This following photo is what the pond really looks like. It is just a depression made in the earth then lined with black builders polythene. For me I chose the platform style made up from old fence palings and laid out to form the look below. You can choose to landscape yours with soil, stone plants , pother's or whatever you like - the possibilities are endless. Please note that I have not used any nails or fasteners for easy dismantling of maintenance
The advantage to the pond is that it attracts other animals plus what I like is adding another element to the garden - the missing one -Water. Bit too out there for some but I think the idea of the four elements air fire water earth is part of the balance in gardens. Introducing things like frogs, insects, fish and water plants creates a new eco-culture in it's own environment and this in turn has an effect on the culture of the garden you are creating. Diversity is the key to balance and this in turn determines the levels of health.
Anyway hope this may interest someone out there
