Design, construction, decks, walls and planting from one Mona Vale studio. You sign off a scaled drawing and a fixed, itemised proposal before anyone digs.
A scaled plan of your whole outdoor space, drawn around how you live, costed honestly before anything is built.
The whole outdoor space, designed and rebuilt: levels, drainage, structures and planting, sequenced once and done properly.
Hardwood decks and pergolas built on engineered footings, certified where required, made for salt air and bare feet.
Engineered sandstone, block and sleeper walls that hold the hill properly, with the drainage that keeps them standing.
Planting schedules built for salt wind, sandy soil and busy owners: locally native, water-wise and guaranteed to establish.
The honest middle option: new planting, edges, mulch and small repairs on bones that are still sound.
Scheduled care that keeps a designed garden looking designed: pruning, feeding, mowing and the small fixes done early.
Grounds care for strata schemes, offices and holiday lets: fixed scope, scheduled visits, photo reports your committee can read.
We walk the block with you, measure it properly, and talk budget honestly. How you live outside drives the design.
A scaled plan with structures, materials and a full planting schedule, priced line by line. You sign off the drawing, not a guess.
Earthworks, drainage, structures, then planting, in that order. The site is left safe and tidy every single evening.
Planting to the schedule, mulch, irrigation checks, then a walkthrough against the plan and a 12-week establishment guide.
What our itemised proposal locks in, and the shortcuts we will never take.
New planting, mulch, edging and small repairs on the bones you already have. The honest option when the structure is sound.
A new deck, pergola or retaining wall with the garden rebuilt around it. Our bread and butter on Northern Beaches blocks.
The whole outdoor space designed and rebuilt: levels, drainage, structures, planting. Needs a real design and sometimes council approval, all handled by us.
Scheduled grounds care for homes, strata and commercial sites: pruning, mowing, gardens kept to spec, reported each visit.
Two free tools: one gives you an honest steer between a refresh, a rebuild and a full redesign; the other a realistic range in under a minute. Both store nothing, and both end in a design visit, not a hard sell. Neither is a quote.
Decks, pergolas, retaining walls, paving and drainage we build, warranted in writing for five years. We built it, we stand behind it.
A 12-week establishment plan with every project. Follow it and we replace any plant from the schedule that fails in the first season.

“Headland block, full salt exposure, and three landscapers had already told us "nothing grows there". Hazel drew a plan that worked with the wind instead of pretending it away. Two years on the garden looks better than the drawings, and the grounds team keeps it that way while we are in the city.”
“Our deck was condemned and the yard behind it was basically a cliff. Fernline terraced the slope, engineered the new wall, and the deck went up on certified footings with all the paperwork. The quote named every timber and every plant. Nothing was vague and nothing moved.”
“They talked us OUT of the big rebuild. Joel showed us the bones were fine and the real problem was drainage, so we did ag-lines, soil work and a replant for less than half our budget. The lawn survived winter for the first time in six years.”
“Everything we planted before Fernline died by autumn. Their planting schedule listed every species with where it goes and why it copes with the salt. We followed the 12-week plan and lost exactly one plant, which they replaced without being asked.”
“Steep block backing onto bush, BAL requirements, council tree rules, the lot. Fernline handled the engineering and the permits and still built us terraces we actually use. The wall has been through two big wets without a millimetre of movement.”
“We manage eleven schemes and the grounds reports from Fernline are the only ones committees never query. Fixed scope, photos after every visit, and problems arrive as a flagged quote instead of an invoice surprise.”
“The design fee felt like a leap until we saw the drawings. Suddenly three competing quotes were comparable because ours was the only scope anyone could actually price against. We built with Fernline and it landed on budget to the dollar.”
“A six-by-four courtyard everyone said was too small to bother with. Fernline designed it like a room: built-in bench, espaliered natives, lighting. It is now the best space in the apartment and the body corporate approved everything first go.”
“Monthly care visits for two years now. The garden still looks like the day they handed it over, and the visit notes tell me exactly what was done and what is coming next season. Worth every cent of the $250.”
