    Removal of the two large willow trees on the northern boundary of the property. When we purchased the property several years ago our surveyor advised that having such large trees so close to the property could cause damage to the foundations of the property due to roots. Since we are in a listed property we do not wish the trees to cause damage to either our property or our neighbours. The trees are also too big for their locations. The area would be replanted with small trees or shrubs particularly chosen to attract wildlife such as birds and insects.
