01Additions
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.

What’s included
What’s included
in an addition.
Rear and second-storey additions, and everything that joins the new rooms to the old ones: structure, roof, services and the outside.
Rear additions
New footings carry the addition out into the yard. Setbacks and the lot’s remaining coverage set its size.
Second-storey additions
Another floor goes on top of the house when the structure below, foundation and framing, is shown to carry it.
Tied into the existing structure, roofline and systems
The roof sheds water because the new work’s framing, roof and services join the old. Ducts, pipes and wiring then run on as one house.
Exterior matched to the house
Windows, siding, trim and roof are chosen to match the house. The new rooms then do not look tacked on afterward.
How it runs
The whole frame,
stage by stage.
Rooms and whole houses share five stages in an identical order, and one builder answers for each.
- 01
Permits
Every addition needs a building permit, some a zoning clearance, and a regulated lot Conservation Halton.
- 02
Structure
Work that goes out gets footings. Framing then joins the house and roofline.
- 03
Trades
One schedule coordinates the electrical, plumbing and HVAC run into the new rooms.
- 04
Finishes
The inside is finished, and the exterior picks up the house’s siding, trim and windows.
- 05
Handover
Once every stage and the final are inspected, you take over the new rooms.
Why Hanna Homes
Why one builder
for all of it.
Four matters get settled at the join, by the builder, before the framing goes in.
Before any new room is drawn, it is settled whether the old foundation and framing can bear the added load.
Where the new and old roofs meet, the inspector sees the framing before it is covered. The new roof runs over that seam to the old.
Trades, coordinated by the builder around the inspections, carry pipes, ducts and wiring on across to the addition from the old rooms.
Trim, siding, roof and windows follow what the house already has. The new rooms look like part of it, not something added later.

Client reviews
Their house,
their words.
Whole homes and single rooms, in the words of the people who live in them.
02Whole home
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.
03Kitchens
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.
04Custom homes
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.
05Basement apartments
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.
06Bathrooms
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.
07Knockdown & rebuild
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.
08Basements
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.
09Whole home
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.
10Kitchens
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.

Projects
Selected work,
inside and out.
A new house, a bungalow, a bath, a basement and a kitchen are all finished: three rooms and two whole homes.
01Whole-Home Renovations
A bungalow, renewed in limewash.
Brick is limewashed, windows go floor to ceiling, cedar is under the eaves and an oak door faces a limestone forecourt.

Common questions
Common questions
in Mississauga.
What Mississauga homeowners ask about home additions: what it costs, how long it takes and what the city asks for.
The size and the way the new rooms join the house set the price, and in Mississauga the lot adds to it. Drawings must be approved before any excavation or framing, a tree of 15 cm or more across needs a permit to remove, and an arborist report goes into the application when trees are affected. No figure is quoted before drawings exist.
Design and permit review come first. Mississauga lists an addition as permit work, so the drawings are approved before excavation or framing starts, and any tree or conservation step is cleared inside that stage. After approval the build runs foundation or structure, then roof, trades and finishes, and ends at the final inspection.
A building permit, because Mississauga names an addition to an existing building as work that needs one. Depending on the lot you may also need a tree permit, Credit Valley Conservation's permit near a creek, valley or the lakeshore, and heritage approval inside a heritage conservation district.
It can. Credit Valley Conservation may require its own permit to enlarge a building within its regulated area, which covers ground beside a watercourse, a floodplain, a valley slope, a wetland or the lakeshore. Its mapping is read before the drawings are finalised, and that review can come ahead of the city permit. A rear addition puts new ground into the check, while a second storey stays on the house's footprint.
Read the Heritage District Plan before anything is drawn. Those three villages are Mississauga's heritage conservation districts, and the plan tells an owner which alterations need heritage approval, which can be required before the building permit. An addition changes the outside of the house, so it is checked against the plan first. Outside the three districts that step does not apply, and the addition goes to drawings, the building permit and any tree or conservation permit.

Before you build,
people in Mississauga ask.
What people in Mississauga search before home additions, answered for the town.
Trees of 15 cm or more across, Credit Valley Conservation's mapping and any heritage district plan. Each can put a permit or a report in front of the building permit, and a quote that skips them will change once they are read.
The city requires arborist reports on all development and construction projects except for dead trees. For an addition that touches trees it is a consultant step that goes into the application package and adds lead time before permits.
No. Mississauga lists an addition to an existing building as permit work, so excavation and framing wait until the drawings are approved. Any tree, conservation or heritage step that applies is cleared in the same stretch.

about home additions in Mississauga.
What changes the work in Mississauga: the rules, the houses and the ground.
Home addition permits in Mississauga
Mississauga lists an addition to an existing building as work that needs a building permit, so an addition cannot start until the permit drawings are approved. Design and permit review come before any excavation or framing, so a Mississauga addition starts with drawings, not excavation.
On a lot near a creek, valley slope, floodplain, wetland or the lakeshore, Credit Valley Conservation may ask for a permit of its own when a building is enlarged. The property is read against CVC mapping before drawings are finalised, since conservation review can come before the municipal permit.

House additions in Mississauga, and what joins to what
A rear addition builds out and a second-storey addition goes up. Either one is joined to the structure, roof and services the house already has, and the new rooms get the electrical, plumbing and HVAC they need, connected by the builder to what is there. The exterior is matched to the house.
In a heritage conservation district (Meadowvale Village, Old Port Credit Village or Streetsville), the Heritage District Plan says which alterations need heritage approval. Exterior changes and additions are then designed to that plan from the start.
Source: City of Mississauga: when heritage approval is required
Home addition cost and timing in Mississauga
Going out or going up, the condition of the walls and roof where the new rooms join the house, the services that have to reach them and the approvals all move the cost. Trees are an approval line of their own here, since the city asks for an arborist report on construction projects other than dead trees, and a lot with trees carries a consultant step.
The build cannot start until permit drawings are approved, and a tree, conservation or heritage step cleared along the way may push that approval back. Which of those approvals apply to your lot is what the schedule depends on.

Drawing a Mississauga addition around its trees
The plans start with the lot. If the footprint of an addition would reach a mature tree, the tree permit is sorted before site work, because a tree 15 cm (6 inches) or more across cannot be injured or removed in Mississauga without one. Tree positions are therefore marked at the design stage, and a rear addition is drawn around them where it can be.
Then comes the choice between out and up, made against the lot and the house together. The builder works from those drawings once the city approves them.
