Outdoor Luxury · Whitby, Durham
Outdoor Living Spaces in Whitby.
Whitby is one of the closest towns to our Hampton base, and we have worked across Durham long enough to know its streets well. From the heritage homes near the downtown core to the estate properties and acreage around Brooklin, we bring fifty years of natural-stone craft and owner-led landscape design to homeowners here — the same crews, the same equipment, and James involved from the first walk of the property to the last stone set.

In Whitby
Landscaping that belongs in Whitby.
Whitby spans a wide range of property types, and the right approach changes with each one. The older neighbourhoods around the historic core hold century brick homes on generous lots with mature trees — settings where heavy machinery has to be worked in carefully and new stonework needs to sit comfortably beside what is already there. Because we own our equipment and haul all debris away in our own trucks, we can move through an established street without tearing it up or leaving a bin parked on the driveway for weeks.
North of town, Brooklin has grown into a mix of established village streets and newer executive estate properties, with true acreage and rural lots on the edges where Whitby meets the countryside. These are the larger canvases we are built for — full design-build work where a stone patio, retaining walls, planting and water can be planned as one landscape rather than added piecemeal. On the bigger parcels, grade and sightlines matter as much as the stone itself, and that is the kind of planning we do at the design-review stage, before anything is dug.
Homeowners in Whitby tend to be making a once-in-a-generation investment in a property they intend to keep, and they care about how the work is done as much as the result. The soils shift as you move north toward the moraine, drainage and frost depth have to be respected, and mature trees are worth protecting rather than working around carelessly. We treat all of that as part of the job — a clear proposal after we see the site, daily communication while we are there, and a finished landscape built to outlast us.

The craft
Built from the ground down.
An outdoor living space is the part of a property a family actually uses — so we build it to the same standard as the rooms inside the house. The work spans outdoor kitchens, fireplaces and fire pits, pergolas and pavilions, full landscape lighting, and the seating, dining and lounging areas that tie them into one place you can spend an evening. Everything is designed as a single composition, anchored in natural stone, and laid out so the cooking, the fire and the gathering all face the same direction — toward the people you built it for.
The masonry is where this work earns its place. James is a third-generation stonemason, and the kitchens and fireplaces are built the way a chimney is — proper footings below the frost line, a structural core, and a hand-laid natural-stone face rather than a veneer pinned to a box. Outdoor kitchens are framed for the equipment they'll carry, with stone counters, weather-rated cabinetry and the gas, water and drainage run in before the first stone is set. Fireplaces and fire pits are built to draw and vent correctly, sized to the space so the heat reaches the seating instead of climbing straight up. Pergolas and pavilions are set on real foundations to hold their line through Ontario winters, season after season.
Lighting is treated as part of the build, not an afterthought wired in at the end. We layer it — low light washing the stone, soft fill at the steps and paths, a warmer pool over the dining and fire areas — so the space stays usable and beautiful well after dark, through three seasons of the year. The result is one continuous outdoor room: a place to cook, eat by the fire and stay outside longer than you planned, designed and built by one crew so the kitchen, the hardscape, the lighting and the planting around them all read as a single, deliberate whole.
Because Astonia owns its own equipment and hauls every bit of debris away in its own trucks, a build of this scale moves on its schedule, not a subcontractor's — and your property stays clear, with no rented bin parked on the drive for weeks. James runs the project himself and stays in daily contact from the first layout to the final light being aimed. Crews are WSIB-covered and the company carries $5M in liability insurance, and as a Unilock Authorized Contractor we build to a standard that's independently backed. It's a serious, once-in-a-generation investment, and we treat it that way from the day the stone arrives to the night you first light the fire.

Good to know
Outdoor Living Spaces in Whitby, answered.
Yes. The masonry is built for Ontario winters on footings set below the frost line, and the fireplaces and fire pits are sized and vented to throw heat toward the seating — so the space stays comfortable well into the shoulder seasons. With the lighting layered in, most clients use these areas three seasons of the year rather than just the warm weeks of summer.
We plan and coordinate all of it as part of the build — the gas line for the cooking and fire features, water and drainage for the kitchen, and the wiring for layered landscape lighting — and it's run in before the stonework goes up. Because one crew designs and builds the whole space, the services are roughed in at the right stage instead of being retrofitted later, and licensed trades are brought in where the work calls for them.
We design and build across the GTA & Durham region — including Toronto, Etobicoke, Mississauga, Brampton, Oakville, Vaughan, Markham, Newmarket, Aurora, King City, Whitby, Oshawa, Bowmanville and the surrounding areas.
Every project is different — from focused stonework to a full landscape transformation — so we provide a clear, detailed proposal after an on-site consultation rather than a generic price. Most of our work is a meaningful, lasting investment in your property.
Timelines depend on scope, and you receive a realistic one at the design-review stage before we break ground. Because we own our equipment and run our own crews, we work efficiently — starting at 7:00 AM and keeping the site clean every day.
Yes. We carry $5 million in liability insurance — above the industry average — our crews are fully WSIB covered, and we are a Unilock Authorized Contractor.
