With Britain bursting at the seams with one-of-a-kind holiday stays for every budget, Channel 4 is sending Sandi on a journey of Extraordinary Escapes. Accompanied by some of the very best names from her little black book of travel companions, namely acting royalty Alison Steadman, funny woman Sindhu Vee, comic actress Jessica Hynes, and close friend and foodie Prue Leith, Sandi will explore the delights of the UK's wildest, most remote and beautifully designed holiday digs. Whether a lofty lighthouse or a towering tree house, the ingenious builds in each episode will appreciate the architecturally inspiring, cleverly designed holiday properties Britain has to offer and show viewers that stay-cations are something to be celebrated. From secret retreats and seaside sanctuaries to quirky windmills, the pair will uncover the fascinating design stories behind each property. They'll marvel at the incredible lengths the owners and architects have gone to, to ensure each property offers a unique experience, from brave and bold designs that make the most of a stunning view to passion projects where every detail has been considered to homes that embody the sense of wonder found in their surrounds. Sandi and her travel pal will also immerse themselves in the natural beauty of each location to make the most of their time away, indulging in wildlife spotting, picnicking on the beach, forest-bathing, cooking local produce and sharing stories as the sun goes down. They'll reflect on the important things in life - from family, health and careers to exploring the meaning of solitude; as well as sharing lots of laughs and appreciating the privilege of being given the keys to these extraordinary escapes.
