Artlab Architects has gained planning and change-of-use permission for a former limeworks in Faversham, Kent.
The focal point of the 1930s water-softening plant is two huge concrete cones, between which is an imposing rendered tower.
Under the scheme, for an unidentified client, Artlab will convert the building into a private dwelling. The client will also carry out the building works.
Project designer Colman Cotter said the trickiest element of the scheme, which involves wrapping the concrete cones with glass, was 'getting the external glazing element approved'.
Cotter added: 'We have left big internal spaces. The left cone will have a rooftop swimming pool, gym and a spiral staircase, the last step of each will stop in a sauna.'by Max Thompson
