Allie has delivered many of nimtim’s most recognised and celebrated projects including Cork House, Hutch House and Pitch Perfect.
‘Prior to joining nimtim, Allie worked for a Dutch-based practice Play the City in creating games as a method for collaborative urban design - using gaming as a playful way to bring top-down decision makers together with bottom-up members of society.
In 2013 Allie worked in Berlin on small to medium-sized residential refurbishments and extensions - understanding the richness and sensibilities of the existing city fabric.’
Apart from her interest in architecture Allie is interested in many forms of art and design including pottery, surface/textile design and photography – she has recently developed her first reel of film after her trip to Iran.
Fatima
Fatima is a Part II Architectural Assistant, having completed her Bachelors in Architecture at Westminster University followed by her Masters at Kingston University, graduating in 2025.
Throughout her masters, Fatima’s project thesis focused on addressing arising challenges associated with the risk of fluvial and surface water flooding on local high streets and exploring how this can revive the declining pattern of the High Street’s footfall, following its recent decline due to the rise of online shopping methods. The project explores how a series of simple public realm interventions, inspired by the architectural practices of the past, coupled with modern research methods, can rejuvenate the high street and bring the essence of community back to our everyday lives.
Prior to joining nimtim, Fatima spent 4 years working in London for a number of different architecture practices, exploring sectors on a series of different scales, ranging from public realm and community to more private residential homes, where she developed a sensitivity to the personal and intimate nature of home environments.
Outside of architecture, Fatima enjoys riding horses, visiting art galleries and every once in a while, picking up the pencil to draw some portraits.
