Whilst at University, Rosie was sponsored by the Ford Motor Company and received manufacturing, R&D and sales work experience. After graduating in 2002, she joined Max Fordham LLP where she became a valued member of Mark Skelly’s team, and in 2006 was promoted to Partner. Rosie left Max Fordham LLP in April 2007 to work for a charitable organisation in Guatemala, building basic concrete block and tin houses for low-income communities. She began employment with the newly-formed Skelly & Couch in December 2007 as a Project Engineer.

In 2008, Rosie won the Royal Academy of Engineering Sir George Macfarlane Award for demonstrating excellence in the early stages of her career. She has since been promoted to the role of Associate and represents Skelly & Couch in the North East.

Among Rosie's current projects is the environmental engineering design of a new National Trust marine conservation hub based at the Whitburn Coastal Park in Sunderland. It is a prototype led by a new sustainability matrix being rolled out by the National Trust on other developments. She is also contributing to phased refurbishment projects at the Baltic Centre for Contemporary Arts, located on the banks of the River Tyne. 

Rosie has been working on Malmo Quay, a multi-storey residential and commercial facility on a prominent Newcastle site, which will provide a mixed-use, community-centric scheme; the Housing Innovation & Construction Skills Academy for Sunderland College, as part of the regeneration of Sunderland Riverside masterplan where the goal is to optimise sustainability credentials in workshops and classroom spaces for young adults; plus a series of projects and a low carbon masterplan at the Matfen Hall Hotel, Spa and Golf Estate; a foyer heating upgrade at Theatre Royal Newcastle, connecting to existing services; and the Wedding and Conference pavilion and associated accommodation at Walwick Hall Hotel in the Hadrian’s Wall buffer zone, representing an off-grid install to a site with no utility connections and extensive external lighting.

She recently contributed to a new world-class convening hub for Rhodes House, located in a listed heritage site in Oxford; the refurbishment of the Grade II*-listed Hall for Cornwall Theatre in Truro; the world-class School of Science and Sport at Brighton College; and an infrastructure services and energy masterplan at RHS Garden Wisley, providing energy modelling, environmental design and analysis. This followed Skelly & Couch’s work on the £35 million RHS Hilltop building, a ground-breaking centre for science and learning. 

Rosie’s past projects include the 2014 RIBA London Award-winning Arts Centre at the Lady Eleanor Holles School; an extensive refurbishment of Richmond Adult Community College, which created a new studio theatre; the 2019 RIBA National Award-winning Peter Hall performing arts centre at The Perse School, Cambridge; the redevelopment design for the iconic Modernist St Peter’s RC Seminary in Cardross, Scotland; the acclaimed 900-seat Bridge Theatre at Tower Bridge; the spectacular new home of the Mountview Academy of Theatre Arts in Peckham, south London; and the new creative studios at Newcastle's Life Science Centre.
