High-end conversion of a former commercial property in Kingston-upon-Thames

  • Project location: Kingston-upon-Thames
  • Project type: Conversion of a former commercial building to create six luxury apartments
  • Property value: Average apartment value £560,000
  • Total UFH area: 555.3m2
  • Developer: Zibi & Jack
  • Project schedule: March – November 2016

Project brief

Nu-Heat were tasked with the design and supply of a bespoke underfloor heating (UFH) system for the conversion of Sutherland House, a former commercial building in Kingston-upon-Thames. The property has undergone extensive conversion to create six, centrally located, luxury apartments. The apartments are situated within walking distance of Norbiton mainline railway station, providing direct access to London Waterloo.

Increased insulation levels in the property had already raised the previous floor level, so it was imperative that the UFH was low-profile, whilst also providing a reduction in airborne and impact noise between apartments.
