Alpine Estate, New Jersey As part of a large estate in northern New Jersey, we are landscaping the seven plus acre grounds for an English style manor house. As you enter into the estate past a tree lined pond you arrive into a lushly planted motor court. As part of the private gardens, a great lawn will be flanked by Horsechestnut and Cherry trees. There are also boxwood parterres to be filled with Roses and hydrangeas for seasonal color and fragrance.
