About Us

Blackwood Ridge Landscape Design is a collaboration between two passionate and experienced horticulturalists, Dan Sullivan and James Pethybridge.

Working together we aim for a strong focus on gardens with a naturalistic contemporary style from country to coast or for that modern city courtyard.

With our skill in adapting the surrounding environment with our clients needs we design gardens with a seamless link between the home and the outdoor living spaces that evoke a sense of belonging.


Dan Sullivan

Senior Landscape Designer

After working in the horticultural and landscape construction industry for twenty years it was a natural fit for Dan to transition to landscape design fifteen years ago. Dan has worked across three states, Victoria, NSW and Queensland on private gardens and commercial landscapes including work for Architects and Australia’s most awarded home builders. With Dans extensive background in horticulture and landscape construction his garden designs combine practicality and sustainability with natural beauty to ensure you achieve your vision for now and into the future.


James Pethybridge

Materiality and Planting Design

Although James is an awarded chef, he has always had a passion for plants and horticulture.

James has previously owned and operated a retail plant nursery in the Macedon Ranges and an acclaimed boutique restaurant, ‘The Garden Room’ with a focus on only using locally produced seasonal produce on the menu.

After shifting away from his cheffing career it was always obvious he would turn his insatiable interest in plants and trees and his years of horticultural knowledge to pursue a career in landscape and planting design.
