Transport House is a modernist office building built for the Amalgamated Transport & General Workers Union. The building was designed in the ‘International Style’ by J.J. Brennan. The building is of frame construction and comprises two co-joined blocks, one five stories and the other seven stories. The building is mostly clad in green faience and includes a distinctive tiled mural facing onto High Street. The mural depicts Belfast’s diverse industries and includes an aeroplane, construction cranes, a ship, a public transport bus, and workers in a line.

An inscription near the entrance to the building reads: “This stone was laid on the 25th October 1958 by Frank Cousins Esq. General Secretary of the Amalgamated Transport and General Workers Union in the presence of the Rt. Hon The Lord Mayor of Belfast Alderman Major William Cecil McKee J.P. E.R.D. and Norman Kennedy Esq. Irish Secretary at A.T.&G.W.U. and a distinguished gathering of civic and union representatives / Carville & Sons Ltd Contractors / J.J. Brennan & W.R.P. Bowden, Architects & Engineers”.

Transport House was listed in 1994 (Ref: HB26/50/234).

The General Secretary of Unite the Union confirmed plans to refurbish and reopen Transport House in September 2021.
