Fledgling practices, including Acme, DSDHA and Mae, are rubbing shoulders with Foster + Partners and Grimshaw on the shortlist for a public sector architects framework in London.

The 42-strong list on the Design for London framework is a mix of recently formed practices, established London firms, planning consultants and landscape architects. It is understood that about 20 firms will be selected for the final list in June.

There were more than 180 applications for the framework, which is intended to provide Design for London and the London Development Authority with partners for regeneration and urban design projects over the next three years.

One notable absentee from the list was Rogers Stirk Harbour + Partners, even though Lord Rogers acts as the mayor’s chief adviser on architecture and urbanism.

Established names that have made the cut include Allies and Morrison, Edward Cullinan, Foster + Partners, and Grimshaw. They are listed alongside up-and-coming practices such as Alison Brooks Architects, East and Studio Egret West.
