Studio & Clients


Maria Barceló / Founding Partner

Led award-winning architectural practice BAB for many years, where she developed the company’s reputation for historic restoration projects. Chartered as a Landscape Architect in 2004, she has worked in London, Madrid and Buenos Aires, and has an impressive breadth of experience. With a background in Biology and ecology and well established in the academic world, Maria lectures at Masters level in Landscape Architecture. Analytical in her approach, Maria has to get under the skin of a place and really know it from the inside out.

Isabel Wrench

Has a heritage and tourism background, re-training in Landscape Architecture as a mature student and now a member of MIX studio. A knowledgeable plantswoman, she is on a mission to tip the balance in favour of soft landscaping over the current trend for impermeable outdoor ‘rooms’. Raised at 18th century landscape gardens Stourhead in Wiltshire, she is particularly interested in historic gardens and still leads garden tours and occasionally lectures in garden history.

Anabel Fernández Rubio

Architect and Urban Planner from the Escola Tècnica Superior d’Arquitectura de Barcelona (ETSAB) with more than 20 years of professional experience in the international arena. Anabel´s work methodology is based on a meticulous assessment of current trends in urban planning, with a careful approach to detail, using sustainability and technical innovation as the foundational blueprint. Her LEED membership and role as Visiting Professor at University College London - Bartlett School of Planning for the past 3 years, provide her with  a unique set of skills. 

Martín Mirás

Hails from Galicia, north western Spain, and has had a keen interest in plants and gardening since childhood. He enjoys experimenting with propagation and as a result operates a small amateur nursery. He also runs a market garden specialising in heritage tomatoes. Having studied as a Landscape Designer, Martin is now carrying out independent design and build projects in Spain. We are fortunate to have him as a consultant for Studio Mix where he is our go to expert in 3D modelling.

Xoán Pérez / Founding Partner

Was born with his fingers in the soil and was raised in Galicia, learning early the skills of tending vegetables and pruning vines. He trained as a Forest Engineer but after moving to London, and with a Masters in Landscape Architecture, worked with diverse Landscape studios Europe-wide. His interest in socio-economic matters has led him to be part of a number of not-for-profit projects and to graduate in international development in 2018. Xoan has never lost touch with the soil however and is a skilled and sensitive gardener as well as a designer with a profound understanding of ‘designing with nature’.


Mais Kalthoum

Has worked in studios in Syria, Lebanon, the UK and France. Born in Homs, Syria, she graduated as an architect from the University of Damascus. In 2018 she completed her Masters in Landscape architecture at the University of Greenwich, with her thesis project, The Island Factories, becoming the runner up at the Barcelona Biennial of Landscape Architecture awards. Mais is a sensitive designer with a rare talent to develop design concepts and a keen interest in collecting and mapping social information.

Lucy Grevers

Has worked with Martha Schwartz, where she developed her eye for design and how to engage with graphic representation to communicate a landscape. With a hands on approach, she enjoys sketching and exploring the interactions between the urban environment and nature. It is important to her that a landscape can perform holistically to address a wide range of social and environmental demands. A key aspect to her design work looks at providing ecologically sensitive places that people can enjoy. 

Sigita Simona Paplauskaite

Is a Brussels-based artist and landscape choreographer. With over a decade of professional experience, she uses landscape architecture as means to sensitize and allude to the human history of sharing urban and natural environments. Her artistic work is often collaborative and performative, and focuses on highlighting environmental risks and expanding the boundaries of the sensorial world. As part of her not for profit work, Simona created ´The Building Site´, one of the few highlight installations at the London architecture festival in 2018.



From planting consultancy for parks, to historic restoration expertise and private residential projects, at MIX we play to the strengths of our diverse team. While each of us has our own specialism, we also know that through collaboration and sharing our skills comes the power to deliver a better product. We believe that quality landscapes make for a better quality of life.

At MIX we eschew trends in favour of delivering holistic design. We find that by adhering to our very simple design philosophy; People and Context, we get it right for the client and the environment.
