“What I value most about B/M Architects is their aesthetic sensibility and sense of harmony, combined with their ability to remain practical and adapt to the constraints of the real world, where resources are defined and limited. In addition, they maintain a close and fluent relationship with us. Their constant availability and flexibility, evident at every stage, bring ease and confidence to the development of the projects we carry out together at ESAC.”

“The renovation Mireia has done in our house has been careful, meticulous, tremendously organic and aesthetically natural and beautiful.
She is also very honest, realistic and resolute, which makes her very easy to deal with, every step of the way.
I also felt that he respected my ideas but always contributed his professional point of view, making the result better than we expected.

“Their creativity and their ability to take my suggestions and requests for changes seriously are a major strength – and something very hard to find. We exchanged countless drafts, and the result was always improved. Even after 12 years of living in the new house, looking back, there are only a few small things I would have done differently.”

“We really enjoyed working with you. There was always a pleasant atmosphere, and we felt that you truly ‘listened’ to us. By listening we mean that you always took our concerns seriously and tried to make them a reality. We especially enjoyed sharing the creative process with you. You contributed many great ideas to the project, and it was clear that you were passionate about your work. The result of all this effort – the Burbujas House – was first-class.”

“Oliver Bieniussa has clearly demonstrated his professional ability in the El Greco Congress Palace project in Toledo. After playing a key role in its drafting and design, he went on to assume full responsibility for the project, managing the day-to-day issues on site. Completed in December 2012 with a budget of €43 million, it is a complex urban development in the heart of the city that includes a public escalator system linking the lower level with the historic old town, a 1.000-seat auditorium, convention and exhibition halls, a restaurant, and parking for 600 vehicles.”
