Double Your House for Half the Money

In Elstree, Hertfordshire, Sarah Beeny meets Oliver and Lucie Herman, whose £900,000 property once doubled as a dentist's surgery. The couple have taken on the challenge of transforming the building into a stunning new home with a whopping £200,000 to spend. However, the budget still skyrockets out of control. In Liss, Hampshire, Graham and Alana Tourell want to restore a former post office - a stunning arts and crafts period property - into a home. But sourcing original and reclaimed items for the renovation doesn't come cheap and takes months.
