Camden approves Avanti, Duggan Morris & Mæ's Holborn proposals

  • Comment

Camden Council has given the go-ahead for the £20 million revamp of the Tybalds Estate in Holborn, London

The scheme, which has been drawn up by Avanti Architects, Duggan Morris Architects and Mæ Architects, includes 93 new homes and the refurb of some of the existing 360 properties dating from the 1950s and 1960s.

The new ‘family housing’ will be built on underused plots around the 2.3ha estate next to the Great Ormond Street Hospital. There will also be ‘side, rooftop and underbuild’ extensions to the surviving blocks.

Tibbalds Planning and Urban Design and landscape architect Camlins are also working on the project which includes ‘significant’ improvements to the public realm and a 12 per cent increase in the amount of useable open space.

The proposals will be delivered in four phases and will take around five years to complete. No homes on the estate will be demolished.


  • 93 new homes in new buildings, and side, rooftop and underbuild extensions to existing blocks. 68 will be affordable homes.
  • Significantly improving the public realm, landscape and open spaces within and around the estate, including new courtyards and new granite paved urban square. The amount of useable open space will be increased by around 12 per cent.
