  • I am an Architectural Designer and Project Manager with over eight years of experience delivering residential and commercial projects across London and the South East. My background covers architectural design, interior design, construction management, and large‑scale fit‑out projects, giving me both creative design expertise and strong practical knowledge of how buildings are constructed. I work across London, Greater London, Berkshire, Surrey, and nearby areas, and I also take on remote design projects nationwide. For clients who cannot accommodate site visits, I provide clear guidance on measurements, photos, and information needed so the project can run smoothly from start to finish. My specialist skills include planning drawings, building regulation packages, technical details, 3D visuals, and full construction documentation for extensions, loft conversions, refurbishments, and new builds. I’ve managed projects from £20k to £2m, coordinating with engineers, contractors, and homeowners to ensure designs are accurate, compliant, and buildable. Clients value my clear communication, attention to detail, and commitment to quality. I deliver practical, well‑thought‑out designs and a smooth experience on‑site or remotely.
