LESA Bertie
Interior Designer
“Creative ideas are just the beginning—what matters most is turning them into something real.
Clear planning, attention to detail, and keeping momentum are what ensure a design isn’t just imagined, but fully and beautifully delivered.”
Lesa Bertie approaches interior design with clarity, focus, and a strong creative instinct. With a background in retail buying and merchandising, she’s spent years honing her ability to visualise spaces, manage complex details, and make confident, style-led decisions—skills that now underpin her work as a designer.
Having renovated several homes of her own, Lesa understands how to balance ambition with practicality. She trained at the renowned KLC School of Design before transitioning fully into interiors, where her methodical yet imaginative approach helps clients bring order, purpose, and personality into every room.
“There’s something incredibly satisfying about reworking a space to give it meaning again—seeing the spark when a client realises what’s possible. It’s not about trends, it’s about making things work in a way that feels natural and right.”
Based in Streatham, Lesa works with clients across London and the Home Counties.
