John Schofield and Lisa McCormack left their corporate jobs "and emptied their money boxes to fulfil a dream of creating a place of beauty - a garden centre but like no other".
Battersea Flower Station was created with help from local builders and a Battersea Arts Centre set designer. It features free local delivery, window box planting, garden and balcony consultations and personalised vouchers.
The centre has a resident plant and garden expert as well as a florist. Its shop, which is in a tin shed, offers soap, candles, seeds, "living postcards", pots and kitchenware, all sourced from within London. All plants, trees and garden goods are sourced as locally as possible.
