The eye-watering average budget was revealed ahead of the Northern Homebuilding & Renovating Show, set to take place from October 30 to November 1 at the Harrogate Convention Centre. Michael Holmes, a property expert at the event, said: "A budget of this size represents one of the largest financial commitments most homeowners will ever make, after buying the property itself. The show will feature more than 250 exhibitors and daily seminars on topics including planning permission and design ideas. Visitors can book 15-minute advice sessions with experts including Mr Holmes, architect Allan Corfield, planner Sally Tagg, and self-build specialist Mark Stevenson. The show runs from 10am to 5pm on October 30 and 31, and from 10am to 4.30pm on November 1.
