Portobello Square – the regeneration of Wornington Green

Our Portobello Square regeneration project at the Wornington Green estate in Kensington will deliver approximately 1000 mixed tenure new homes for social rent, private sale, and shared ownership.


Wornington Green Estate is owned and managed by Catalyst. The estate originally comprised 538 flats and houses (accommodating approximately 1,700 residents) which were constructed between 1964 and 1985 in predominantly large deck-blocks, typical of public housing of the period.

The estate in its original form had, over several decades, undergone exponential changes in an attempt to address problems arising from both its design and construction methodology; but these had failed to resolve inherent problems with access, security, poor design and layout of homes. The 2006 options appraisal concluded that the complete redevelopment of the estate was the only realistic option to ensure the delivery of better housing for residents.

Our video tells the story of how we recreated the original street pattern for Bonchurch Road as part of the project.

Our plans

Portobello Rd_in page imageOver 10 years Catalyst is regenerating and remodelling the estate creating a sustainable, mixed tenure community. Portobello Square will be built in three phases delivering approximately 1,000 new homes.

  • No loss of social housing. All current tenants will be offered new homes in the development
  • New homes for private sale and shared ownership
  • Social housing is seamlessly integrated with the private to create a truly tenure blind development
  • Creation of shops and community facilities and improved public realm
  • Reintegrating the new neighbourhood into the surrounding street pattern
  • Re-providing the existing council-owned park in the heart of the new neighbourhood

Phase One includes the building of 324 new homes, a mix of 174 for affordable rent and 150 homes for private sale. Work on Phase One started in 2012 and is scheduled for completion in May 2016.

Phase Two was granted planning permission in July 2014 and is due to start on site in early 2017.

Paul House provides space for community projects

Catalyst will be using the premises at Paul House, Ladbroke Grove, as the base for a range of projects that support and empower the local community until the time comes to demolish it.

This will provide more services and opportunities for local residents delivered by our Catalyst Gateway Team. Support for children, young people and families and access to financial inclusion services and help to find employment can now be provided from this refurbished space at Wornington Green. It may also be used as a meeting place for residents once the current residents’ room is demolished.

Latest news


In the past month:


  • The first core of Hardy Mansions was handed over before Christmas, and owners are moving into their new apartments. The second core has also been handed over and tenants have started to move into their new homes. The townhouses and remaining private and rented apartments will be completed towards the end of March.


  • Demolition of Pepler House, Edward Kennedy House and 192/194 Wornington Road is ongoing, with 192/194 Wornington Road now completely demolished.


  • Works have now started to the park, clearing and grassing the larger area ready to be handed back to the council. The existing hoarding in the park has been removed and a new hoarding put in front of the temporary haul road. The footpath through the park has been slightly adjusted to accommodate the hoarding and allow us to increase the size of the temporary park when Phase 1 is complete.


  • We received tenders for the construction of Phase 2a on 23 January. Two contractors went forward to tender interviews on 6 February, with two members of the Residents’ Steering Group on the panel. We expect to announce the successful contractor in April.


  • A design competition to select the architect for Phase 3 is underway. The residents will be represented in the final selection panel over the coming months, and we expect to announce a selection in May.


In the next month:

  • RBCK have been doing some works by the haul road on Wornington Road. This was emergency work to fix pooling of water on Watts House car park. Whilst temporarily inconvenient, it will fix a long-standing problem of interest to residents, and will be finished by the end of the week


  • Moves into Hardy Mansions will continue over the next few months.


  • Over the next few weeks, the Royal Borough of Kensington and Chelsea will complete some pavement works and crossovers on the new roads, which are otherwise complete. Faraday and Bonchurch roads will be opened up to full use in the next couple of months as the council take them into management.
