Mosman 2088 · Municipality of Mosman

Landscaping Mosman

Mosman sits on a peninsula between two harbours, and most of its gardens are built on a slope that runs toward water. Terracing, steps and retaining are the real work here, usually around a house worth being careful near.

What we build here

Slope, heritage and reserve boundaries

Mosman sits about eight kilometres north-east of the city, the only suburb in its own municipality, on a peninsula between Sydney Harbour and Middle Harbour. Sections of Sydney Harbour National Park run along its foreshore at Bradleys Head, and a good number of its houses date from the Federation period.

Gardens built as a series of levels

Very few blocks here are flat. The garden is terraces, steps and landings running down toward the water, and the structure holding those levels is where most of the budget goes. Done properly it lasts decades, and done cheaply it leans within a few years.

Working around a period house

Federation houses and older sandstone structures are easy to damage and expensive to repair. Excavation, drainage and new levels near one need planning rather than enthusiasm, and we set out how we will protect what is there before starting.

Foreshore and reserve edges

Where a block runs down to national park or reserve, the lower garden is a transition into bushland. Planting there wants to suit the setting, and what can be cleared or pruned is controlled rather than up to the owner.

What we build

Our landscaping services in Mosman

Almost every Mosman project begins with holding the slope and getting safe access down it.

Paving in Mosman

Stepped paths, landings and terraces paved to a level, free-draining finish. On a fall this steep the setting out of the steps matters as much as the material they are made from.

How we approach paving

Mulching in Mosman

Mulch at a grade that stays on a slope rather than washing to the bottom of the garden, and at a depth suited to a sheltered harbour position.

Weeding in Mosman

Beds, terraces, stairs and paving joints cleared back, roots included. Near a reserve boundary there is steady pressure from regrowth, so regular passes beat one large clear.

What changes a Mosman quote

The grade, the access across it and what you are building next to.

  • How steep the block is. The fall sets how many terraces you need and how high the walls go. We measure it rather than estimating, because on a slope this sharp a guess at the grade is a guess at the budget.
  • How material reaches the work area. Few blocks here have vehicle access to the lower garden. Everything moves by barrow, often down stairs, and that is substantial labour we put in the written quote.
  • What is near the work. Excavating beside a Federation house or an original sandstone wall takes care and sometimes a different method. We set out how we protect it as part of the quote.
  • Reserve and foreshore boundaries. Where a block adjoins national park or reserve, clearing and tree work are controlled. We check what is permitted before pricing anything near that edge.
  • Tree approvals. The Municipality of Mosman controls removal and significant pruning of many trees. We confirm what is allowed before quoting, not after.

How it runs

How a Mosman landscaping job runs

Three steps, a fixed written price, and the site left clean.

  1. Tell us about the block

    Call or send photos showing the fall, the street frontage and the lower boundary. On a Mosman block that is what sets the price.

  2. Free on-site quote

    We measure the grade, work out how material gets down, check the boundary and what needs protecting, then put a fixed written price and a staged plan in front of you.

  3. We build it and clear out

    One crew from start to finish, the barrow runs planned, and all spoil and old material taken away.

Mosman questions

What Mosman homeowners ask us

Our block falls away to the water. Can it be made usable?

Yes, with terracing, and that is most of what we build here. Retaining walls and stepped access turn a fall into a series of level areas. How many levels and how high the walls go depends on the grade, which we measure properly at the quote.

We have a Federation house. Will you work near it carefully?

That is the main thing we plan for. Excavation and new drainage beside a period house or an original sandstone wall need a considered method rather than a machine and optimism. We set out how we protect what is there before any work starts.

There is no way to get a truck to the back garden. How does that work?

It is the normal situation on these blocks. Material goes down by barrow, often via stairs, and spoil comes back up the same way. We plan the runs before quoting, so the labour is in the written price rather than added later.

We back onto national park. Does that restrict what we can do?

Near the foreshore and reserve boundaries, yes. Clearing and tree work are controlled, and planting is better suited to the bushland setting anyway. We check what is permitted before pricing anything along that edge.

Can we open up the view?

Sometimes, within what is allowed. Selective thinning and canopy lifting recovers a surprising amount without removing anything. The Municipality of Mosman controls significant pruning, so we confirm what is permitted before promising a result.

Do you cover Cremorne, Neutral Bay and Balgowlah Heights?

Yes. We work across Mosman 2088 and the surrounding lower north shore and Middle Harbour suburbs including Cremorne, Neutral Bay, Balgowlah Heights, Seaforth and Clontarf.
