Renovations and teardown-rebuilds, taken back to the bones worth keeping.
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
Renovations & Rebuilds in Northumberland.
Renovation asks a different question than a new build. Not 'what do we want here?' but 'what's already here, and what's worth fighting to keep?' We start by reading the existing house — the structure, the systems, the grade it sits on — and telling you honestly which bones are worth keeping and which are cheaper to replace than to save. Sometimes the right answer is a careful reno; sometimes it's a teardown and a fresh footing on the same view.
A teardown-rebuild is its own discipline: demolition, then building back up from the dirt on a lot that already has services, setbacks, and neighbours. We've stripped houses off their foundations and put clean new builds in their place where, driving by, you wouldn't know it's the same property. Reno and addition work carries the same written decision schedule and named allowances as a custom home — because hidden work behind old walls is exactly where budgets get lost.
The advantage of one family on the whole job shows most in reno work. When the wall opens and the surprise is behind it — the re-route, the rot, the thing the last owner buried — the person who has to solve it is standing right there, not calling the office. We finish the flow, the systems, and the finishes, and leave the character that was worth keeping.

Home Renovations & Rebuilds in Northumberland — the basics.
How do I know whether to renovate or tear down and rebuild?
We tell you. After walking the house and the grade, we lay out what each path actually costs and what you get — sometimes the structure is worth saving, and sometimes you're paying more to work around it than to start clean on the same lot. You get the honest version, not the one that's easiest for us.
Can you add to a home we already love without it looking added-on?
That's most of the craft in an addition — matching the line, the materials, and the roof so the new work reads as though it was always there. We design the addition around what the house and the property are already doing.
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.
