About Circle Field Associates

A Unique Fusion of Architecture, Surveying, and Law

Since 2015, we have been providing a rare level of multi-disciplinary expertise to the property and construction sectors. Led by Dr. Koji Tanaka, our firm is uniquely positioned at the intersection of design, technical surveying, and legal strategy.

Dr. Tanaka is not only a Fellow of the Royal Institution of Chartered Surveyors (FRICS) but also a member of the Royal Institute of British Architects (RIBA) and the Chartered Institute of Arbitrators (MCIArb). This means when you work with us, you aren't just hiring a surveyor; you are gaining a strategic partner who understands the aesthetic, structural, and legal complexities of your property.

Resolving Complex Disputes with Authority

When projects stall or disagreements arise, we provide the clarity needed to move forward. We specialise in dispute resolution, acting as expert witnesses and providing arbitration, construction adjudication, and expert determination.

Our deep involvement in drafting International Standards (IPMS, ICMS, and IES) ensures that our advice is not just current—it is industry-leading. We represent a diverse range of stakeholders, from international investors and developers to individual homeowners, ensuring that every project has a clear path to success.

Specialist Heritage and Conservation

We have a profound respect for the past. Our team provides detailed heritage and conservation reports, ensuring that historic properties are managed with the sensitivity they deserve while meeting modern standards.

Whether it is a feasibility study for a new development or a building pathology report for a period home, we combine technical precision with architectural insight. We help our clients navigate the complexities of planning and design while protecting the integrity of heritage assets.

A Global Perspective, Locally Delivered

While our roots are in London, our reach is truly international. With a dedicated office in Japan and a strong network across Europe, the Middle East, and Asia, we support clients navigating cross-border investments and complex international projects.

"We create environments for people to work and live better by providing top-quality advice and wide-ranging support for both local and international projects."

Whether you are an investor looking for strategic development advice or a contractor needing expert cost and delay analysis, we bring a global standard of ethics and professionalism to every instruction.
