Our expertise and creative team thinking will help you realise your vision.


In 2006, Steve Warner established OUTHOUSE design as a fresh, customer-focused landscape design and horticulture consultancy. The focus for Steve and the team is you, the client – this is your outdoor space or garden, and our role is to listen to your needs and inspire you with our ideas.

Since then, we have delivered a broad range of projects from innovative, award-winning residential gardens to extensive master planning of community spaces. The key strength of our team is our drive to create sustainable places for people to live, work and enjoy. We love what we do, and really enjoy sharing the creative process with our clients, to come up with a design we are both proud of.

We are passionate about creating the ‘outdoor living experience’ and we are grateful for the trust our clients have in us. We appreciate that the planning involved in creating a garden is becoming more intense, but seeing the end result – months or years later – makes it all worthwhile. The partnership is our passion, and our clients keep us inspired.

“Consider what’s possible.”

Steve Warner established OUTHOUSE Design as a landscape design and horticulture consultancy in 2006 and since then the practice has evolved into a complete landscape management service. This business was developed to compliment and further Steve’s experience over a number of years as a Landscape Design Officer for two local government authorities.

Throughout Steve’s career in both local government and in OUTHOUSE Design, Steve has been responsible for the direction and management of many projects working with Architects,  Engineers, Playground Designers and Landscape Construction companies. This exposure has provided insight into the vast number of factors which ensure a successful project including, supplier selection, community consultation, budget planning, materials selection and contingency planning.

Steve’s experience focuses on the design, documentation and construction supervision of an extensive range of Open Space projects. These projects include All Access playspace design, local and regional park design, environmental rehabilitation, landscape maintenance consolidation, and therapeutic and educational design.
