I first met Zaha back in the 1980s. Zaha had already set up her own architectural practice and I had just left Christie's and was on the cusp of opening my own gallery. During that era London really felt like the hub of global creativity. The city was emerging from the social, economic and political gloom of the 1970s and was rapidly taking over from Paris. Zaha had grown up during turbulent times in her home country of Iraq, but for her, like many of us, it was London where she finally settled. It was London that seemed to offer all the chances and possibilities to the creative, ambitious individuals that we all were.

Zaha was always someone whose drive and vision were readily apparent. You instantly knew you were in the presence of a woman who was going to change the world. In 1988 when MoMA featured her work in the show 'Deconstructivism in Architecture,' curated by Philip Johnson and Mark Wigley, it really felt as though a stamp of official acceptance had been given to her work. What had always been considered the furthest edge of the extreme avant-garde of architecture was at last edging into the light.

Throughout her career Zaha continued to push expectations of what we thought could be possible. Both as an architect and as a designer, she understood the cult of the personality and realised that she had to be visible to win projects on a global stage. She understood that it was her very individualism that was the key to pushing her practice and her theories of architecture and design forwards to a wider audience. Whether designing sets for major pop acts or working in fashion, from creating furniture that was seemingly unimaginable to appearing on Desert Island Discs – Zaha always understood that it was her visibility across a multitude of platforms – not just the architectural - that would ultimately allow an international audience to embrace both her and her work.

Zaha was always well aware that being a woman, in what was often considered a man’s world, offered an inherent set of issues, both as an architect and as a businesswoman. But as with everything, she only saw this as another challenge she had to overcome and triumph. Through her indomitable spirit she won contracts all over the world and she pushed our very beliefs in what shape and space could be – whether in a building or a table. She threw away traditional ideas of form and function and she made us all catch our breath whenever we saw her work. Everything she touched, whatever it was, you always knew that it was from the hand of Zaha.

When we first began to talk about working together, it was typically Zaha. She didn’t want to launch in London, she wanted to unveil her first collection – Dune Formations – at the Venice Art Biennale in 2007. The result was incredible and together we showed the world an interior landscape that confounded the very ideas of what furniture could be. The pieces bled from the vertical to the horizontal and tore up the book in terms of what was possible with 3D modelling at that time.

That collection set up a relationship between Zaha and David Gill Gallery with collections that examined materials such as metals, resins and acrylic offering an assault on what was considered possible for furniture and the conventional laws of design. It seems almost poignant however that her final collection which we launched this autumn actually revealed Zaha to be looking back in time, towards the 1950s and 1960s working in more traditional materials such as woods and leather.  The shapes still offer a dialogue in the aesthetics of flow, but the materials perhaps show a slightly different side.

I miss Zaha terribly, not only because of her genius but also for her unending spirit to seek and discover, to experiment and to never give up. Every generation is lucky to lay claim to a small collection of truly creative talents, people and minds that will leave an indelible mark on the world that they leave behind them. Zaha is one of that small group, one that our generation can say has truly changed our lives and our world for the better.

We will miss her vision, we will miss her laugh but more than anything we will miss our very dear friend.
