More space, added the smart way — an addition that outperforms the house it joins.
An addition has to do two hard things at once: respect the house that's already there, and give you space that feels like it was always part of the plan. We build additions in ICF so the new structure is stronger, warmer and quieter than what it joins — and we manage the tie-in so the transition is seamless.
From bumping out a kitchen to adding a full second wing, DMT handles excavation, footings, foundation and walls as one accountable contractor, working around your household with as little disruption as possible.
Additions are notorious for being the coldest room in the house. A continuous R-22+ ICF wall ends that before it starts.
Concrete walls give the connection between old and new real rigidity — no flex, no cracking drywall at the joint.
Concrete-and-foam walls keep street and yard noise out of the new space.
ICF stands up to the elements mid-construction better than open framing, which matters in an occupied home.
Scope, spelled out. Here's what this service covers on a typical project:
The original stone fireplace stayed. Everything else — footings, foundation, structure — was built new around it.

An urban infill teardown: old structure out, new engineered footings and foundation in — on a tight lot between existing homes.
Read the project story →With more than 50 years of combined experience, DMT Building Group self-performs its scope: consultation, quote, footings, foundations, ICF walls and waterproofing, under one accountable roof. We're members of the Simcoe County Home Builders' Association, backed by a deep local partner network — and we're the crew other builders call when the site gets hard.
Yes. The connection details are engineered case-by-case, and it's one of the most common ways owners get their first taste of ICF performance.
Usually not. Most of the structural work happens outside the existing exterior wall, and we sequence the breakthrough for late in the schedule.
Yes — any structural addition needs proper footings and foundation. That's our core trade, including on difficult ground and exposed rock.
Exterior finishes go over ICF the same way they go over framing — siding, stone, brick or stucco — so the addition can match or deliberately contrast, your call.
