s dark ceramic cladding is designed to complement but not mimic the towers Photograph: Hat Projects/PR

The gallery's interior is simple, so as not to overwhelm the art on show, with windows giving selected views onto the surrounding town Photograph: Bentley Systems, Inc./Hat Projects
