Michael Sackey

Michael is an interior designer with 22 years experience across the design sectors of retail, restaurant and corporate workplace design. His creativity and strong technical knowledge means he is well placed to develop projects from initial concept stage through to completion on site.

Throughout his career, Michael has worked with a variety of clients on both consultancy and design-and-build projects.

“I have a passion for design and its implementation, and interior detailing holds a particular fascination for me. I believe that details are of key importance in interior design. We live in close contact with edges and surfaces of floors, walls and furniture so our sense of pleasure and comfort in being in a space comes not only from the general sense of shape, colour and material but also from the awareness of details that we see and feel at close range.”
