Incorporating philosophy, aesthetics, economics, and theories as well as practicalities, it’s no wonder that planning a garden design can overwhelm. In this class, designer Tony Bernstein, Principal at SLDA Landscape Design Associates, will teach about core design principles, but will also coach you to clarify what you desire of a garden. Through exercises and discussions, he’ll encourage you to be introspective to develop design concepts that are reflective of your personality and lifestyle. Melding your inner visions with external factors, you will begin to develop a satisfying and cohesive garden design. In this class you will explore design foundations, philosophies, aesthetics, sensibilities, and practicalities. You will finish the class with rough sketches and plenty of ideas to develop during the winter.
