Company Director Oliver Sizeland…

Growing Rooms has evolved into one of Sydney’s leading landscape firms and we have over a decade experience within Sydney.

The company was founded by Oliver Sizeland who has worked within the landscaping industry in both London & New Zealand. Since being in Sydney Oliver has been involved in constructing some of the city’s finest residential gardens.

“I’ve been lucky enough to travel with landscaping and I think it’s important to keep up with what’s happening within our industry in other countries.  I enjoy seeing how designs fit into the different landscapes to make the most of what’s available”.

Oliver started Growing Rooms Landscapes with just one simple principle in mind:

To create stunning and functional gardens tailor made to our clients’ needs”.

A huge vote of thanks to Oliver, Jack, George and the team who took our dream and turned it into a garden more beautiful and tranquil than anything we could imagine. They did this sticking to budget and on time. All were terrific but a special mention to Oliver - he was always lovely to deal with and is a creative problem solver. We keep looking at our incredible garden and are so grateful we found Growing Rooms to create it for us. Couldn't recommend them more highly!

Dr. Ginni Mansberg - Queens Park

We recently hired Growing Rooms to knock down our front wall and replace it with a picket fence and hedge, and to add some other greenery and plants to our front outdoor space. The whole experience was faultless. They helped design the small space and gave us some really good ideas on both the construction and the type of plants which would look good. When they carried out the work every single member of the team was so lovely to work with and got the job done so quickly and efficiently and we are super happy with the end result. We hope to get them back soon to look at our back garden.

After a chat with Oliver about the look and feel we were after for our front garden and carport, he totally got it! He dropped off one sample tile; it was exactly what we were after. We love the look and the finish, and would highly recommend Oliver and his team for a fabulous, professional and friendly job.

We wanted to turn our dreary backyard mud patch into an urban paradise. The Growing Rooms team made that dream happen. They respected our ideas and wants and kept us in touch with every step. All we had to do was sit back and relax.

Growing Rooms quote impressed me because of its detailed breakdown of the project into parts and each part was clearly itemised and costed right down to the name of products, so I would have a reasonable accurate idea of the total cost of the job. I am more than happy with the finished work and would not hesitate to recommend the Growing Rooms team.

John Fear

As you know I run a project management company that deals in major commercial construction projects and I have often found it frustrating when dealing with the significantly less professional trades and companies that often work on small construction projects, typically associated with housing. However, you and your company have given me renewed confidence that some small organisations out there are still providing a highly professional and value for money service.

Dear Oliver, both Wade and I just wanted to express our thanks to you and your team on the fantastic job that Growing Rooms have done. We knew it was going to look good, but you have surpassed our expectations – no easy feat as we have high expectations!
From the first meeting with you & George, the consultation process was one where we felt you listened to our needs but also politely pushed back and suggested alternatives which made sense - you are a true trusted expert. And then when you started the physical work, your team maintained the high level of service – nothing was ever a problem, the quality of their work was consistently excellent and they were always were on hand to answer questions. The end result is a garden which not only looks great but very practical for our family.
Thanks again and I have no hesitation in recommending Growing Rooms.

Paul and Wade - Randwick

I was going to get in touch to say what a brilliant job the boys did yesterday and ask you to pass on my thanks and appreciation.

We are extremely pleased with what Growing Rooms has done to turn our outdoor courtyard into a beautiful space that effectively adds another room to the house. Using their design expertise, they have made the courtyard into a lot more than just a garden

Ingrid - Waverly

Thank you so much Oliver for our beautiful garden. I sit out there most nights and we both marvel at how much it is growing and how beautiful it is looking every day.

Please thank George, Jack and the team also.

We really love our garden.

Jane and Rodney - Breakfast Point

We really like Craig’s work. Our garden looks lovely. 😊 Actually he is the best gardener we’ve ever had since we move here. Really appreciated. 🙂
