Rydon is undertaking an innovative cross subsidy redevelopment to regenerate a large failing local authority estate within the London Borough of Sutton.

As developer and contractor partner to Affinity Sutton and the London Borough of Sutton, Rydon is delivering the decant and demolition of around 300 local authority properties at the Durand Estate and the development of 260 homes for open market sale and 214 new affordable homes. A further 18 of those homes developed for open market sale are to be used in the Private Rented Sector.

Durand’s redevelopment is being delivered across four phases over a period of eight years. The proposals gained an 82% approval rate from the residents, following design and strategy meetings between the partnership members.

Phase 2 recently completed, the largest of the phases to be constructed so far. This provided a total of 116 flats, a mixture of open market sale and affordable, all constructed to Code for Sustainable Homes Level 4.

Work to Phase 3 is now underway and in addition to the new residential units, this phase includes a new park, play areas and upgrades to the banks of the river Wandle, which runs parallel to the site.

The environment is always an issue of paramount consideration on Rydon projects and this led the project team to look at ways to cut the scheme’s carbon footprint. 14,000 tons of crushed concrete from the demolition of Phase 2 has been recycled into the new foundations using vibro stone columns. This technology compacts the surrounding soil, removing the need to dispose of spoil at landfill and saving an estimated 1,340 lorry movements.

This innovative working has attracted the attention of national awards and the project was awarded a Green Apple Gold Urban Landscape Honour.

As part of Rydon’s partnership with Affinity Sutton, the London Borough of Sutton included a package of 10 associated sites to assist in the regeneration aims. These range from seven to 120 homes and provide an additional 171 affordable and 96 open market sale homes across the project. Nine of the associated sites are complete providing 150 affordable homes, for decant and new residents alike, together with 71 open market sale homes providing cross subsidy.

As developer, Rydon has maintained the scheme’s viability across the different sites and has achieved this by adjusting tenure and unit mixes as well as seeing and securing new funding streams. Rydon has developed its relationship with the borough planners and members on each planning application, allowing planning to be secured in the most challenging sites where neighbouring resident opposition has proved difficult.
