"We worked with Marcio on the design of our first home in the UK, and it was a pleasure from start to finish. He had a remarkable eye for detail and came up with thoughtful, creative ideas that significantly improved both the functionality and feel of the house. He was always approachable, easy to work with, and took the time to understand what we wanted, making the whole process smooth and enjoyable. We are extremely pleased with the final result and would happily recommend Marcio to anyone looking for a talented architect who combines creativity with professionalism."

"Working with Marcio was an outstanding experience. He brought a fresh perspective to every aspect of the design, balancing creativity with functionality in a way that truly elevated my home. His thoughtful approach helped make the space feel more spacious, organized, and tailored to my lifestyle. What impressed me most was his ability to find unique solutions that I hadn't considered myself. I would gladly recommend Marcio to anyone seeking a talented designer who combines vision, practicality, and a genuine commitment to delivering exceptional results."

"Marcio thoughtfully designed my apartment with fantastic insights and creative ideas that made a real difference. He created bright, open spaces and expanded the storage areas, which were my main concerns. I recommend his work to anyone who is looking for a versatile, inventive, out-of-the-box professional."

"Marcio designed our company headquarters in Rome — an outstanding job, with brilliant design, smart use of space, attention to detail and full control of the budget. We hired him again for several residential, hotel, commercial and leisure schemes, and our own apartment. We were consistently satisfied and impressed by his commitment."

"Mr. Grinbaum redesigned our apartment, completely reconfiguring its internal layout. The modifications he proposed completely changed the environment, vibrations and even our mood. It was a lifestyle change."

"Marcio E. Grinbaum is a most accomplished architect. He directed major refurbishment works at my house more than ten years ago. We hired him again for our new extension, which is now completed and looks perfect. I called him back because I trusted his excellence, imagination and flexibility. I would definitely recommend Marcio Grinbaum."

"Marcio is well known as someone who loves his profession, always keen to advise us on all matters related to architecture, design and building issues. Having seen his very impressive portfolio, I commissioned him to redesign and refurbish our villa in Waterloo. He transformed an ordinary old house into our dream home, with very effective solutions and innovative ideas. I am now considering buying another property in France and commissioning him again for that project."

"Marcio Grinbaum was recommended to us in 2009, after we started a new residential development in Brazil. We had hired a local architect to draw the plans and obtain approvals, but weren't happy with the result, so we approached Marcio for alternatives. He was incredibly helpful, quickly offering ideas to improve the layouts without adding cost or delay to the programme. He skilfully redesigned the internal layouts of the flats, keeping the structural elements but creating much better, more flexible spaces — changes that made the apartments far more attractive to potential buyers, and more saleable. We were delighted with the result and don't hesitate to recommend him."

"We commissioned Marcio for the redesign and extension of our house in London. He came with fantastic suggestions, which we implemented. The result was much better than we expected, and we now have great spaces with lots of natural light. We are delighted with the end result and highly recommend Marcio."
