Ponds have become a extension of the home like patio's and decking. With modern building products a pond can be a very stylish addition to any property as this photo shows. 

Design is in the eye of the beholder , but what as to be incoporated into a design is practicality. The filter must be accesible , lights must be easy to replace as over time the bulbs will need replacing , the water volume must be enough to sustain life and not let it turn into a stagnet mess. after all these things considered a well designed pond is very stylish and will get nothing but admiration.
