For me, the best work comes from collaboration with people you learn from, respect and trust. John Gilsenan and the team at Westgreen represent these values and quite simply, I can not imagine doing anything in our home or in the River Cafe without them.
— Ruth Rogers CBE, The River Café
For a decade now, Gagosian has partnered with Westgreen on exhibitions, new premises, and now our second major refurbishment project.

Westgreen exceeded my expectations. The whole project was seamless and I felt reassured throughout knowing I had Westgreen on my side.

Westgreen were employed by The River Café to undertake the complete refurbishment of the restaurant following a fire in April 2008.

We needed a high quality gallery and office fit out with no flexibility on the completion deadline. Westgreen achieved this for us and were at all times helpful and approachable and seemed to desire the same quality of finish as we did. There was a very complicated element to the project, both structurally and administratively, requirements changed on an almost daily basis as demands altered the design, Westgreen dealt with these delays and changes with apparent ease – although I know it was anything but easy! We are thrilled with the result.
— Kathleen Dempsey, Cristea Roberts Gallery

“Working with Westgreen always feels like a collaboration. Even in the most demanding situations there is never a question of whether the desired quality can be achieved, rather it is a matter of having detailed and constructive conversations about how the challenges can best be met. A quality of culture and engagement permeates Westgreen from John Gilsenan down to the people on site.

“I look forward to our next project together.
— Adam Caruso, Caruso St John Architects
