Based in the heart of Truro, Lilly Lewarne Architects undertake a variety of projects throughout the entire south of England.

Our Aim

Our aim is always to strive for excellence in design, and to provide a sensitive yet professional service which fully meets the needs of all our clients. As with our ever changing society we constantly find the need to adapt, revise and reconceive the architectural language we employ.

We design with site, time, materiality, sustainability and humanity in mind to enable us to create an architecture that is appropriate and not just wilful. We endeavour to employ a sense of clarity to our projects to handover to the client a building they can be proud of and promote as a positive part of their business or as an extension of their character.

By employing the latest technology in association with traditional hand drawing techniques Lilly Lewarne Architects are able to provide a fully comprehensive service – ranging from the early stages of feasibility designs and planning negotiations through to the preparation of production/construction drawings and ‘on site’ inspections, and where required the integration of internal design and fitting-out elements.

Client Testimonials

“Lilly Lewarne not only showed their own passion but believed in ours, guiding us through the technical minefields whilst remaining committed to the brief we had set them.”

Mr & Mrs J Dukes

“Lilly Lewarne have proven to be highly professional in dealing with a complex planning, design and construction project; faced with often unexpected challenges, the team have always reacted quickly and effectively, proposing and implementing change where needed. It has been a pleasure to work with James and his team, and I would not hesitate to recommend them to other owners.”

Mr & Mrs Robson

“Thank you Mark, we are obviously delighted with this outcome and may I immediately acknowledge the hard work that you, James and the team have put in to enable us to reach this point. Your guidance and assistance to navigate the Planning Process was undoubtedly the key to a favourable decision and we are very grateful for this.”

Mr & Mrs Jane

“I write to congratulate and thank you all for what has turned out to be a fine example of the building industry in the South West, indeed “ at its best”.

From the outset of the project i.e. my initial meeting with James Moran (Lilly Lewarne Architects) to the handling of a very minimal snag list, my observations have been overawed by the attention to detail and quality. As an owner being stranded some 250 miles away with the Covid element restricting travel and contact I had to be resigned to complete reliance on the ability of you all to produce the end result. As a team you covered all aspects of the operation with a professional attitude and attention to detail – the finished article says it all. As things progressed I was always kept informed and involved to ensure that I would be happy with even the slightest change or choice that was required, sometimes on a daily basis.”
