You don’t need to go to the seaside this summer (well, unless you want to of course) because it’s coming to you. Walthamstow is becoming ‘Walthamstow-on-Sea’ until September as Big Penny Social is transforming its terrace into a British seaside resort. Kitted out with deckchairs, sand pits and private beach huts, the pop-up beach is open on weekends for Londoners to soak up the sun with classic fish & chips, soft-serve ice cream, draught beers and frozen cocktails.
