I’m Jackie Ballhatchet, an Architectural Designer based in Walthamstow and the Isle of Wight. Through Fourfold Design, I work with homeowners on extensions, renovations and garden projects, offering a masterplanning approach that balances creativity, clarity and long-term value.

I hold a Bachelor of Architecture from Cornell University and have over 15 years’ experience working in leading London practices, including KPF and AHMM, where I was working in all RIBA stages on complex, large-scale projects. Alongside this, I continued to design and deliver residential renovations for myself, friends and family.

I founded Fourfold Design in 2025 to bring together my experience managing large projects and teams with my passion for improving everyday life through homes and gardens. I am a licensed architect with the New York State Education Department, a member of AIA UK, and am well-versed in UK planning and building regulations.
