Home Additions in Hamilton, Ontario
Additions Managed as Structural and Planning Projects First
Adding square footage to an existing house is harder than building new. The old structure has settled, the systems are already loaded, and every new beam has to marry into framing somebody cut decades ago. Integrated Contracting plans home additions around that reality, managing design coordination, permits, structure, and every trade on site so the new space feels original rather than bolted on. One team carries the project through occupancy.
Narrow lots in the lower city, setbacks that shift block to block, escarpment grades, and mature trees with protected root zones all decide what is buildable before design starts. We serve Hamilton, Ontario, so we read those conditions early, confirm what your property allows, and steer the design toward something the city will approve without months of revisions. Approval quirks differ from Westdale to Stoney Creek.
Managing additions on occupied homes for 18+ years has taught us that families care about two things above all: knowing when the noise ends and trusting that the numbers hold. We build detailed phasing plans, protect the occupied portion of the house, and keep one supervisor answerable for the entire scope rather than scattering responsibility across separate contractors. Drawings, approvals, and inspections stay with our office from start to finish.
Our Home Additions Services
Second Storey Additions
Lifting a roof means first proving the existing foundation and walls can carry the new load. We coordinate the engineering, the temporary weather protection, and the framing sequence so your house stays dry and structurally sound throughout the entire build.
Rear and Side Extensions
Extending into the yard opens questions about setbacks, drainage, and how the new roofline meets the old one. We resolve those details on paper first, then build a junction that will still be entirely watertight several decades later.
Garage Conversions and Additions
Turning an unheated slab into proper living space requires insulation, moisture control, and often a new floor assembly. We rebuild the envelope properly so the finished room feels like part of the house rather than an obvious afterthought.
Secondary Suite Additions
Legal suites demand separate egress, fire separation, ceiling heights, and ventilation that meet code requirements exactly. Our team manages the drawings, the approvals, and the build itself, so your rental income starts from a fully compliant and inspected unit.
Four Season Room Additions
Glass heavy spaces fail badly when the heating, insulation, and foundation get treated as afterthoughts. We build these rooms to full year round standards, so the space stays genuinely usable in February rather than becoming seasonal winter storage.
Foundation and Structural Tie Ins
New footings must match the movement of an old foundation or cracks appear exactly where the two meet. We excavate carefully, underpin wherever required, and detail the connection so the addition and the original house move together over time.
Why Owners Hand Us the Whole Scope
Space Without Moving
Land transfer tax, agent fees, and leaving a neighbourhood all add up quickly. We expand what you already own, which gives your family the room it needs while keeping the school, the street, and the neighbours.
Engineering Handled End to End
An addition is a structural problem before it is a design problem. We engage the engineer, coordinate the drawings with the architect, and build to the stamped design, so nobody hands you a set of contradictions to resolve.
Documented, Permitted Square Footage
Buyers and appraisers pay for finished, permitted area rather than potential. Because our work is inspected and recorded at every stage, the value you add shows up cleanly in a valuation instead of raising awkward questions.
Design That Matches the Original House
Nothing devalues a house faster than an addition that announces itself from the curb. We match rooflines, window proportions, and exterior materials carefully, so the finished result reads as one house rather than two stitched together.
A Single Point of Coordination
Juggling an architect, an engineer, and six trades is a job nobody wants after work. We hold every one of those relationships, so your evenings involve decisions about finishes instead of chasing a missed delivery.
Phasing That Protects Daily Life
Living through construction is manageable when somebody has planned for it. Our phasing keeps kitchens, bathrooms, and bedrooms working as long as possible, and we seal the work zone so dust stays where it belongs.
Adding Space That Belongs to Your House
Square footage is only worth what it does for the way your family actually lives. Integrated Contracting approaches every addition in Hamilton, Ontario as a structural and planning problem first, which is why the finished space feels like it belonged to the house all along instead of sitting awkwardly off the back. Whether you are adding a floor, extending a kitchen, or creating a suite for a parent, the process stays organized and the decisions stay yours. When you are ready to explore what your property will allow, send your ideas through our contact page and we will start with a realistic assessment.
frequently asked questions
How long does a second storey addition take from permit to move in?
Typical builds run six to nine months from approved permit through to occupancy, with design and approvals adding several months ahead of that. Weather, engineering revisions, and supplier lead times are the factors that shift schedules most.
Can we stay in the house during a second storey build?
Many families do stay, though the weeks when the roof is open are genuinely loud. Integrated Contracting phases work across Hamilton, Ontario homes so bedrooms and bathrooms remain usable, and we discuss temporary relocation honestly upfront.
Does our foundation need underpinning before we add a floor?
Sometimes, and it depends entirely on the existing footing size, the soil conditions, and the load you are adding. An engineer reviews the foundation before design proceeds, so nobody discovers that problem after framing is ordered.
How do you keep the house dry when the roof comes off?
Temporary roofs, tarping systems, and tightly planned demolition windows do most of the real work. We watch the forecasts closely and will delay opening the structure rather than gamble your ceilings on an overly optimistic report.
Will an addition trigger a full electrical or HVAC upgrade?
Often yes, because an older panel or a furnace sized for the original footprint simply cannot carry new rooms. We assess capacity during design and price any upgrade openly rather than raising it once the walls are closed.
What zoning limits affect how far back we can extend?
Rear yard setbacks, lot coverage limits, and height restrictions all apply, and they vary by zoning district. We check your property against the current bylaws before drawings begin, which avoids designing something that will never be approved.
How do you match brick and siding on an older home?
Exact matches on aged brick are rarely possible, so we source the closest available product and then use design breaks, banding, or a deliberate material change to make the transition look entirely intentional instead of accidental.
Who coordinates the architect and engineer on an addition?
Our team does, from start to finish. With 18+ years managing additions throughout Hamilton, Ontario, Integrated Contracting sits between the design team, the engineer, and every trade, so drawings, approvals, and site decisions move through one office.
