Format Designs

Format Designs is an interior design studio based in Hertfordshire, crafting considered spaces that are as functional as they are beautiful. We believe good design starts with listening. Every project begins with understanding how people truly live, then translating that into interiors that feel personal, timeless, and quietly confident. From initial concept to final styling, we work closely with clients to shape homes that are tailored in every detail—from bespoke joinery to layered finishes, lighting, and materials. As part of the Format Group, we work seamlessly alongside our sister company, Format Build—a construction firm known for its craftsmanship and meticulous attention to detail. This close collaboration means we offer a full turnkey service, managing every aspect of your project from pre-construction design through to final handover. Whether we’re restoring a heritage property or designing a modern extension, our process is hands-on, highly personalised, and led by quality at every stage. ➝ Residential Interiors ➝ Commercial Interiors ➝ Full-Service Interior Design ➝ Design + Build ➝ Renovation & Project Management ➝ Custom Joinery & Detailing
