Sarah and the family begin a new series by creating a traditional country house library, inspired by an 18th-century stately home she previously worked on. It will be covered from wall-to-wall in bespoke bookcases, with sustainable timber coloured to give it a rich, aged, antique appearance, and with another reading area to house more books - a cosy book nook on the landing. Graham installs the library's best kept secret - a hidden drinks cabinet.
