Studio Tashima is a London-based studio of architects and designers known for their intuitive and responsive architecture. Their signature is the resourceful adaptation of existing materials and structures, conjuring new uses and atmospheres rich in quality and experience. Seeing their designs as just one of the many phases in a building's life, the studio’s concept of ‘a living architecture’ reflects a deep appreciation for the built and natural environments while bringing something new.

Charles Tashima was born in New York City and studied at Wesleyan University in Connecticut and Harvard University GSD. Upon graduating with the thesis prize in 1991, he received a Kennedy Travelling Fellowship to follow LeCobusier’s ‘grand tour’ of 1911. Here, he focussed on the study of vernacular architecture and materials through Eastern Europe, Turkey and Greece.

Charles’ collaborative approach has come from his extensive experience teaching design internationally. He began at the ETH-Zurich while working in the practice of Meili Peter Architekten. Since then, he has been a visiting critic at a number of schools and taught at the EPFL-Lausanne and The Architectural Association, London, where he was Academic Head and a tutor for nearly 15 years. While teaching, he founded his practice, Studio Tashima, in 1999.

Chris provides 16+ years’ experience. As a design director he contributes a broad strategic expertise from across AKT II’s global retrofit portfolio: from the unprecedented restoration at Shrewsbury Flaxmill Maltings, and the forthcoming retrofit of London’s Cambridge House Hotel on Piccadilly and New

Zealand House in St. James’s with The Crown Estate.

In western England, Chris has overseen the transformative heritage regeneration at Shrewsbury Flaxmill Maltings: the world’s first iron-framed building. The project has received a plethora of awards, including the prestigious European Heritage Europa Nosta Award in Conservation and Adaptive Reuse.

Here in London, Chris has been running and supporting The Crown Estate’s, New Zealand House transformation project. Chris has instilled in the design team the need to work with the existing structure over his eight years on the project, which has led to less than 10% of the structure needing remodelling, while still delivering a rejuvenated first class building. On Piccadilly, Chris has championed the redevelopment of the listed old In and Out Club, into the forthcoming Cambridge House Hotel, where the 1760’s villa, once home to one of our past Prime Ministers will be converted into London’s next boutique hotel as the hotel sits next to the Piccadilly Line, a complex scheme of acoustic isolation was drawn up where the Grade I and Grade II buildings all now float on over 550 bearings. Most recently, Chris has begun contributing to the transformation of the former Ku Klux Klan auditorium in Fort Worth, Texas, where repurposing a monument to hate will become a beacon of truth-telling, reparative justice, and liberation.

Across all these varied contexts, he’s been championing the maximum reuse of each site’s existing structure – applying a ‘first principles’ approach – to help drive a unified AEC response to the climate crisis. This approach has earned Chris a spot on Buildings 40 under 40 list in 2025.

David Green has been associated with Belsize Architects for 30 years and a director for half that time. A significant part of Belsize Architects’ portfolio has involved work on existing buildings. The built environment is in his blood as his engineer father worked at the Building Research Establishment (before its privatization) on innovation in the use of concrete. In addition to his role at Belsize Architects, where he champions sustainability, he has also made public contributions to built environment policy, most recently contributing to the Don’t Waste Buildings initiative which is seeking to influence political opinion to ensure our existing stock of buildings is used in the best way possible, both for citizens and for the global environment.

He is not a qualified architect, but was educated as a classicist and then economist at Cambridge and the University of Wales. He had an earlier career in the Bank of England, IMF, FSA and FRC and has co-authored books on global financial regulation and on central banking. In consequence the economics of the construction industry is a particular interest, as is the role of financial incentives in promoting the reuse of the existing stock of buildings.

Eoin co-founded London based ConForm Architects in 2017, with the practice working across the residential, cultural, retail, public, conservation, commercial and office sectors.

In particular, he led the delivery of Holbein Gardens, the first Grade II listed building to achieve BREEAM Outstanding in the UK, which set a benchmark for office retrofit and stands as one of London’s most sustainable workplaces.

Architecture offers a vocabulary of different professional lives within one field. It is a field in which you can develop yourself and concoct a route towards a manifesto of ideas, underpinning an architecture of our time.

The profession has a duty to conserve our present cultural fabric by way of sensitive adaption, renewal, alteration, amendment, extension or reconfiguration. Conservation and repair brings with it the joy of meeting the long dead architectural mind of the original designer through intense study and the built work. We have to respond to the value of the existing building fabric by using our architectural intelligence and understanding. We do not need a special label. We are architects, not space planners or old building experts or developers' hacks or designers of follies.

There is also the recognition that the language of architecture and cultural artefacts applies equally to the new and the old - I don’t see a distinction between designing a building and designing the repair of a building. To design a new door is identical to the process of repairing an old door within an adopted set of criteria. Each project demands an orderly mind to establish an approach.

Satisfaction also arises from working with fellow professionals who share a willingness to engage with existing and new fabric in a serious intelligent and knowledgeable fashion. Simply asking the client what they want abdicates the need for informed debate and the giving of professional advice. All parties need to grasp a level of understanding equal to the significance of the design task in hand. The absolute responsibility of each contributor cannot be delegated.

The greatest obstacle to communication in any specialist sector of a profession is the distance the generalist needs to travel to reach a level of meaningful engagement with the specialist. The generalist architect isn’t trained in the field of conservation. We often have to start at a teaching level to establish the vocabulary with fellow professionals. They can’t understand what we do if they can’t come some way towards understanding the definitions of the words that populate our language.
