Redevelopment of Dollis Valley estate due to restart in September after three-year delay in demolishing vacant flats

Completion of the redevelopment of the Dollis Valley estate – where blocks of flats and maisonettes have been awaiting demolition for the last three years – is finally to go ahead with access to a £58 million grant from the Greater London Authority.

Regeneration of the estate was stalled in 2023 because the developers Vistry said the scheme previously agreed with Barnet Council for 126 new privately-owned and 95 affordable homes was no longer viable.

A revised plan approved at a cabinet meeting will now provide for the construction of 208 affordable homes which will be managed for the council by Barnet Homes.

The new Dollis Valley houses – 187 for social rent and 21 for key workers – will provide what is described as a “significant” contribution to Barnet’s target to deliver 1,000 new council homes.

But by abandoning the previously agreed construction of over 100 new private homes, the council has angered owners of new Dollis Valley houses who fear this will alter the balance of an estate which was supposed to be a 50/50 split between private and social ownership.

Despite what was described at the meeting as the “potential guilt” felt by some councillors for letting down the private owners, the cabinet decided there was no other viable option than to accept Vistry’s latest proposal.

To qualify for access to £58.85 million of GLA affordable housing grant, construction of the new houses has to start by September this year.

If the council failed to meet the deadline one option would be to demolish the vacant flats and maisonettes and retain the empty site until the housing market improved but that would expose the council to further financial risk.

The first three phases of the Dollis Valley regeneration have delivered over 400 new houses in what the council describes as “a low-rise, gentle density garden suburb style development dominated by houses with gardens and traditional streets.”

The final two phases of the scheme – which would result in the demolition of the vacant Garrowsfield and Mill Bridge blocks – were originally intended to provide 126 private and 95 affordable homes.

Poor market conditions and increased construction costs were said to have made this “significantly unviable” which resulted in Vistry proposing the construction of 208 affordable homes at “a fixed price” and 13 private homes, the scheme which has now been approved.
