Why not have a timber pergola archway designed and built to your specific requirements ?
A timber pergola/archway is a great addition and asset to any garden it can transform the look quickly and simply, by creating an immediate 3rd dimension.
Used along with screening panels it is a great method of quickly dividing up the garden or screening unsightly areas.
Depending on the situation they can either be free standing or against an existing house gable wall or shed.
As shown they can be used to direct pedestrian flow at the same time providing immediate partial screening - the amount of screening shall improve in time as the planting of climbers becomes established.
