The changes are intended to help broaden membership of the Institute, now in its 85th year, by bringing in more people, including those still studying and at the start of their careers and those who may not be UK-based. They also allow for the creation of a new form of non-chartered membership.
Institute president Noel Farrer said: "This is a mandate for modernisation and future success. Our members have given huge support for the LI to embrace the increasing importance of our urban and rural landscapes.
'It allows us to reach out and encompass the needs of a widening group of professionals involved with the landscape and to give us a more powerful voice to influence decision makers. There's still a lot of hard work to do but the aim is to increase membership, increase influence and maintain the highest possible standards."
The LI will now be making detailed proposals for the way in which the motions will be carried out. These proposals will be incorporated into a revised charter for members to vote on.
More than 600 members voted in person or by proxy ahead of the meeting. The full details of the vote are available here.The full
