The business is a professional services firm monetizing project-based fees denominated in GBP, ranging from tens of thousands to multi-million-pound commissions. Go-to-market is direct, relationship-led engagement with private clients and institutions, supported by a Squarespace portfolio site, industry awards (AJ Retrofit, BIID), and earned media (Elle Decoration).

Direct peers

• Tonkin Liu: London-based award-winning architecture practice of similar boutique scale working on cultural, residential, and heritage projects. Comparable ethos, award profile, and high-end residential and cultural client mix.
• Allies and Morrison: London-headquartered architecture practice of comparable scale working across residential, commercial, and masterplanning projects with deep London planning expertise. Comparable mix of high-end residential, commercial, and heritage work and similar boutique-to-mid-size positioning.
• Purcell: UK heritage architecture specialist working on listed buildings, conservation, and adaptive reuse at scale. Most direct competitor for the listed-building-consent and conservation-area commissions central to JMA's premium positioning.
• John McAslan + Partners: UK practice with strong adaptive-reuse and heritage credentials, including award-winning conservation projects. Comparable in scope (residential, cultural, commercial) and in pursuit of similar estate and institutional clients.
• Caruso St John: London/Zurich-based practice with a heritage-sensitive, craft-led design ethos strongly aligned with JMA's listed-building and conservation focus. Both firms compete for the same kind of culturally minded, premium-fee clients in the UK and internationally.
• David Chipperfield Architects: International practice globally renowned for heritage conservation, museum, and cultural-sector architecture. Overlaps directly with JMA's gallery, cultural-space, and listed-building commissions and is a benchmark for premium heritage fees.
• Reardon Smith Architects: London-based practice with significant heritage and conservation portfolio, including listed buildings and cultural-sector work. Direct overlap on the listed-building-consent and conservation-area specialism central to JMA's offer.
• Studio Egret West: London-based architecture and urban-design practice working across residential, commercial, and cultural projects. Comparable boutique-to-mid-size positioning with similar central-London client mix.

Broad incumbents

• Foster + Partners: Global architecture incumbent with broad portfolio spanning commercial, cultural, residential, and heritage work. Larger and broader than JMA but competes for the same institutional, estate, and cultural-sector commissions at the top of the market.
• Zaha Hadid Architects: Global architecture incumbent with London presence working on cultural, commercial, and high-end residential projects worldwide. Sets the upper bound of premium-fee cultural and gallery commissions JMA also targets.
