A five-storey office building built 1957-58 for the Inland Revenue. The building was designed by Morris de Metz and was officially opened by Terence O’Neil, then Minister of Finance, on 15 May 1958 (a plaque at the building entrance marks this occasion). The building was named ‘Olive Tree House’ since its opening in 1958 until 2014 when Concentrix opened offices in the building and changed the name to ‘Concentrix House’.

The building was placed on the market in November 2014 by Frazer Kidd, on behalf of Alterity Investments, inviting offers over £1.75m. It was reported in May 2015 that the building was sold for £1.95m.
