We needed more room but didn’t want to leave the street. The second storey went on over the summer, and from the sidewalk you’d think the house was always built that way.

Home Additions in Milton
In Milton, home additions built out sit on new footings, and the framing is tied into the house and its roofline. One built up waits until the foundation and framing underneath are shown to carry another floor.

What’s included
What’s included
in an addition.
Rear or second-storey additions are covered, with all that ties new rooms into the existing house: the outside, services, roof and structure.

Rear additions
A rear addition takes new footings in the yard. Setbacks and unused lot coverage limit its size.

Second-storey additions
Building up over the house waits until the framing and foundation beneath are shown able to hold another floor.

Tied into the existing structure, roofline and systems
New roof, framing and services connect with the old. Wiring, ducts and pipes carry through as one house, and the roof sheds water.

Exterior matched to the house
Roof, windows, trim and siding match the house. That way the new rooms look like part of it, not an add-on.
How it runs
The whole frame,
stage by stage.
Whole houses and rooms alike follow the same order: five stages, each answered for by one builder.
- 01
Permits
A building permit always, a zoning clearance where needed, and Conservation Halton on a regulated lot.
- 02
Structure
Any extension gets footings first; framing connects with the house and roofline.
- 03
Trades
The new rooms get electrical, plumbing and HVAC carried into them, on one coordinated schedule.
- 04
Finishes
The inside is finished, and the exterior picks up the house’s siding, trim and windows.

Once every stage and the final are inspected, you take over the new rooms.
Why Hanna Homes
Why one builder
for all of it.
The builder has four items to settle at the join, ahead of framing the addition.
The existing foundation and framing are checked first, to see if they can take the added load. The drawings come after.
Across the seam, the new roof meets the old one. The join’s framing is left open for the inspector, and covered only after that.
From the existing rooms to the added ones, wiring, pipes and ducts keep running, and the builder coordinates each trade around inspections.
Roof, windows, trim and siding are matched to the house as it stands, which stops the new rooms reading as an add-on.

Client reviews
Their house,
their words.
Whole homes and single rooms, in the words of the people who live in them.
We put off the whole house for years because we couldn’t picture living through it. Akram walked us through every stage before it started, and each week went the way he said it would.
The crew covered the floors and cleaned up at the end of every day, which mattered with two kids at home. The new kitchen is the room everyone ends up in now. Worth every week of takeout.
Building a new house was the biggest decision we’ve ever made, and it never felt rushed. We walked the site most Saturdays and always knew exactly where things stood.
We turned the basement into a unit for my mother-in-law. She has her own entrance and her own kitchen, and we still get Sunday dinners. The paperwork I was dreading turned out to be the part I thought about least.
One bathroom is a small job for a builder, but they treated it like the whole house. The tile lines up, the door finally closes properly, and they finished the week they said they would.
Our old bungalow wasn’t worth saving, so we took it down and built new on the same lot. They kept the neighbours in the loop from demolition to the final walk-through. We love coming home to it.
The basement used to be storage and a furnace. Now it’s a family room the kids actually want to be in. A clear quote, no surprises, and the site was swept every night.
We bought an older house knowing it needed everything. Akram was straight with us from the first visit about what was worth keeping. Every room is new to us now, and it still feels like the house we fell for.
Third builder we spoke to, and the only one who returned every call. When we changed our minds about the island halfway through, they made it work without any drama.

Common questions
Common questions
in Milton.
What Milton homeowners ask about home additions: what it costs, how long it takes and what the city asks for.
Size comes first, then what the lot allows. Out or up, how the new rooms tie into the structure and systems already there, and the approvals all move the price. In Milton the approvals can include Conservation Halton, whose definition of development covers making a building bigger, and the Niagara Escarpment Commission. No figure is quoted before the drawings exist.
Drawings and approvals come first, and they are where a Milton addition stretches. A designated heritage house waits on its heritage permit, and a lot touching a Conservation Halton regulated area waits on that permit, which the authority has up to 90 days to issue. After the permits, the build runs from foundation to final inspection.
Yes, a building permit, and no addition starts without one. Depending on the lot, a Conservation Halton permit, a Niagara Escarpment Commission permit or a heritage permit may be needed too, and each is checked before the drawings are finalised. Hanna Homes runs them alongside the building permit.
Often, yes. Where the new rooms open into the house, a load-bearing wall can come out and a beam sized for what it carried goes in, under the building permit. First comes the question of which walls carry load and how the new roof meets the old one. On a designated heritage house, the heritage permit for the addition comes before this work.
Matching the exterior is part of the job, so the new rooms read as part of the house rather than as an add-on. On a designated heritage property in Milton, adding to the building needs a heritage permit, which means the look of the outside is settled before building permit work begins.

Before you build,
people in Milton ask.
What people in Milton search before home additions, answered for the town.
Yes. A designated heritage property needs a heritage permit under the Ontario Heritage Act before an addition, and that review comes ahead of the building permit work. The same lot check covers Conservation Halton and the Escarpment.
A per-square-foot rate hides what drives an addition. Whether it goes out or up, how it joins the structure and systems already there, and which approvals the lot needs all matter more. Prices come from drawings, not from a rate.
The exemption holds only if all additions to the original dwelling, the new one included, total 93 square metres or less, with further conditions on height and setbacks. Past that, a Niagara Escarpment Commission permit is needed.

What changes the work in Milton: the rules, the houses and the ground.
Home addition permits in Milton
Increasing the size of a building is one of the things Conservation Halton counts as development, along with grading the site. On a lot touching a flood plain, valley land, wetland, watercourse or steep slope, an addition needs its permit as well as the building permit, so the site check and the drawings start earlier.
On Niagara Escarpment Plan lands, an addition to a single dwelling is exempt from an NEC permit only if the total of all additions is 93 square metres or less, with further conditions on height and setbacks. Those are measured against the design before it is fixed.

House additions in Milton and what they take in
A rear addition builds out at the back and a second-storey addition goes up. Both are joined to the structure, roof and services the house already has, and the outside is matched to the house. The builder connects electrical, plumbing and HVAC for the new rooms to what is there.
Milton requires a heritage permit to alter a designated heritage property, and adding to a building is one of the alterations it names, along with replacing windows or doors. On such a house the heritage review waits ahead of the building permit work.
Home addition cost and timing in Milton
Whether the addition goes out or up, what shape the structure is in where the new rooms join it, which services have to extend and which approvals the lot needs are what move the cost. Prices come from drawings, which is why the lot checks come first.
Conservation Halton's legislated timeframe to issue a permit is 90 days, and on a regulated lot that review can run alongside the building permit review or beyond it. The practical result is that a start date is set after the permits are in hand.

Out or up on a Milton lot: setbacks and the house below
A rear addition needs room behind the house inside the setbacks. A second storey adds rooms without taking more of the yard, but the house below has to carry it, so its structure is checked first. Which one suits depends on the lot and on what the existing walls and foundation can bear.
