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.
Both rear and second-storey work is included, and so is everything that connects old and new: roof, structure, 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
Before anything goes up over your house, the framing and foundation below must be shown to take 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
The new rooms take their trim, siding, roof and windows from the house, so they do not look attached 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
Zoning clearance where one applies, Conservation Halton for a regulated lot, a building permit in every case.
- 02
Structure
Going out means footings first, and framing then ties to the house and roofline.
- 03
Trades
Electrical, plumbing and HVAC extended into the new rooms, coordinated on one schedule.
- 04
Finishes
Inside gets finished. Outside, siding, trim and windows are made to match the house.

Each stage is inspected, the final one last, and then the rooms are yours.
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.
The builder sequences the trades around the inspections, and ducts, wiring and pipes carry on from old rooms to new.
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.

Common questions
Common questions
in Oakville.
What Oakville homeowners ask about home additions: what it costs, how long it takes and what the city asks for.
The lot adds cost before the footprint does. Oakville requires regrading to leave the land able to drain and to meet existing grades along a shared lot line, which can mean swales or retaining walls, and trees above the by-law's size threshold need a removal permit. After that come the footprint or storey, the existing structure and the systems.
Lead time comes from the lot. A tree in the path of the addition needs a removal permit first, and a lot in an area regulated by Conservation Halton needs its permission before excavation. The drawings, the permit review and the inspections then set the pace, from the footings to the final. No duration is quoted before the lot is known.
Yes, an addition always needs one. Oakville adds a heritage permit when the property is designated under the Ontario Heritage Act, while a house merely listed on the Heritage Register is exempt. Where the lot touches a regulated feature, Conservation Halton's permission is needed as well, and Hanna Homes coordinates the applications.
It can. A tree 15 centimetres or more across at chest height needs a removal permit, so a tree in the footprint is settled before footings are booked, or the footprint moves around it. On a lot beside a creek valley, a slope or the lakeshore, Conservation Halton's permission is needed for most works next to those features, and its review may limit the footprint or the excavation. The addition is drawn to what the lot allows.
Yes. A load-bearing wall comes out when a beam sized to carry what it held goes in, under a building permit and inspection. Where the wall is also an exterior wall, the heritage and grading rules above still apply.

Before you build,
people in Oakville ask.
What people in Oakville search before home additions, answered for the town.
They start with the lot and the structure: setbacks and coverage for a rear addition, what the foundation and framing can carry for a second storey. In Oakville the grading, trees and conservation status are read at the same time.
A rear addition extends the house into the lot behind it. It suits a house with yard to spare inside the setbacks, and a back lot where grading and trees are not in the way.
Footprint or storey, structure, and how the new rooms connect to the old. Before the permit comes the lot check: trees, grading, conservation and heritage status.
Good to know

about home additions in Oakville.
What changes the work in Oakville: the rules, the houses and the ground.
Home addition permits in Oakville
A heritage permit is the first add-on to the building permit. Changes to a property designated under the Ontario Heritage Act need one, and properties listed in the Heritage Register without designation do not. Conservation Halton is the other approval. A lot at a ravine edge or near the lakeshore may fall under its regulation, which requires permission for most works in and beside regulated land, and that review may limit the footprint or the excavation.
House additions in Oakville: what the job covers
A rear addition digs. Its footings, window wells and entrance stairs change the grade, and Oakville requires that change to leave the land able to drain and to meet existing grades along a shared lot line, so a tight lot may need swales or retaining walls. A tree in the dig of 15 centimetres or more at chest height needs its own removal permit first. Beside a creek valley, Conservation Halton's permission covers the excavation, and it may limit how far the addition reaches. A second storey adds no footprint, so what it leans on is the foundation and framing below. Either kind is finished to match the house outside. Hanna Homes works from Burlington, about 20 minutes away.
Home addition cost and timing in Oakville
Oakville's Private Tree Protection By-law requires a permit to remove a tree 15 centimetres or more in diameter at chest height. A tree in the path of a rear addition or a side-yard excavation is therefore a lead-time item, counted in the schedule before footings are booked. The rest of the cost follows the footprint or storey, how much of the existing structure has to change to carry the new part, and how far the systems extend. The permit review and the inspections, from footings to final, set the pace once approvals are in.
Home addition plans in Oakville: before the permit
Plans for an addition settle three things: out or up, how the structure carries the new part, and how the new rooms connect to the old. Before they are final, the lot is checked for trees, grading, Conservation Halton and heritage status, since each can change the footprint. That check is also what lets the drawings go to the Town complete. An addition drawn first and checked afterwards risks a redesign once a tree permit, a grading requirement or a regulated edge turns up.
