Spratley & Partners

What Spratley & Partners does

Spratley & Partners is a UK-based architectural practice founded in 2004 by Jeremy Spratley, now operating as a six-partner equity-owned firm from studios in London, Henley-on-Thames, and Bristol. The practice delivers architectural design, heritage conservation, interior design, and sustainability services across six sectors: Workplace, Homes, Research & Education, Hospitality & Retail, Sport & Wellbeing, and Estates & Masterplanning. Client mix spans private homeowners on complex or heritage-sensitive sites through to enterprise clients including Bremont (new-build watchmaking HQ), Heckfield Place (luxury hotel estate), Columbia Threadneedle (commercial office redevelopments), Landid (Cantay House, Oxford), and Whitbread (700+ room hotel conversion in Victoria).

The firm's underlying technical platform is its partner expertise in retrofit and adaptive reuse, listed-building and conservation-area planning, Passivhaus and net-zero operational carbon design, and an architecture-led interior design model. Specialist hires in sustainability (Robin Eadie) and Passivhaus design (Valentina Gonzalez Saez), together with BIM standards led by Gregg Thatcher, underpin the technical delivery. Documented outcomes include the first BREEAM Excellent workplace refurbishment in Southampton (Twenty3), 1000% biodiversity net gain at Frogmill, and net-zero operational carbon on a previously refused riverside site (Temple Weir).

The business model is fee-based professional services, priced project-specifically by scope and complexity with no published standard pricing. Revenue is generated through direct engagement with landowners, developers, businesses, and homeowners, channelled via website enquiries and the firm's three physical studios across London and the South of England. Marketing relies on a portfolio-led approach: award recognition (RIBA, Tatler, Cond\u00e9 Nast Johansens, House & Garden Design 100), thought leadership articles, and events such as Clerkenwell Design Week. The practice has no external institutional investment, no parent company, and no subsidiaries.
