Lucia Piccinini
Project Architect


Understanding both client requirements and regulatory frameworks in order to unlock value through exceptional design

Lucia qualified from the University of Architecture of Florence and started her career in Italy before moving to the UK. Having worked through RIBA stages 1- 7 over the course of more than 10 years in practice, Lucia has grown immeasurably in her ability and proficiency as a talented and highly capable Project Architect. With her technical skills and creativity, she excels in her involvement at all stages of an architectural project from initial concept creation, through technical development and construction, to final handover and post occupancy evaluation.


During her career in both Italy and the UK, she has worked on a diverse range of architectural projects including new-builds and refurbishments of mixed-use premises, high-end urban residential schemes, commercial properties and complex change of use projects. Lucia has a wide breadth of experience in her client base, having delivered projects internationally for real estate investors, private developers, private clients, high-net worth individuals and main contractors. Her responsibilities to these clients have included defining their requirements to deliver solutions on budget, securing planning application approvals and obtaining funding from investors and financial institutions.


Lucia is committed to the values of sustainable construction and has an eye for environmental responsibility. She has an innate passion for artistic expression and architecture’s social impact, creating living and working spaces to the highest of standards.


Creating places and destinations which are informed by their physical, cultural and socio-economic context

Paula's background stems from a Master’s degree in Architecture and Building Engineering, followed by a work experience in architecture and urbanism, collaborating with Steven Chilton Architects & MIRO Architetti on international projects of a variety of scales. Ranging from interior design to façade design, and urban planning research (working with the “Planning & Regeneration” team of the Department of Architecture at the University of Bologna in Italy), she is truly cross-disciplinary. In particular, during her experience in Bologna she was part of the management group of a cross-regional European project focused on boosting low-carbon multi-modal mobility for more sustainable cities.


Paula has also worked on the creation of territorial cognitive frameworks for two Italian Municipalities, which was the basis for the development of their new Urban Plans. This work included a deep study of the social, built, and natural environment, that also considered aspects such as building energy behaviour, land use, and other informative factors, as well as the creation of a GIS model containing all of the data collected.

Paula strongly believes that communication and collaboration are the keys to responding to the needs of a rapidly changing world and to design more liveable, inclusive, and sustainable cities.
