The practice will be joined by fellow victors JM Architects, Proctor and Matthews Architects, S333 Architecture and Urbanism Ltd, Sarah Wiggleworth Architects, and Space Craft Architects.
Among the those that missed out were Sergison Bates, and Scandinavian firm White Arkitekter AB.
The competition pitted a 12-strong shortlist of practices against each other to deliver 60 new homes in four terraces around a central park.
The project will form the first phase of wider £400 million proposals to build nearly 2,000 homes on the site west of the city centre.
More than 140 practices submitted entries to the contest, which is run by the RIBA's Competitions Office and has the backing of Newcastle City Council, Bridging NewcastleGateshead and English Partnerships.
Jury member Wayne Hemingway said: ‘The six winning practices are very fortunate. Being able to deliver much needed new thinking in housing is an opportunity to bring real benefit to the Scotswood and wider communities.
But the hard work starts now and the challenges in bringing designs to fruition will be difficult but not insurmountable. I am looking forward to seeing the results’.
