A private garden for key holders and residents of Mecklenburgh Square.
To fund the upkeep of the garden, Mecklenburgh Square residents pay a compulsory annual levy though their council tax. The amount paid is in line with the residents' council tax banding.
A limited number of keys are made available for external key holders on payment of an annual subscription. The subscription is set by the Garden Committee.
All sums raised go towards the maintenance and improvement of the garden. The garden is open to non-keyholders once a year for Open Garden Squares weekend, usually in mid-June.
