Redevelopment of Dollis Valley estate to be restarted after two year delay following go ahead for construction of 221 new homes

Completion of the Brook Valley Gardens estate off Mays Lane – which is a regeneration of the Dollis Valley estate – has moved a step closer.

Progress has been stalled since 2023, but a revised deal has been agreed with the developers and approved by Barnet Council.

Demolition of the remaining 1960s high-rise blocks and maisonettes will take place shortly. This will allow work to start on another 221 new homes.

The redevelopment had to be halted when the developers told the council that it was no longer economically viable to build the final 221 new homes on the basis of a split between private and social housing.

To get the regeneration of Dollis Valley back on track, the council’s cabinet has decided that the new homes that are yet to be built will now all be socially rented and under the management of Barnet Homes.

However, the failure to continue – as was originally proposed – with the construction of another 128 houses for private sale, will mean that instead of Brook Valley Gardens being a mixed-tenure neighbourhood the estate will become 60 per cent social housing.

This change has angered many of householders in privately owned homes on the estate who are organising a petition to present to a meeting of the Dollis Valley Partnership board at its annual meeting in March.

They say that Barnet Council has failed to hold any consultations about a fundamental alteration to the terms under which they purchased their houses.

“Barnet Council is bulldozing this through and have been keeping residents in the dark over Brook Valley Gardens becoming 60 per cent social housing.”

Private householders are concerned about the future saleability of their properties because mortgage lenders now take into account the percentage of social v private housing on an estate.

Because the original plan was for 50 per cent private housing, high street banks were happy to lend money on Brook Valley Gardens properties but with 60 per cent social housing future owners might be unable to obtain mortgages without resorting to specialised lenders and this could “materially affect property values for existing homeowners.”  

The remaining Mill Bridge and Garrowsfield blocks of flats and maisonettes in the Dollis Valley estate were surveyed in 2024 and were found to have widespread damp and mould.

They were deemed unsuitable for prolonged occupancy beyond December 2025 and the council decided to rehouse the tenants. Demolition is now to due start in the coming months.

The delay in finishing the estate arose because the joint developers Vistry Group (formerly Countryside Properties) and London and Quadrant declared that the original plans were no longer cost-effective.

Vistry proposed an alternative accelerated programme, and the council cabinet has now agreed to purchase 221 social and affordable rent homes from Vistry at a fixed price, subject to securing grant funding from the Greater London Authority.

On completion, Barnet Homes will manage the properties on behalf of the council. Eleven will be wheelchair accessible.

Vistry is proposing to deliver an accelerated programme of construction of replacement homes so that tenants rehoused from Mill Bridge and Garrowsfield can be prioritised to return on completion if they wish to.
