Porters Annex was a two storey red brick building that had a flat roof extension at the rear and an area of 0.077ha. The building was used by the Belfast School of Music but was later declared as surplus by the Belfast Education Library Board (BELB).

Prior to disposal to the private sector, expressions of interest were sought by Land & Property Services (LPS) from public sector bodies who may be interested in acquiring the premises. An indicative value of £160,000 has been placed on the Porter’s Annex building by Land & Property Services (LPS). Music Hall Services Ltd then acquired the site for around £140,000 at Lambert Smith Hampton’s auction in 2016.
