Opened in May 1977, it is the headquarters of Kensington and Chelsea London Borough Council.

[1] After both the old town halls had been rejected as inadequate for the council's needs, civic leaders decided to procure a new facility; the site selected for new building in Hornton Street had previously been occupied by two large residential properties: Niddry Lodge and the Red House.

[10] An ornamental pool which had been created beneath the council chamber was converted into a small garden planted in memory of Princess Alice, Countess of Athlone and was opened by the Duke of Gloucester on 4 May 1983.

[5] The design for the main frontage on Hornton Street features glass doors on the left of that elevation which give access to the civic suite on the ground floor; there are tall oriel windows on the first floor which are cantilevered over the pavement.

[9] Works of art in the mayor's parlour include a portrait of the collector Sir Hans Sloane, by Thomas Murray.
