External Upgrade to Tenemental Blocks, Lambhill, Glasgow

Value £2,000,000
Term Jan 2009 - Mar 2010


Working with Cadder Housing Association, A.C. Whyte & Co. Ltd was employed as Main Contractor for the refurbishment of some 200 flats, contained within 25 four-storey tenemental blocks. The area of Cadder was originally developed to provide low cost local authority housing. The properties themselves were reaching their life expectancy and required remedial works to comply with the Scottish Housing Quality Standards. The construction of the blocks is Wimpey No-Fines concrete block, which is typical of the area and these were mass produced during the post-second world war era. The regeneration works carried out brought the dwellings up to a modern standard of living. Through time the tenants will benefit from improved health conditions and a reduction in fuel bills.

Good planning of project prior to start on site and were able to recommend savings on the project and pass them on to the client.  Kevin McAllan, Cadder Housing Association
