Our Practice

Architecture that earns its ground.

Founded in 2002 by James Okoro and Flora Brannigan, Meridian Studio has grown into one of London's most respected independent architecture and interior design practices. We work across scales — from a single room to a whole neighbourhood — with the same rigour and the same belief: that buildings should justify their existence.

We are RIBA chartered, Passive House certified, and registered with the Architects Registration Board. We work primarily in London and the South East, with select projects nationally and internationally.

"Architecture is the only art form you cannot avoid. You live inside it, work inside it, and are buried by it. That responsibility — to make it worthy — is why we do this."

Our Process

01

Brief & Feasibility

We begin by listening. An honest feasibility study establishes what is possible within your budget, your site and your planning context — before a pencil is lifted.

  • Site analysis & constraints review
  • Planning history assessment
  • Budget benchmarking
  • Initial programme outline
02

Concept Design

Options are developed and tested against the brief. We present multiple approaches, explain the reasoning, and refine to a preferred scheme through dialogue — not decree.

  • Spatial concept development
  • Material & massing studies
  • 3D visualisation
  • Client design workshops
03

Planning & Technical

Full planning applications, structural coordination, building regulations and tender documentation. We manage the consultants, the programmes and the paperwork.

  • Planning application management
  • Structural & MEP coordination
  • Building regulations submission
  • Tender package preparation
04

Build & Completion

We remain on the project through construction — issuing instructions, inspecting works, certifying payments and resolving issues before they become problems. We hand over buildings, not documents.

  • Regular site inspections
  • Contractor management
  • Snagging & practical completion
  • Post-occupancy review

What Our Clients Say

"The Shoreditch conversion exceeded every expectation. James and his team understood that we weren't just buying space — we were building a life in it. The result is extraordinary. Quiet, considered, completely ours."

Marcus & Priya Halstead
Shoreditch Warehouse Conversion — 2023

"We came to Meridian with a listed building and a brief that everyone else told us was impossible. They not only achieved planning consent — they delivered a restoration that Historic England cited as exemplary. Exceptional people."

The Ferris Family Trust
Heritage Restoration, Somerset — Grade II Listed, 2022

"Flora redesigned our Mayfair restaurant from a blank canvas to a full interior scheme in six weeks. The space has character, warmth and precision. Every material choice was deliberate. Covers are up 40% since reopening."

Dominique Sarthe
Sarthe Restaurant, Mayfair — Interior Design, 2024
