Avondale Drive estate, Hillingdon
144 homes are under threat on Hillingdon's Avondale Drive estate in Hayes (117 Council and 27 leasehold).
The estate consists of three 12 storey point blocks located adjacent to Hitherbourne Park around 1 mile North of Hayes & Hillingdon train station (new crossrail station).
In March 2016, Hillingdon Council applied to the Mayor to establish Hayes Town Centre as a 'Housing Zone'. The application contained a list of potential development sites for new housing (appendix 5). The Avondale Drive estate was listed as one of them along with the Austin Road estate.
Four years later, in 2020, Hillingdon commissioned Savills to undertake an options appraisal study to consider options for the redevelopment of the estate.
The Savills report recommended demolition and rebuild on the basis that the estate has high investment needs, requiring an estimated expenditure of £59,726 (per unit) in maintenance costs over the next 30 years compared to a London average of £30,160.
But the £57,631 figure includes 'additional expenditure' of £11,603 per unit for other works like installing sprinkler systems.
In addition, the Savills report fails to provide any underlying data supporting its claim that the London average estimate is £30,160. Savills' own figures elsewhere contradict this; in 2015 Savills undertook an appraisal of Southwark Council's stock and estimated that it required £55,942 per unit expenditure on average (see para 1.8).
On 22 October 2020, Hillingdon Council resolved to proceed with a residents' ballot on demolition in line with the recommendations of the Savills report.
The ballot was held in March 2021, with 94% in favour of redevelopment on an 85% turnout.
