Custom Shops & Outbuildings in Northumberland
Custom Shops & Outbuildings · Northumberland
Working shops, barns, and outbuildings, built to be used hard.
Nicholson Bros builds custom homes and estates across Northumberland County — Cobourg, Port Hope, Warkworth, Brighton, and the farmland and lakeshore in between — from our yard in Trent Hills.
Northumberland runs from the Lake Ontario shoreline up into the drumlin country and the Oak Ridges Moraine, and the ground changes as you climb. Lakeshore lots near Cobourg and Port Hope deal with high water tables, mature trees, and established neighbours who'd rather not watch a bin sit at the curb for a season; the farmland and estate parcels inland give room for a fuller build — a house, a shop, outbuildings — but reward a design that frames the rolling grade rather than fighting it. We read the site first.
A lot of Northumberland building is people leaving the city for a property they mean to stay on, and they care as much about how the work is run as the result. Owning our own equipment and hauling every load of debris in our own trucks lets us work an established lot without turning it into a construction zone for a year — and being the family whose name is on the work, an hour from Toronto but rooted here since 1993, is the accountability these owners are looking for.
What we build
Shops & Outbuildings in Northumberland.
On a rural property the shop is not an afterthought — it's where the trucks live, the equipment gets fixed, the work gets done. We build shops, barns, equipment storage, and multi-use outbuildings to be used hard for fifty years: the right footing and slab for what you'll roll onto it, the doors and heights that fit real machines, the power and heat to actually work in winter. We started in concrete and sitework, so the part underneath is the part we get right.
A shop or outbuilding still deserves to look like it belongs. We match the building to the house and the land — the cladding, the roofline, the way it sits on the grade — so the property reads as one place rather than a house with a metal box behind it. Many of our builds pair a shop with a home or a caretaker's residence, planned together so the services and access work for both.
Same accountability as everything we do: one family, our own equipment, WSIB-covered crews, and a written scope so you know what you're getting before it's poured. Whether it's a standalone shop or one structure of a larger estate, it's built to be worked in — not just looked at.

Custom Shops & Outbuildings in Northumberland — the basics.
Can the shop match the house instead of looking like a steel box?
Yes — cladding, roofline, and siting are all choices, and we make them so the shop belongs to the property. A working building can be built honestly and still look right from the house.
Do you build a shop and a home together?
Often. A shop with a caretaker's residence, or a main house with a working outbuilding, is planned as one project so the servicing, grading, and access work for the whole property from day one.
What's an owner's representative, and how is it different from a general contractor?
A general contractor runs their own crews and answers to their own margin. An owner's representative answers to you. We sit on your side of the table — managing the architect, the trades, the budget, and the schedule on your behalf — so your interests are the only ones in the room. On most of our builds we do both: represent you and run the work.
Will the budget I start with be the budget I finish with?
Closer than you're used to. Every allowance is named in writing during the Design phase, so you choose finishes against real numbers rather than guesses. Surprises come from vague budgets and undocumented decisions — we remove both. Where the world moves on us, you hear about it the week it happens, not at the end.
Do you build on land I already own, or help me find it?
Both. If you own the land, we start by walking it with you before anyone draws a line. If you're still looking, bring us in early — we've spent three decades reading sites across this region, and the right answer often starts with the wrong-looking lot.
