What Sims Hilditch does

Sims Hilditch is a privately held, founder-led British luxury interior design studio established in 2009 by Emma Sims-Hilditch, headquartered in the Cotswolds with a London office. The firm delivers full-service interior architecture, design, and procurement for high-net-worth private clients, with a secondary practice in luxury hospitality and developer-led residential projects, including Calcot Manor and The OWO Residences in London. The studio employs more than 30 designers and is supported by a back-office covering project management, FF&E, procurement, marketing, and workplace functions, indicating a deliberate move from founder-led craft to professionally managed design practice following the 2025 appointment of CEO Henry Hird.

The business model is project-based, fee-driven bespoke design: each engagement is a multi-year, multi-disciplinary mandate covering concept, architecture, sourcing, and installation, with project values in the high six to seven figures (a single OWO Residences unit was disclosed at £14.5m, implying substantial contract economics per mandate). Revenue is generated primarily through design fees and procurement mark-ups on FF&E, with supplementary income from a small portfolio of named product collaborations with heritage manufacturers (Marlborough Tiles, George Smith, Chelsea Textiles, Tim Page Carpets) and royalties or sales from two published books. The firm pursues no external funding, has achieved B Corp certification in 2025, and was named a Sunday Times Best Places to Work 2025, signalling professionalisation rather than venture-style scaling.

Commercially, Sims Hilditch competes on brand, editorial visibility, and senior-talent quality rather than on price or technology. Distribution is principally earned media — features in House & Garden, Vogue, and The World of Interiors — supplemented by participation in flagship showhouse events such as WOW!house 2025 at Design Centre Chelsea Harbour. International mandates in the Netherlands and the United States indicate the early stages of geographic expansion beyond the UK domestic base, executed without disclosed local offices. The combination of HNW private work, hospitality, and developer-led residential gives the firm a diversified but inherently concentrated client base, given the high value and discretionary nature of each project.
