With this addition there is a complete line of hides so nowhere for the birds to see humans walking by. The image above shows the window area.This gives a major advantage for large lenses and film cameras. The Gateway admission is £10.00/person and can accommodate 6 persons. 
The Tower hide. This has a partial roof as protection should the weather be fickle, a bench is fixed at the rear of the hide and coat hooks are on the left side.
It has a green line on the floor behind which standing is permited.
The Tower is just over 6 meters (20ft) wide, and about 2.1 meters (7ft) deep. The floor is 1.2 meters (4ft) below the existing hides roof line.
The roof is 2.1 meters from the floor.
Benches and coat hooks are under the roofed area.
Limited to maximum of 4 persons with tripods (5 without) at present.
Clothing. As you will be very visible above the roof-line it would be prudent to wear unremarkable colours..
Access to the hide should be at least 10 minutes before feeding begins as trials have shown disturbance to the birds when heads first pop above the parapet.
