Sophie is a Senior Architect at our London Studio, currently working on multiple major planning applications around the UK. Since joining JTP in 2017, Sophie has worked on a variety of high and low density projects in both urban and rural settings. Her projects range from the award-winning Fulham Reach, a riverside urban masterplan of 750 homes and mixed-uses in West London, to Knowle Park – a countryside neighbourhood of bespoke homes in rural Surrey. 

Her current role involves leading teams on high-density regeneration projects, focusing on collaboration, innovative design and sustainability to unlock each site’s full potential. Passionate about social mobility, Sophie has delivered multiple exemplar affordable housing and community-led urban regenerations, including Devonshire Place, London and Blackbird Leys, Oxford which both received unanimous planning approval in 2023. Acting as Lead Project Architect on Blackbird Leys, the regeneration involves a high-density social housing scheme that provides 294 affordable, low-energy homes within infill sites. Alongside housing, the proposals include a new Community Centre, retail spaces, a public square, public green spaces and extensive public realm improvements. The proposals were developed with continuous and active engagement spanning years where local people were invited to shape the proposals every step of the way. 

In her first two years as a qualified Architect, Sophie has helped to secure planning applications for over 750 affordable homes, providing affordable housing for more than 2,500 people. She strives to create places that improve people’s quality of life ensuring that her work is marked by a commitment to create exemplary places to live for all. 

In 2023 Sophie was crowned as one of Property Week’s RESi Trailblazer Winners, which celebrates the brightest talents and emerging stars in the UK property market. 

Alongside projects, she is actively involved in the organisation and delivery of a number of social value initiatives at JTP, including recruitment, mentoring, and portfolio and interview support with the charity Blueprint for All.  She hopes to empower those who may not have had access to the resources, guidance and support they need to thrive. She also leads and co-chairs JTP’s inaugural Health and Wellbeing Group, responsible for instilling measurable health and wellbeing deliverables into our projects – helping us to design healthier, more sustainable, and enriching places. She also sits on the Board of the Young Architect’s and Developer’s Alliance (YADA).

Our people are the heart of who we are.
