One of the two remaining Baron Grove Houses – the other being 470/472 London Road.
Grade II listed by Historic England, who describe it as:
Semi-detached pair of houses. Early C19. Brick; channelled stucco to ground floor. Slated mansard to lower outer bays; roof not visible to inner bays. Mainly 3 storeys plus basement. Each house 3 windows wide. The outer of only 2 storeys and recessed, with entrances on returns. Square gauged headed windows, sashes, glazing bars. Margin glazing to ground floor. Cornice above first floor to entrance wings and above second to centre part. Later C20 1 window extension to left of No 484, not included in listing.
Up to 1973 number 484 was occupied by the Labour Party, and it and 482 were bought by the Latter Day Saints who wanted to demolish them and build a church. Merton Council refused but did allow the church to be built at the rear. The council also allowed the chimneys to be removed. Hence the other Baron Grove house at 470/472 still have them.
