Viviana Pozzoli, co-founder of Equipo de Arquitectura based in Paraguay, has been declared the winner of the Moira Gemmill Prize for Emerging Architecture, while Loreta Castro Reguera, co-founder of Taller Capital based in Mexico, has been highly commended, and Kirsten Gabriëls Webb of Sergison Bates has won the MJ Long Prize for Excellence in Practice.
Moira Gemmill Prize for Emerging Architecture 2023
The work of this year’s winner, Viviana Pozzoli, navigates the social, ecological and economic challenges of the context in which Equipo de Arquitectura practises, to create buildings rooted in their place. The studio, founded by Pozzoli and Horacio Cherniavsky in 2017, is particularly interested in the use of raw earth as construction material, as shown in the early childhood centre in Villeta and the Intermediate House in Asunción.
The Moira Gemmill Prize for Emerging Architecture, named after the director of design at the V&A and latterly director of capital programmes at the Royal Collection Trust who died suddenly in 2015, recognises a bright future for designers under the age of 45 who are leading their own practices.

‘There is something very true and honest about the work Pozzoli is making,’ the judges noted, ‘responding to the local climate and context, and with an impressive emphasis on daylight and air.’ They celebrated that the technologies that the practice is developing can be used by local communities without their input. ‘It is a complete architecture,’ they concluded, ‘encompassing ecology, materiality and research.’
Pozzoli is joined by Loreta Castro Reguera, who was highly commended by the judges. Founded by Castro Reguera and Pablo Ambrosi in 2010, Taller Capital’s public work is informed by Castro Reguera’s research into Mexico’s water systems. The practice has a growing portfolio of public space projects, including Parque Xicoténcatl in Tijuana and Parque Bicentenario in Ecatepec on the periphery of Mexico City.

The judges acknowledged that ‘water is a huge challenge in all parts of the world’, and that Castro Reguera ‘has combined water systems with their social agenda’. They commented that ‘a mix of architecture, advocacy and community engagement has resulted in a substantial and research-driven body of work.’ Taller Capital ‘utilise radical pragmatism to create useful resources for local people, which takes enormous courage.’
MJ Long Prize for Excellence in Practice 2023
Kirsten Gabriëls Webb, associate at Sergison Bates, has been awarded this year’s prize for her work on De Korenbloem sheltered housing in Kortrijk, Belgium. The project for a care home for residents with young onset dementia includes the restoration of an art-deco villa, as well as the construction of a new building which includes residential units. The building primarily attends to the experiences and well-being of its residents.
The MJ Long Prize for Excellence in Practice – named in memory of inspirational architect MJ Long – awards an architect excelling in practice in the United Kingdom.

The judging panel commended the way that De Korenbloem ‘stitches residents’ lives back into the town’, adding that ‘it is an architecture that brokers new territory, casting aside preconceptions in the process of the design.’ They commented that: ‘“architecture can save lives” is one of those phrases you hear bandied about and is usually complete rubbish but here it really has.’ Gabriëls Webb’s work ‘challenges our expectations of what built architecture can be and the process by which we achieve it: there is something so important in the work she is doing.’
