Episode list

James gets a group of thirteen-year-old children from Telford to build a life-size Airfix model of a Spitfire aircraft, complete with a model of himself as the pilot.

James designs and builds a garden where all the flowers, trees and garden furniture are made of plasticine. He enters it in the Chelsea Flower Show, much to the disdain of the event's organisers.

James builds a combined swing and lifting bridge out of Meccano, to span a canal in Liverpool's dockland so he can walk from one side to the other.

James builds a Scalextric racetrack around the full length of the disused Brooklands racetrack in Surrey. Much of the former racetrack has now been built on, so his track needs to cross an ornamental pond on a pontoon bridge, climb a staircase in an office block via a spiral ramp and run through the streets of a housing estate. He then races two cars around the 3-mile track.

James builds a full-size house out of Lego bricks, complete with internal fittings such as table, bed, toilet - all made of Lego too.

James builds a 10-mile 00-gauge model railway on the trackbed of the disused line from Barnstaple to Bideford in Devon, and then runs model trains along the track, in an attempt to break the world record for the longest model railway.
