The Great Big Tiny Design Challenge

G Ten amateur miniature makers must transform a derelict mini mansion into the ultimate fantasy house, starting with a Regency-themed dining room.

G The miniaturists tackle Art Deco design to create miniature toiletries befitting a 1920s bathroom. The winners of this first challenge will lead the next test - building the bathroom itself, running water and all!

M The miniaturists are asked to create a Victorian nursery, which must contain a pram, puppet theatre, rocking horse and the mother of all doll's houses - a replica of the competition's mini mansion itself!

G The miniaturists are asked to create Elizabethan bedroom accessories. The two winners of the individual challenge go on to lead a team to tackle the entire room which must contain a bed, fireplace and writing desk.

G The remaining miniaturists tackle their most ambitious build to date: a two-floored Rococo hallway. The hall must contain a wall mural, console table and chaise longue.

G The five remaining miniaturists tackle an Edwardian games room, which must contain a billiard table, display cabinet and, for the team with the extra person, an indoor plant.

G It's the semi-final and the four remaining miniaturists create a Georgian kitchen complete with a full range, mangle and an array of accessories and items to fit in a dresser.

G Grand Final: The two remaining miniaturists create a statement period piece before designing their dream room for the mini mansion.
