In south London, Kirstie Allsopp and Phil Spencer search for a flat for first-time buyers Adam and Nicole, and a townhouse for world-record-holding rower Kat. Adam and Nicole live with their respective parents and need help to get them living together under the same roof but their home patch has become a pricey part of town, so they've saved for their entire adult lives to get a large enough deposit. They're nervous about spending all that hard-saved cash, but Kirstie manages to find them some hard-to-resist homes. In 2019 Kat was diagnosed with cancer. After going through chemotherapy and being told she was in remission she wanted a new focus, so she joined an all-female trio for an Atlantic rowing challenge. They beat the previous world record by more than seven days, and Kat's next challenge is to put down roots with a townhouse in her beloved south London. Even with a budget of over a million pounds, Phil finds it tough to hit everything on her wishlist in the top spots where she wants to live but once they manage to focus her search on Greenwich, things start to fall into place. A house with potential tugs at Kat's heart.
