The consequences of global warming and the UK’s commitments to achieving targets for the reduction of greenhouse gas emissions is increasing the urgency for the UK to move towards a more sustainable future. One aspect of this is to improve the sustainability of the existing housing stock. Our housing stock as a whole is ageing because current demolition and new-build rates cannot meet everincreasing demand. It is estimated that 800,000 people reside in 4000 high-rise tower blocks. Refurbishment of these existing buildings needs to be a high priority. PBA have been commissioned to provide Structural, Mechanical and Electrical consultancy services in support of Sandwell Metropolitan Borough Council, West Midlands in their refurbishment of 44 tower blocks to ‘Decent Homes Standard’. This paper will aim to examine the sustainable value of refurbishment by assessing a ‘typical’ case study and reviewing the environmental and economic impact when compared to new-build.
