New Custom Homes
Architectural, structural and mechanical design, the permit and the build, coordinated by one office. The Haldimand County house on our project list was taken from the client’s own plan to occupancy that way.

What’s included
A new house is the one project where every discipline is ours from the start. The structural sheet never fights the mechanical one, and the office that drew both coordinates the build.

items in your package, all from one P.Eng and BCIN team.

How it runs
Four steps from the lot to the occupancy permit, with one office answering for every drawing.
We walk the lot, check the zoning and any conservation or servicing constraints, and turn your brief or sketch into a first layout.
Architectural, structural and mechanical drawings developed together in one office, then filed for permit and followed through the city’s comments.
Excavation, foundation, framing, envelope, rough-ins and finishes by the builder we coordinate, with the engineer on site at each structural stage.
Final inspections, the occupancy permit, and a house built to the drawings you approved.

(416) 990-9179Not for a house of the size most people build. Ontario allows a BCIN-qualified designer to prepare the drawings for a house and a P.Eng to design the structure, and we hold both. Larger or unusual buildings may need an architect, and we say so at the start.
Yes. We add the structural, HVAC and electrical design the permit needs, check the plans against the zoning and the code, and coordinate the build from them. If the plans need changes to work on your lot, we make them with you.
Yes. On a serviced urban lot, Ontario’s Planning Act stops zoning from prohibiting up to three units, so a basement suite can go into the first plan instead of being converted later. We draw its entrance, its ceiling height (at least 1.95 m under the Building Code) and the separation between the units into the permit set. For a new house, the Code accepts 15.9 mm Type X gypsum board on both sides of the walls that divide the units and on the underside of the floor framing between them.
We coordinate them, after checking that the zoning allows a house and how the lot gets water, sewage and road access. Septic, well and conservation approvals each have their own process, and the permit waits on them.
Changes are priced and drawn before they are built, and structural ones are checked by the engineer on the job. Because the office that drew the house also coordinates the build, a change does not wait on an outside designer.
Only if our P.Eng confirms that the existing footings and foundation walls can carry the new house. The check covers the condition of the concrete and whether the new walls and loads line up with what is there. If they cannot, we design a new foundation with the house.
Yes. We prepare the drawings, the engineering and the permit, and you or your own contractor build from the stamped set and book the inspections against it. Who builds matters beyond the schedule, because Ontario’s builder licensing and new home warranty rules both turn on it. We go through how they apply to your arrangement before anything is signed.
Yes, with the HVAC design and from the same drawings. Ontario’s 2024 Building Code requires a new house lived in through the winter to either beat the 2012 Code’s energy efficiency levels by at least 15 per cent or conform to Chapters 1 and 3 of Supplementary Standard SB-12, Energy Efficiency for Housing. The municipality checks it at the permit stage, so it goes in with the rest of the permit set.
Our P.Eng tells you when we walk the lot. The Building Code ties minimum footing depth to the type of soil, so the footing design cannot be final until the soil is known. Where it is clay or not clearly identified, a soil report settles it.
Searched & answered
Short answers to the new custom homes questions people search most, and the broader topics they lead to.
Not covered here? Book a free consultationThe house sets it: its size, the finishes, the systems chosen and the site work the lot needs. Design and engineering are priced as separate lines from construction. Fine Engineering prices from drawings, so the quote comes after the free consultation, once there is a design to measure.
They can be. A builder repeating one plan across a subdivision can spread the design, engineering and approvals over many lots. A custom home carries those costs alone, and the owner’s choices of layout and structure add to them. Fine Engineering points out which design choices add cost as the first layout is drawn.
It depends on the lot and the house. Design and the permit come before construction, and once a complete application meets the Building Code’s criteria, the Code sets a statutory review period for a house permit. Fine Engineering gives a schedule with the quote and updates it as the municipality responds.
A heat- or energy-recovery ventilator swaps stale indoor air for fresh outdoor air and passes heat between the two airstreams on the way. A new house, or a permit with HVAC work, usually needs a mechanical ventilation design, and Toronto Building asks for one with every HVAC permit application. An HRV or ERV is the usual way to meet it. Fine Engineering sizes them in its HVAC designs.
Usually because the heat reaching the room does not match the heat it loses. A room over a garage, or one with more glass and outside wall, loses heat faster, and a long or undersized duct delivers less air than the room needs. A room-by-room heat-loss calculation and a duct design show where the gap is. Fine Engineering does both for existing houses as well as new ones.
Yes. A new bathroom means new drains, vents and water supply, and installing or changing plumbing is building permit work with its own inspections. Replacing a fixture in the same spot usually is not. The drawing shows the drain, waste and vent layout the inspector will check. Plumbing drawings for bathrooms, kitchens and second units are part of Fine Engineering’s mechanical work.
Good to know
Before you sign a construction contract, check that whoever will build the house holds a licence. In Ontario, every new home builder must be licensed by the Home Construction Regulatory Authority (HCRA). After licensing, the builder must enroll the home with Tarion before construction begins. The Building Code Act also lists an unlicensed builder or vendor among its exceptions to the duty to issue a permit.
Neither the HCRA nor Tarion enforces the Building Code. The municipality does that, through the permit and its inspections. An owner building a house for their own use is not a builder under the licensing Act, so the licence rule applies to whoever you hire to build it.
Ontario’s new home warranty law reaches a house built under contract on land the owner already holds, where one builder undertakes all the work and supplies all the materials to complete it. That builder may not sign the construction contract until it is licensed and the home is enrolled in the warranty plan. An owner who splits the work among trades, or builds as an owner-builder, may fall outside it.
New homes in Ontario carry 1-year, 2-year and 7-year warranties, administered by Tarion, that cover issues such as bad workmanship, water penetration and major structural defects. Ontario notes that homes built on existing footings or foundations may not be covered. On a teardown lot, that is a reason to settle whether the old foundation stays before the design depends on it.
A new house’s grading follows its footprint. On an open rural lot that mostly means where the house sits, while an infill lot also has to meet the neighbours’ grades at the lot lines, which can fix the foundation height before the elevations are drawn.
Our P.Eng sets the grades together with the foundation design, so the top of the foundation, the window wells and the swales are drawn as one. The grading and servicing drawings then go to the municipality with the rest of the permit set.
