Introduction

Warwick House is a refurbishment and new build project comprising 18 council flats. The existing flat block was cut in half, the remaining half was refurbished and a building in a different configuration provides the other half. 

Description

Successful waste minimisation was a result of the London Borough of Lambeth client commitment to sustainable construction. In addition to waste minimisation, the project incorporated rainwater harvesting and solar panels. Specific solutions implemented to secure waste minimisation included: 

Construction best practice 

  • demolition waste was mostly composed of brick and concrete, which was crushed and taken to a nearby site to store until required for reuse in foundations, road sub-base and crane base 
  • reclaimed concrete roof tiles from the demolished section were used to repair the refurbished section of roof 
  • the BRE SMARTWasteTM tool was used to monitor site waste and identify waste streams and methods for dealing with them. Bins for timber, plastics and metals were located on site for waste separation

Design/specification

  • materials with a high percentage of recycled content were also specified; including boards made from timber waste and forest thinnings, plasterboard with a high recycled content percentage, and prefabricated timber panels with recycled newspaper cellulose insulation 
  • offsite manufacturing was used, e.g. timber frame and concrete floors 

Not all crushed aggregates were returned to site, the remainder was set aside for use elsewhere in the Angell Town area.

To ensure the smooth flow of recycled aggregates between this and other projects, the same demolition contractor was used for other works in Angell town.

Together with other sustainability solutions, waste minimisation and recycling led Warwick House to be a flagship development.
