We want to install a glass fence on 1 boundary of our property. The length is approx 21m. The fence is to be attached to the top of an existing keystone block retaining wall. The retaining wall is less than 1m high. We also want a 1.2m high aluminum fence/gate from the glass fence to the house & a 1.8m high aluminum from a side fence to the house. We want the fence built now.
