The move, in the design practice's 40th year, to employee ownership is part of a period of expansion for the design practice and coincides with opening three new studios in Bristol, Cambridge and Manchester.
LDA design chairman Andrew Harland said: "This move is a bold and exciting one for us. The board wants to share the business to grow it and believes this to be the right way to secure a long and bright future.
"We have always wanted LDA Design to not be about individual egos but the brilliance of the collective. That aim holds true and we want to see a future where all of our employees can help to shape our business. This will put us in an even stronger position and make succession planning easier."
While the decision has been made, the details have yet to be finalised. Harland estimates that it will take about two years to complete the process and to set up an Employee Ownership Trust.
LDA Design’s landscape-led practice is made up of masterplanners, urban designers, landscape architects, ecologists, and town and environmental planners.
